When Jesus Became God: The Epic Fight over Christ's Divinity in the Last Days of Rome, by Richard E. Rubenstein
Richard Rubenstein's concern with the question of Jesus's divinity began in his boyhood, when some Catholic boys knocked him down and called him a Jewish Christ-killer. He began to research and write about the subject in the '70s, when a French landlord provided him with an extensive library on the Arian controversy. His story of the Council of Nicaea and the squabbles that followed it is interestingly written, though the book's title is theologically sloppy. Could Jesus "become" God? And could judgments by various church councils turn a human Jesus into God?
