The answer
Our Church celebrates Emperor Constantine and calls him the great for his role in ending the persecution of the Christians and promoting Christianity. Emperor Constantine was very much involved in the Church's affairs, had churches built and made legislations based on Christian beliefs and morals. The Nicene Creed was first adopted at the first ecumenical council convened by Emperor Constantine in Nicea in 325 AD. Constantine made Christianity the official state religion of the Roman Empire (Edict of Milan, early in 313).Answered by His Eminence Metropolitan Youssef (opens in a new tab)
