The First '''Council of Nicaea''', the first [[ecumenical council]] recognized by Christian churches (other than the [[Council of Jerusalem]] recorded in the [[New Testament]]), was summoned by Emperor [[Constantine]] in A.D. 325 in order to address disunity in the Church stemming from [[Arianism]]. It was the first time Christians could be called together from across the [[Roman Empire]] as it had been illegal before then and incurred persecutions leading to death. | The First '''Council of Nicaea''', the first [[ecumenical council]] recognized by Christian churches (other than the [[Council of Jerusalem]] recorded in the [[New Testament]]), was summoned by Emperor [[Constantine]] in A.D. 325 in order to address disunity in the Church stemming from [[Arianism]].
