The First Ecumenical Council, also known as the Council of Nicaea, took place in 325 AD in the city of Nicaea, located in present-day Turkey. Convened by the Roman Emperor Constantine the Great, the council aimed to address divisions within the early Christian church, particularly concerning the nature of Jesus Christ and his relationship to God the Father. One of the key outcomes of the council was the formulation of the Nicene Creed, which established a unified statement of Christian faith. The council also addressed various other issues, including the date of Easter and the role of bishops, helping to shape the future of Christianity.
