AbstractWhy should Christians from churches of the Reformation be marking the 1700th anniversary of Nicaea? Some Christians from such churches regard Nicaea as emblematic of Christianity's “fall” from the radical and subversive faith of Jesus’ teaching, miracles, and welcome to become an abstract and theological discourse dependent not on the Bible but on Greek philosophy. Some ask why they should pay any attention to a long ago gathering of male bishops or let that gathering, rather than simply the Bible and their own personal faith experience, shape their understanding of Christianity. In this paper, the author, herself from a church often inclined to such Protestant critiques of Nicaea, suggests a more open approach and a positive understanding of Nicaea for today's church.
