I have edited and uploaded the Nicene Creed. This version is as framed in the year 325, according to the text contained in Socrates’ Ecclesiastical History, and I made footnotes where it is different in the texts from the Acts of the Council of Chalcedon, and St. Athanasius. An expanded version later came out of Constantinople, but this is the original Nicene Creed. The later version also eliminated the Anathema found at the end of the original.
This document of the Nicene Creed is a pdf, and alternates between the Greek text and the English translation.
