THE FIRST COUNCIL OF NICAEA (325 A.D.): CIRCUMSTANCES AND IMAGES

Last year, 2025, marked 1700 years since the Ecumenical Council whose proceedings took place in the city of Nicaea in the year 325 AD. It was convened by Emperor Constantine I (306–337). Twelve hundred hierarchs participated, each accompanied by a group of clergy necessary for the conduct of the proceedings. The total number was around 20,000 people—a truly impressive figure for such a synod. This gathering was necessary for the unification of the Christian Church throughout the entire Roman Empire. By that time, Christians had come to represent approximately 50–60% of the total population. Through the work of the Council, the first version of the Creed was drafted, which was later defined in 396 AD by the Ecumenical Council of Constantinople. Through the decisions of the Council of Nicaea, the emperor—who presided over the proceedings—approved all the canons that would form the foundation of the Christian Church. On this occasion, all doctrinal deviations from the Christian faith were refuted. Thus, Arius’s doctrine from Alexandria, concerning the concept of filioque, was rejected. In the end, the council succeeded, for a short time, in unifying the entire Christian Church and bringing peace to the empire. The importance of this Council was illustrated in various images painted in churches, drawn on papyri, or in miniatures found in manuscripts. This was necessary because literacy was not yet widespread.
