Cultural anthropologist, Carol Delaney, returns to Religion For Life to discuss her latest book, Columbus and the Quest for Jerusalem.  We know the children's rhyme:  "In 1492 Columbus sailed the ocean blue."  But why?  Because he wanted to find gold in order to start a crusade to conquer Jerusalem for the Christians so that Christ would return.   Professor Delaney takes us into the medieval mindset and helps us understand Columbus in his time and place.   I discussed her book in a recent sermon and you can hear her provocative thesis on Religion For Life.
