LOL If you dont understand the things going on in Acts 19 and then follow through to the council of Ephesus to watch what happened to appease the citizens of Ephesus by including their worship of the goddess Diana in Christian worship you need to study a little more. It was at the council of Ephesus where the queen of heaven was incorporated into Christian worship. Then read in Revelation where the church in Ephesus is still combining pagan worship with Christian.
In Acts 19 we learn that St. Paul spent three months teaching in Ephesus"
< "And he entered the synagogue and continued speaking out boldly for three months, reasoning and persuading them about the kingdom of God." - Acts 19:8
Do you think Paul spent three months in a vain repetition of Scripture that had not yet been written or that all of what Paul had to say during these three months has been completely captured in Scripture?
For the record, the Council of Ephesus was held in 431 at the Church of Mary. It was convened to address the issue of the Nestorian heresy. Apparently some of our more extreme Protestant brothers and sisters re not content to attack Christianity with the heresies of the 16th century, they now want to destroy its roots by reopening the heresies already dealt with by the Early Church Fathers.
