I am involved in a discussion concerning the Council of Chalcedon and Canon 28. Per Michael Whelton's book, "Popes and Patriarchs", he states," Canon 28 was formally received into the canonical collection of the Eastern Church at the Council in Trullo in 690. It was finally accepted in the Western Church in 1274 at the Second Council of Lyons."
The other party in this discussion disputes that the Western Church or Rome ever accepted Canon 28. Further research on my part has drawn a complete blank and there is no mention of Canon 28 at the Second Council of Lyons.
Can anyone set the record straight?
