On Christianity's highest holy day, three new books about different aspects of the religion.
Font of Life: Ambrose, Augustine and the Mystery of Baptism (Oxford) by Garry Wills, focuses on a key moment in early Christianity, the baptism of St. Augustine by St. Ambrose in Milan on Easter of 387, which linked the two most powerful men in the nascent church.
The Sign: The Shroud of Turin and the Secret of the Resurrection (Dutton) by Thomas de Wesselow is an art historian's new interpretation of the relic once revered by Christians but long held to be a fake, analyzing its science and the cultural and historical clues to its meaning.
When God Talks Back: Understanding the American Evangelical Relationship With God (Knopf) by T.M. Luhrmann is a psychological anthropologist's look at the history of the evangelical movement and the mental and emotional effects of prayer.
