"Who do you say that I am?" This question that Jesus asked of his disciples, so central to his mission, became equally central to the fledgling church. How would it respond to the Gnostics who answered by saying Jesus was less than fully human? How would it respond to the Arians who contended he was less than fully God? It was these challenges that ultimately provoked the Council of Nicaea in A.D. 325. In this volume covering the first half of the article in the Nicene Creed on God the Son, John Anthony McGuckin shows how it countered these two errant poles by equally stressing Jesus' authentic humanity (that is, his fleshliness and real embodiment in space and time) and his spiritual glory or full divinity. One cottage industry among some historical theologians, he notes, has been to live in a fever of conspiracy theory where orthodox oppressors dealt heavy-handedly with poor heretics. Or the picture is painted of ancient grassroots inclusivists being suppressed by establishment elites. The reality was far from such romantic notions. It was in fact the reverse. The church who denounced these errors did so in the name of a greater inclusivity based on common sense and common education. The debate was conducted generations before Christian bishops could ever call on the assistance of secular power to enforce their views. Establishing the creeds was not a reactionary movement of censorship but rather one concerned with the deepest aspects of quality control. Ultimately, what was and is at stake is not fussy dogmatism but the central gospel message of God's stooping "down in mercy to enter the life of his creatures and share their sorrows with them. He has lifted up the weak and the broken to himself, and he healed their pain by abolishing their alienation."

Constantine and the Council of Nicaea plunges students into the theological debates confronting early Christian church leaders. Emperor Constantine has sanctioned Christianity as a legitimate religion within the Roman Empire but discovers that Christians do not agree on fundamental aspects of their beliefs. Some have resorted to violence, battling over which group has the correct theology. Constantine has invited all of the bishops of the church to attend a great church council to be held in Nicaea, hoping to settle these problems and others. The first order of business is to agree on a core theology of the church to which Christians must subscribe if they are to hold to the "true faith." Some will attempt to use the creed to exclude their enemies from the church. If they succeed, Constantine may fail to achieve his goal of unity in both empire and church. The outcome of this conference will shape the future of Christianity for millennia. Free supplementary materials for this textbook are available at the Reacting to the Past website.
