Although the path may be different, the conclusion you arrived at seems to be the same as that arrived at by the (Catholic) Councils of Carthage that had taken place in the early 4th century.
I am not familiar with them...nor about that happening...assuming it was a meeting of catholic leadership of some sort at that time. Over the centuries they have held many such meetings in determing the course they believe the church should take on doctrine and issues...but I am not catholic so these are not familiar to me for the most part.
