These days a conference takes place about the Council of Nicea in Cairo, organized by Dr. Jos Strengholt. In one of the lectures, Dr. Boris Paschke (ETF Leuven) quotes the following description of Arius (whose denial of Jesus’ deity was condemned in Nicea):

Epiphanius: “He was very tall in stature, with downcast countenance—counterfeited like a guileful serpent, and well able to deceive any unsuspecting heart through its cleverly designed appearance. For he was always garbed in a short cloak and sleeveless tunic; he spoke gently, and people found him persuasive and flattering.” Rowan Williams: “A guru, we might almost say.”
