Other than the Apostles’ Creed, the Nicene Creed is likely the most universally accepted and recognized statements of the Christian faith. The Nicene Creed was first adopted in A.D. 325 at the Council of Nicea. The Roman Emperor Constantine had convened the Council of Nicea in an attempt to unify the Christian church with one doctrine, especially on the issues of the Trinity and the deity and humanity of Jesus Christ.
