plays the photopotential (photo-induced open circuit potential) varia-
tions of the TiO2 NTA and β-Bi2O3-TiO2 NTA films in the 0.5 M Na2SO4
solution under intermittent white light illumination and open-circuit
conditions. Before the white light illumination (dark conditions), the
potentials of TiO2 NTA and β-Bi2O3-TiO2 NTA films were about
−110 mV (vs. SCE) and −200 mV (vs. SCE), respectively. When the
films were separately illuminated, their potentials shifted in the nega-
tive direction because of the generation of photoelectrons in these two
semiconductor films. For the bare TiO2 NTA film, its photopotential was
about −280 mV (vs. SCE), which was 170 mV lower than its original
open-circuit potential (namely the potential before illumination).
Especially, the photopotential of the β-Bi2O3-TiO2 NTA film reached
about −460 mV (vs. SCE), which was 260 mV lower than its original
open-circuit potential. That is to say, the photopotential of the β-Bi2O3-
TiO2 NTA film was more negative than that of the bare TiO2 NTA film
under white light illumination, which indicated that the β-Bi2O3-TiO2

present the solution resistance, charge transfer resistance and constant
phase element, respectively. The main objective of the EIS measure-
ments is to obtain the Rct value of the coupled 403SS in the corrosion
cell for the comparison between illumination and dark conditions. For
simplicity, the EIS analysis focused on the effect of the film under white
light illumination on the coupled steel. The fitting results showed that
the Rct of the uncoupled 403SS was 287.70 ± 4.32 kΩ cm2, but de-
creased sharply to 19.53 ± 0.23 kΩ cm2 and 6.24 ± 0.25 kΩ cm2
when the 403SS was coupled with the bare TiO2 and β-Bi2O3-TiO2 NTA
composite films under white light illumination, respectively. When the
403SS was coupled with the film photoanode under illumination, the
photogenerated electrons were transferred from the photoanode to the
steel to participate in the electrochemical reactions, which accelerated
the cathodic reaction at the steel/solution interface and showed a lower
Rct value. Therefore, the 403SS was polarized cathodically and its
corrosion was reduced. Furthermore, the Rct value of the 403SS coupled
with the composite film was lower than that coupled with the bare TiO2
film, suggesting that the composite film under illumination could pro-
vide more electrons due to its superior photoelectrochemical perfor-
mance, which was in agreement with the foregoing analysis results.
Thus, it is conclusive that the prepared β-Bi2O3-TiO2 NTA composite
film could provide a higher cathodic current density under white light

The American Sabbath Tract Society is the publishing agency of
the denomination. Its head-quarters are at Alfred Center, N. Y. It
publishes the Sabbath Recorder, the organ of the S. D. Baptists, and
it also publishes a series of valuable works relating to the Sabbath
and the law of God.
During the two hundred years which have elapsed since the
organization of the first Sabbatarian church in America, God has
raised up among this people men of eminent talent and moral worth.
He has also in providential ways called attention to the sacred trust
which he so long since confided to the S. D. Baptists, and which they
have been slow to realize in its immense importance.
Among those converted to the Sabbath through the agency of this
people, the name of J. W. Morton is particularly worthy of honorable
mention. He was sent in 1847 a missionary to the island of Hayti by
the Reformed Presbyterians. Here he came in contact with
Sabbatarian publications, and after a serious examination became
satisfied that the seventh day is the Sabbath of the Lord. As an
honest man, what he saw to be truth he immediately obeyed, and
returning home to be tried for his heresy, was summarily expelled
from the Reformed Presbyterian church without being suffered to
state the reasons which had governed his conduct. He has given to
the world a valuable work, entitled, “Vindication of the True Sabbath,”
in which his experience is related, and his reasons for observing the
seventh day set forth with great force and clearness.
The S. D. Baptists do not lack men of education and of talent, and
they have ample means in their possession with which to sustain the
cause of God. If in time past they have not fully realized that they
were debtors to all mankind because of the great truth which God
committed to their trust, there is reason to believe that they are now
to some extent awakening to this vast indebtedness.[1100]
There is also in the State of Pennsylvania a small body of German
S. D. Baptists found in the counties of Lancaster, York, Franklin, and
Bedford, and in the central and western parts of the State. They
originated in 1728 from the teaching of Conrad Beissel, a native of
Germany. They practice trine immersion, and the washing of feet,
and observe open communion. They encourage celibacy, but make it
obligatory upon none. Even those who have chosen this manner of
life are at liberty to marry if at any time they choose so to do. They
established and successfully maintained a Sabbath-school at
Ephrata, their head-quarters, forty years before Robert Raikes had
introduced the system of Sunday-schools. This people have suffered
much persecution because of their observance of the seventh day,
the laws of Pennsylvania being particularly oppressive toward
Sabbatarians.[1101] The German S. D. Baptists do not belong to the
S. D. Baptist General Conference.
We have already noticed the fact that Sabbath-keepers are
numerous in Russia, in Poland, and in Turkey. We find the following
statement respecting Sabbath-keepers in Hungary:—
The probability is that as the laws of the Austrian Empire bear very
heavily upon all religious bodies not belonging to some one of the
tolerated sects or orders, these “Seventh-day Christians” on “being
refused tolerance” in their own name, secured the privilege of
observing the seventh day by allowing their doctrine to be classed by
the civil authorities under the head of Judaism, and so bringing
themselves under the tolerance accorded to the “received religions.”
We do not say that this was right, even as a technicality, but it is
evidently the extent of what they did. There is no reason to believe
that they abjured Christ. We also learn that there are Sabbath-
keepers in the north of Asia:—
It was but a few months after Eld. Bates, that our esteemed and
efficient brother, Eld. James White, also embraced the Sabbath. He
had labored with much success in the great Advent movement, and
he now entered heartily into the work of Sabbath reform. Uniting with
Eld. Bates in the proclamation of the doctrine of the advent and the
Sabbath as connected together in the Sanctuary and the message of
the third angel, he has, with the blessing of God, accomplished great
results in behalf of the Sabbath.
The publishing interests of the Seventh-day Adventists originated
through his instrumentality. He began the work of publishing in 1849,
without resources, and with very few friends, but with much toil, self-
sacrifice, and anxious care; and with the blessing of God upon his
efforts, he has been the means of establishing an efficient office of
publication, and of disseminating many important works throughout
our country, and, to some extent, to other nations also. The
publication of the Advent Review and Herald of the Sabbath, the
organ of the Seventh-day Adventists, was commenced by him in
1850. For most of the years of its existence, he has served as one of
its editors; and for all its earlier years, he was both publisher and
sole editor. During this time, he has also labored with energy as a
minister of the gospel of Christ.
The wants of the cause demanding an enlargement of capital and
more extensive operations, to this end an Association was
incorporated in the city of Battle Creek, Michigan, May 3, 1861,
under the name of the Seventh-day Adventist Publishing
Association. This Association owns three commodious publishing
houses, with engine, power presses, and all the fixtures necessary
for doing an extensive business. There are about fifty persons
constantly employed in this work of publication. The Association has
a capital of about $82,000. Under God, it owes its prosperity to the
prudent management and untiring energy of Eld. James White.
The Advent Review has at the present time (Nov., 1873) a
circulation of about 5000 copies. The Youth’s Instructor, a monthly
paper designed for the children of Sabbath-keeping Adventists,
began to be issued in 1852, and has now attained a circulation of
nearly 5000 copies.
The Advent Tidende, a Danish monthly with a circulation of 800, is
published for the benefit of those who speak the Danish and
Norwegian tongues, of whom a considerable number have
embraced the Sabbath.
The S. D. Adventists have taken a strong interest in the subject of
hygiene and the laws of health, and have established a Health
Institute at Battle Creek, Mich., which publishes the Health Reformer,
a monthly journal, magazine form, having a circulation of nearly 5000
copies.
Numerous publications on Prophecy, the Signs of the Times, the
Coming of Christ, the Sabbath, the Law of God, the Sanctuary, &c.,
&c., have been issued within the past twenty years, and have had an
extensive circulation, amounting, in the aggregate, to many millions
of pages.
The ordinary financial wants of the cause are sustained by a
method of collecting means known as Systematic Benevolence. By
this system, it is designed that each friend of the cause shall pay a
certain sum weekly proportioned to the property which he
possesses. But there is no compulsion in this matter. In this manner
the burden is borne by all, so that it rests heavily upon none; and the
means needed for the work flows with a steady stream into the
treasury of the several churches, and finally into that of the State
Conferences. A settlement is instituted each year at the State
Conferences, in which the labors, receipts, and expenditures, of
each minister are carefully considered. Thus none are allowed to
waste means, and none who are recognized as called of God to the
ministry are allowed to suffer.
The churches sustain their meetings for the most part without the
aid of preaching. They raise means to sustain the servants of Christ,
but bid them mainly devote their time and strength to save those who
have not the light of these important truths shining upon their
pathway. So they go out everywhere preaching the word of God, as
his providence guides their feet. During the summer months, the
work in new fields is carried forward principally by means of large
tents, which enable the preacher to provide a suitable place of
worship, wherever he may think it desirable to labor.
The Seventh-day Adventists have thirteen State Conferences,
which assemble annually in their respective States. These bear the
names of Maine, Vermont, New England, New York and
Pennsylvania, Ohio, Michigan, Indiana, Illinois, Wisconsin,
Minnesota, Iowa, Missouri and Kansas, and California. These
Conferences are designed to meet the local wants of the cause.
There is also a General Conference, which assembles yearly,
composed of delegates from the State Conferences. This
Conference takes the general oversight of the work in all the State
Conferences, supplying the more destitute with laborers as far as
possible, and uniting the whole strength of the body for the
accomplishment of the work. It also takes the charge of missionary
labor in those States which have no organized Conferences.
There are about fifty ministers who devote their whole time to the
work of the gospel. There is also a considerable number who preach
a portion of the time and devote the remainder to secular labor.
There are about 6000 members in the several Conference
organizations. But such is the scattered condition of this people (for
they are found in all the northern States and in several of the
southern), that a very large portion have no connection with its
organization. They are to be found in single families scattered all the
way from Maine to California and Oregon. The Review and Instructor
constitute, in a great number of cases, the only preachers of their
faith.
Those subjects which more especially interest this people, are the
fulfillment of prophecy, the second personal advent of the Saviour as
an event now near at hand, immortality through Christ alone, a
change of heart through the operation of the Holy Spirit, the
observance of the Sabbath of the fourth commandment, the divinity
and mediatorial work of Christ, and the development of a holy
character by obedience to the perfect and holy law of God.[1107]
They are very strict with regard to the ordinance of baptism,
believing not only that it requires men to be buried in the watery
grave, but that even such baptism is faulty if administered to those
who are breaking one of the ten commandments. They also believe
that our Lord’s direction in John 13 should be observed in connection
with the supper.
They teach that the gifts of the Spirit set forth in 1 Cor. 12 and
Eph. 4, were designed to remain in the church till the end of time.
They believe that these were lost in consequence of the same
apostasy that changed the Sabbath. They also believe that in the
final restoration of the commandments by the work of the third angel,
the gifts of the Spirit of God are restored with them. So the remnant
of the church, or last generation of its members, is said to “keep the
commandments of God, and have the testimony of Jesus
Christ.”[1108] And the angel of God explains this by saying, “The
testimony of Jesus is the spirit of prophecy.”[1109] The spirit of
prophecy therefore has a distinct place assigned to it in the final
work of Sabbath reform. Such are their views of this portion of
Scripture; and their history from the beginning has been marked by
the influence of this sacred gift.
In the face of strong opposition, the people known as Seventh-day
Adventists have arisen to bear their testimony for the Sabbath of the
Lord. They have had perils from open foes, and from false brethren;
but they have thus far overcome the difficulties of the way, and from
each have gathered strength for the conflict before them. They have
a definite work which they hope to accomplish. It is to make ready a
people prepared for the advent of the Lord.
Honorable mention should be made of the Seventh-day Adventists
of Switzerland. They first learned these precious truths from Elder M.
B. Czechowski, who a few years since instructed them in the
commandments of God and the faith of Jesus. Since his labors with
them ceased, God has given them strength to stand with firmness for
his truth, and has added to their numbers. They have a heart to obey
the truth and to sacrifice for its advancement. They number about
sixty persons. There are a few individuals of this faith also in Italy,
Germany, and Denmark.
The observance of the Sabbath is sometimes advocated on the
ground that man needs a day of rest and will grow prematurely old if
he labor seven days in each week, which is doubtless true; and it
has also been advocated on the ground that God will bless in basket
and in store those who hallow his Sabbath, which may be true in
many cases; but the Bible does not urge motives of this kind in
respect to this sacred institution. Without doubt there are great
incidental advantages in the observance of the Sabbath. But these
are not what God sets before us as the reasons for its observance.
The true reason is infinitely higher than all considerations of this
kind, and should constrain men to obey, even were it certain that it
would cost them all that is dear in the present life.
The Sabbath has been advocated on the ground that it secures to
men a day for divine worship in which by common consent they may
appear before God. This is a very important consideration, and yet
the Bible says little concerning it. It is one of the incidental blessings
of the Sabbath, and not the chief reason for its observance. The
Sabbath was ordained to commemorate the creation of the heavens
and the earth.
The importance of the Sabbath as the memorial of creation is that
it keeps ever present the true reason why worship is due to God. For
the worship of God is based upon the fact that he is the Creator and
that all other beings were created by him. The Sabbath therefore lies
at the very foundation of divine worship, for it teaches this great truth
in the most impressive manner, and no other institution does this.
The true ground of divine worship, not of that on the seventh day
merely, but of all worship, is found in the distinction between the
Creator and his creatures. This great fact can never become
obsolete, and must never be forgotten. To keep it in man’s mind,
God gave to him the Sabbath. He received it in his innocency, and
notwithstanding the perversity of his professed people, God has
preserved this sacred institution through the entire period of man’s
fallen state.
The four and twenty elders in the very act of worshiping Him who
sits upon the throne, state the reason why worship is due to God:—
“For as the new heavens and the new earth, which I will
make shall remain before me, saith the Lord, so shall your
seed and your name remain. And it shall come to pass, that
from one new moon to another, and from one Sabbath to
another, shall all flesh come to worship before me, saith the
Lord.”[1113]
Does not Paul refer to these very facts set forth by Isaiah when he
says, “There remaineth therefore a rest [Greek, Sabbatismos,
literally “a keeping of the sabbath”] to the people of God”?[1114]
The reason for this monthly gathering to the New Jerusalem of all
the host of the redeemed from every part of the new earth may be
found in the language of the Apocalypse:—
“And he showed me a pure river of water of life, clear as
crystal, proceeding out of the throne of God and of the Lamb.
In the midst of the street of it, and on either side of the river
was there the tree of life, which bare twelve manner of fruits
and yielded her fruit every month; and the leaves of the tree
were for the healing [literally, the service][1115] of the
nations.”[1116]
The gathering of the nations that are saved to the presence of the
Creator, from the whole face of the new earth on each successive
Sabbath, attests the sacredness of the Sabbath even in that holy
state, and sets the seal of the Most High to the perpetuity of this
ancient institution.

[3] Dr. Adam Clarke, in his Commentary on Gen. 1:1, uses the
following language: “Created] Caused that to exist which
previously to this moment, had no being. The rabbins, who are
legitimate judges in a case of verbal criticism on their own
language, are unanimous in asserting that the word bara,
expresses the commencement of the existence of a thing: or its
egression from nonentity to entity.... These words should be
translated: ‘God in the beginning created the substance of the
heavens and the substance of the earth; i. e., the prima materia,
or first elements, out of which the heavens and the earth were
successively formed.’”
Purchase’s Pilgrimage, b. i. chap, ii., speaks thus of the
creation: “Nothing but nothing had the Lord Almighty, whereof,
wherewith, whereby, to build this city” [that is the world].
Dr. Gill says: “These are said to be created, that is, to be made
out of nothing; for what pre-existent matter to this chaos [of verse
2] could there be out of which they could be formed?”
“Creation must be the work of God, for none but an almighty
power could produce something out of nothing.” Commentary on
Gen. 1:1.
John Calvin, in his Commentary on this chapter, thus expounds
the creative act: “His meaning is, that the world was made out of
nothing. Hence the folly or those is refuted who imagine that
unformed matter existed from eternity.”
The work of creation is thus defined in 2 Maccabees 7:28:
“Look upon the heaven and the earth, and all that is therein, and
consider that God made them of things that were not; and so was
mankind made likewise.”
That this creative act marked the commencement of the first
day instead of preceding it by almost infinite ages is thus stated in
2 Esdras 6:38: “And I said, O Lord, thou spakest from the
beginning of the creation, even the first day, and saidst thus: Let
heaven and earth be made; and thy word was a perfect work.”
Wycliffe’s translation, the earliest of the English versions,

and earth.”

striking passage:
“The Hebrew root for seven signifies fullness, perfection, and
the Jews held many mysteries to be in the number seven: so
John in his Apocalypse useth much that number. As, seven
churches, seven stars, seven spirits, seven candlesticks, seven
angels, seven seals, seven trumpets; and we no sooner meet
with a seventh day, but it is blessed; no sooner with a seventh
man [Gen. 5:24; Jude 14], but he is translated.” Page 7.

hallow. Ed. 1859.
The revised edition of 1864 gives this definition: “To make
sacred or holy; to set apart to a holy or religious use; to
consecrate by appropriate rites; to hallow. God blessed the
seventh day, and sanctified it. Gen. 2:3. Moses ... sanctified
Aaron and his garments. Lev. 8:30.”

ends; to consecrate; to hallow. God blessed the seventh day and

[21] Dr. Lange’s Commentary speaks on this point thus, in vol. i,
p. 197: “If we had no other passage than this of Gen. 2:3, there
would be no difficulty in deducing from it a precept for the
universal observance of a Sabbath, or seventh day, to be devoted
to God, as holy time, by all of that race for whom the earth and its
nature were specially prepared. The first men must have known it.
The words, ‘He hallowed it,’ can have no meaning otherwise.
They would be a blank unless in reference to some who were
required to keep it holy.”
Dr. Nicholas Bound, in his “True Doctrine of the Sabbath,”
London, 1606, page 7, thus states the antiquity of the Sabbath
precept:
“This first commandment of the Sabbath was no more then first
given when it was pronounced from Heaven by the Lord, than any
other one of the moral precepts, nay, that it hath so much
antiquity as the seventh day hath being; for, so soon as the day
was, so soon was it sanctified, that we might know that, as it
came in with the first man, so it must not go out but with the last
man; and as it was in the beginning of the world, so it must
continue to the end of the same; and, as the first seventh day was
sanctified, so must the last be. And this is that which one saith,
that the Sabbath was commanded by God, and the seventh day
was sanctified of him even from the beginning of the world; where
(the latter words expounding the former) he showeth that, when
God did sanctify it, then also he commanded it to be kept holy;
and therefore look how ancient the sanctification of the day is, the
same antiquity also as the commandment of keeping it holy; for
they two are all one.”

[29] Dr. Twisse illustrates the absurdity of that view which
makes the first observance of the Sabbath in memory of creation
to have begun some 2500 years after that event: “We read that
when the Ilienses, inhabitants of Ilium, called anciently by the
name of Troy, sent an embassage to Tiberius, to condole the
death of his father Augustus, he, considering the
unseasonableness thereof, it being a long time after his death,
requited them accordingly, saying that he was sorry for their
heaviness also, having lost so renowned a knight as Hector was,
to wit, above a thousand years before, in the wars of Troy.”—

[64] On this verse Dr. A. Clarke thus comments:—“On the sixth
day they gathered twice as much—This they did that they might
have a provision for the Sabbath.”
[65] The Douay Bible reads: “To-morrow is the rest of the
Sabbath sanctified unto the Lord.” Dr. Clarke comments as
follows upon this text: “To-morrow is the rest of the holy Sabbath.
There is nothing either in the text or context that seems to
intimate that the Sabbath was now first given to the Israelites, as
some have supposed; on the contrary, it is here spoken of as
being perfectly well known, from its having been generally
observed. The commandment, it is true, may be considered as
being now renewed; because they might have supposed, that in
their unsettled state in the wilderness, they might have been
exempted from the observance of it. Thus we find, 1. That when
God finished his creation he instituted the Sabbath; 2. When he
brought the people out of Egypt, he insisted on the strict
observance of it; 3. When he gave the law, he made it a tenth
part of the whole: such importance has this institution in the eyes
of the Supreme Being!”
Richard Baxter, a famous divine of the seventeenth century,
and a decided advocate of the abrogation of the fourth
commandment, in his “Divine Appointment of the Lord’s Day,”
thus clearly states the origin of the Sabbath: “Why should God
begin two thousand years after [the creation of the world] to give
men a Sabbath upon the reason of his rest from the creation of it,
if he had never called man to that commemoration before? And it
is certain that the Sabbath was observed at the falling of the
manna before the giving of the law; and let any considering
Christian judge..... 1. Whether the not falling of the manna, or the
rest of God after the creation, was like to be the original reason of
the Sabbath. 2. And whether if it had been the first, it would not
have been said, Remember to keep holy the Sabbath-day; for on
six days the manna fell, and not on the seventh; rather than ‘for in
six days God created heaven and earth, &c., and rested the
seventh day.’ And it is casually added, ‘Wherefore the Lord
blessed the Sabbath-day, and hallowed it.’ Nay, consider whether
this annexed reason intimates not that the day on this ground
being hallowed before, therefore it was that God sent not down
the manna on that day, and that he prohibited the people from
seeking it.”—Practical Works, Vol. iii. p. 784. ed. 1707.
[66] The Douay Bible reads: “Because it is the Sabbath of the
Lord.”
[67] Ex. 16.
[68] It has indeed been asserted that God by a miracle
equalized the portion of every one on five days, and doubled the
portion of each on the sixth, so that no act of the people had any
bearing on the Sabbath. But the equal portion of each on the five
days was not thus understood by Paul. He says: “But by an
equality, that now at this time your abundance may be a supply
for their want, that their abundance also may be a supply for your
want; that there may be equality; as it is written, He that had
gathered much had nothing over; and he that had gathered little
had no lack.” 2 Cor. 8:14, 15. And that the double portion on the
sixth day was the act of the people, is affirmed by Moses. He says
that “on the sixth day they gathered twice as much bread.” Verse
22.
[69] Gen. 7:4, 10; 8:10, 12; 29:27, 28; 50:10; Ex. 7:25; Job
2:13.
[70] By this three-fold miracle, occurring every week for forty
years, the great Law-giver distinguished his hallowed day. The
people were therefore admirably prepared to listen to the fourth
commandment enjoining the observance of the very day on which
he had rested. Ex. 16:35; Josh. 5:12; Ex. 20:8-11.
[71] The twelfth chapter of Exodus relates the origin of the
passover. It is in striking contrast with Ex. 16, which is supposed
to give the origin of the Sabbath. If the reader will compare the
two chapters he will see the difference between the origin of an
institution as given in Ex. 12, and a familiar reference to an
existing institution as in Ex. 16. If he will also compare Gen. 2 with
Ex. 12, he will see that the one gives the origin of the Sabbath in
the same manner that the other gives the origin of the passover.
[72] This implies, first, the fall of a larger quantity on that day,
and second, its preservation for the wants of the Sabbath.
[73] This must refer to going out for manna, as the connection
implies; for religious assemblies on the Sabbath were
commanded and observed. Lev. 23:3; Mark 1:21; Luke 4:16; Acts
1:12; 15:21.
[74] John 7:22.
[75] Gen. 17:34; Ex. 4. Moses is said to have given
circumcision to the Hebrews; yet it is a singular fact that his first
mention of that ordinance is purely incidental, and plainly implies
an existing knowledge of it on their part. Thus it is written: “This is
the ordinance of the passover: There shall no stranger eat
thereof; but every man’s servant that is bought for money, when
thou hast circumcised him, then shall he eat thereof.” Ex. 12:43,
44. And in like manner when the Sabbath was given to Israel, that
people were not ignorant of the sacred institution.

[78] That the Lord was there in person with his angels, see
besides the narrative in Ex. 19; 20; 32-34, the following

[79] Ex. 24:10; Lev. 22:32, 33; Num. 15:41; Isa. 41:17.
[80] Ps. 147:19, 20; Rom. 3:1, 2; 9:4, 5. The following from the
pen of Mr. Wm. Miller presents the subject in a clear light: “I say,
and believe I am supported by the Bible, that the moral law was
never given to the Jews as a people exclusively; but they were for
a season the keepers of it in charge. And through them the law,
oracles, and testimony, have been handed down to us. See Paul’s
clear reasoning in Rom. chapters 2, 3, and 4, on that point.”—
Miller’s Life and Views, p. 161.
[81] Ex. 19; Deut. 7:6; 14:2; 2 Sam. 7:23; 1 Kings 8:53; Amos
3:1, 2.
[82] Ex. 20:1-17; 34:28, margin; Deut. 5:4-22; 10:4, margin.
[83] Deut. 5:22.
[84] He who created the world on the first day of the week, and
completed its organization in six days, rested on the seventh day,
and was refreshed. Gen. 1; 2; Ex. 31:17.
[85] To this, however, it is objected that in consequence of the
revolution of the earth on its axis, the day begins earlier in the
East than with us; and hence that there is no definite seventh day
to the world of mankind. To suit such objectors, the earth ought
not to revolve. But in that case, so far from removing the difficulty,
there would be no seventh day at all; for one side of the globe
would have perpetual day and the other side perpetual night. The
truth is, everything depends upon the revolution of the earth. God
made the Sabbath for man [Mark 2:27]; he made man to dwell on
all the face of the earth [Acts 17:26]; he caused the earth to
revolve on its axis that it might measure off the days of the week;
causing that the sun should shine on the earth, as it revolves from
west to east, thus causing the day to go round the world from east
to west. Seven of these revolutions constitute a week; the
seventh one brings the Sabbath to all the world.
[86] Luke 23:54-56; 24:1.
[87] See also Matt. 28:1; Mark 16:1, 2.
[88] Neh. 9:13, 14.
[89] This expression is strikingly illustrated in the statement of
Eze. 20:5, where God is said to have made himself known unto
Israel in Egypt. This language cannot mean that the people were
ignorant of the true God, however wicked some of them might be,
for they had been God’s peculiar people from the days of
Abraham. Ex. 2:23-25; 3:6, 7; 4:31. The language implies the
prior existence both of the Law-giver and of his Sabbath, when it
is said that they were “made known” to his people.
[90] It should never be forgotten that the term Sabbath day
signifies rest-day; that the Sabbath of the Lord is the rest-day of
the Lord; and hence that the expression, “Thy holy Sabbath,”
refers the mind to the Creator’s rest-day, and to his act of blessing
and hallowing it.
