To say "Roman Catholic" is mispaced historically. The Church was "Catholic," tout court. It was only after the 16th Century that the term "Roman Catholic" gained any currency: there was a party of Anglicans who liked to call themselves "Anglo-Catholics," and they launched the correlative term, "Roman Catholics."--- to pin on the Catholics, who called themselves Catholic.
The Anglicans in England also called the Catholics "The Italian Mission." These terms were meant to be put-downs. That's not necessarily true now, but it was then.
And Msgr. Pope (the author here) doesn't speak of "Roman" Catholic, but just of "Catholic," meaning the universal Church.
Since we’re being so technically precise, i.e., the council being held at Jerusalem not Rome, the term “Catholic” is an anachronism also. The word “Catholic” is not in Acts 15.
Yes, we all know the council wasn’t a rosary bead counting, Mary idolatry “Roman Catholic” one, but the ones who call themselves “Roman Catholics” here on the RF never draw that distinction, they leave everyone with the impression that when we read Acts 15 we are to believe it is their Papist institution that is being represented there.
