The '''First Ecumenical Council''' was held in Nicea in 325 A.D. 325 and set a pattern for all later [[Ecumenical Councils]]. It primarily addressed the issue of [[Arianism]] (producing the original version of the [[Nicene Creed]]) and set a universal pattern for calculating the date of [[Pascha]]—the [[Paschalion]]. It is also referred to as the '''First Council of Nicea'''.
