No, I didn’t mean to say that the Jerusalem Council was an Ecumenical Council (to my understanding it was a proto- Ecumenical Council, though not considered the 1st as that is Nicaea 1.)
However, with that being said, both of us obviously believe the Jerusalem Council in Acts 15 is relevant to our points, or else why would we have both brought it up in the context of discussing Ecumenical Councils, right? So, my point still stands. And I was not saying that local councils aren’t called for by an emperor, rather, I was saying that the emperor was involved in at least some way at Nicaea I, whereas that was not the case in Acts 15; the civil authority had no part there in any way. So, using your same standard that you are using to apparently find fault with the Catholic Church for the “change” you claim was made in convening an Ecumenical Council not for the purpose of combatting a heresy (for arguments sake I am conceding that point, although I am not saying’s correct), you should find fault with the early Church for making an “innovation” if you are being consistent, as I see it.
