Fourth Century Christianity

This list is based on that of Ramsay MacMullen, Voting About God in Early Church Councils, (New Haven 2006), pp. 2-4. We have, however, added and subtracted from the original list to make it more accurate and complete. The website also features Friedrich Maassens’ list of Early Councils in Geschichte der Quellen und der Literatur des canonischen Rechts im Abendlande.

 

Roman numerals have been placed before the Ecumenical Councils to indicate their numbering.
