When Jesus Became God: The Struggle to Define Christianity During the Last Days of Rome Book

The Gospel narratives may suggest that Jesus was divine, but they do not insist upon it. Hundreds of years after Jesus' death, the Church councils made Jesus' divinity a central tenet of belief among many of his followers. When Jesus Became God: The Epic Fight over Christ's Divinity in the Last Days of Rome by Richard Rubenstein is a narrative history of Christians' early efforts to define Christianity by convening councils and writing creeds. Rubenstein is most interested in the battle between Arius, Presbyter of Alexandria, and Athanasius, Bishop of Alexandria. Arius said that Christ did not share God's nature but was the first creature God created. Athanasius said that Christ was fully God. At the Council of Nicea in 325, the Church Fathers came down on Athanasius's side and made Arius's belief a heresy.

Rubenstein's brisk, incisive prose brings the councils' 4th-century Roman setting fully alive, with riots, civil strife, and spectacular public debates. Rubenstein is also personally invested in the meaning of these councils for religious life today: he wrote this book, in part, because he grew up in a mixed Jewish Catholic neighborhood and was bewildered by animosity between the religious groups on his block. Digging back in history, Rubenstein learns that before the Arian controversy, "Jews and Christians could talk to each other and argue among themselves about crucial issues like the divinity of Jesus.... They disagreed strongly about many things, but there was still a closeness between them." But when the controversy was settled, Rubenstein notes, "that closeness faded. To Christians, God became a Trinity and heresy became a crime. Judaism became a form of infidelity. And Jews living in Christian countries learned not to think very much about Jesus and his message." --Michael Joseph Gross
