I suppose if you are just wanting to discuss the history of why Councils were convened that’s one thing (and I am not 100% sure why the more recent Councils you bring up were convened and don’t have interest in commenting on it - others have anyway), that’s one thing. But if you are bringing it up to somehow to argue that Catholics “keep changing [their] [C]hurch” (your words from
post #97) , I added the big “C” and made it fit my sentence notified w/ the ] ), and that the Catholic Church is to be faulted for this alleged “innovation”, then your point proves too much.
For example, in Acts 15, the civil authority had absolutely no part in the convening of an Ecumenical Council whereas at Nicaea I, the Emperor expressed a desire for that Council to be held and made it known to the Church, to my understanding. Therefore, following your logic, the undivided Church “changed” from Acts 15 to Nicaea I. We both know that this is not so though.
