A Christian ( pronunciation ) is a person who adheres to Christianity, an Abrahamic, monotheistic religion based on the life and teachings of Jesus Christ. "Christian" derives from the Koine Greek word Christós (Χριστός), a translation of the Biblical Hebrew term mashiach.

There are diverse interpretations of Christianity which sometimes conflict. However, "Whatever else they might disagree about, Christians are at least united in believing that Jesus has a unique significance." The term "Christian" is also used adjectivally to describe anything associated with Christianity, or in a proverbial sense "all that is noble, and good, and Christ-like." It is also used as a label to identify people who associate with the cultural aspects of Christianity, irrespective of personal religious beliefs or practices.

According to a 2011 Pew Research Center survey, there were 2.2 billion Christians around the world in 2010, up from about 600 million in 1910. By 2050, the Christian population is expected to exceed 3 billion. According to a 2012 Pew Research Center survey Christianity will remain the world's largest religion in 2050, if current trends continue.

The Georgian Apostolic Autocephalous Orthodox Church (Georgian: საქართველოს სამოციქულო ავტოკეფალური მართლმადიდებელი ეკლესია, sak’art’velos samots’ik’ulo avt’okep’aluri mart’lmadidebeli eklesia) is an autocephalous Eastern Orthodox Church. It is Georgia's dominant religious institution, and a majority of Georgian people affirm their membership in the Church. It asserts apostolic foundation, and its historical roots can be traced to the conversion of the Kingdom of Iberia to Christianity in the 4th century AD. Christianity, as embodied by the Church, was the state religion of Georgia until 1921, when a constitutional change separated church and state.

The Georgian Orthodox Church is in full communion with the other churches of Eastern Orthodoxy. Its autocephaly is recognized by other Orthodox bodies, including the Ecumenical Patriarchate of Constantinople since 1990. As in similar autocephalous Orthodox churches, the Church's highest governing body is the Holy Synod of bishops. It is headed by the Catholicos-Patriarch of All Georgia. The current Patriarch is Ilia II, who was elected in 1977.
