Different Versions of the Nicene Creed Over the Years
As stated earlier, the original creed was taken up in 325 AD, and the occasion was the First Council of Nicaea. At that, time the conflict was regarding the origin of the creed. The Coptic Church argued that it was authored by the then head of the Church, Athanasius, but then Adolf Harnack said that the Eusebius of Caesarea brought it to the Council.
