The Arian Heresy and Nicene Orthodoxy
“Arianism–Arianism was a 4th-century Christian heresy named for Arius (c. 250-c. 336), a priest in Alexandria [Egypt]. Arius denied the full deity of the preexistent Son of God who became incarnate in Jesus Christ. He held that the Son, while divine and like God (“of like substance”), was created by God as the agent through whom he created the universe. Arius said of the Son, “there was a time when he was not.” Arianism became so widespread in the Christian church and resulted in such disunity that the emperor Constantine convoked a church council at Nicaea in [A.D.] 325.” (from Class Handout)
