So Paul was a Roman Catholic. Gotcha.
Again, your denominational bias is really showing.
The truth is that Paul, along with the rest of the founding fathers of the Church, were followers of Christ, members of His Church — which consists of all those who’ve been adopted into His family, and is not restricted to those who are members of the Roman Catholic denomination.
the only church present at that time was the church which they had founded...the Catholic church...there were no Lutherans, no Methodists, no Latter day Saints, no evangelical anythings
