Amen bro. My question would be, where does all the false catholic doctrine come from? Nimrod?
Just do a Google search on the biographies of Clement of Alexandria, Justin Martyr, Irenaeus, Eusebius of Caesarea, Origen of Alexandria, and out of them the Bishop of Hippo, Augustine, who made sure the Cathological formula became the religious organ of the Roman State.
You can count on the fact that their errors came from the roots of making priests the subordinates of the religious power structure, with the ordinary "lay" people taking the big hit in this fiasco.
That's my opinion. All this was present even in Paul's time, of which he wrote to the people ogf Galatia. You will not in that epistle he was not boosting any other Gospel than the one given to him by revelation from the Lord Jesus Christ. Especially not the one being lived out by Simon bar Jona, raising problems in Paul's own home sending church of Antioch.
