[Campion]

None of the Disciples were Catholics, they were Jews. They lived as Jews and died as Jews.

All of the Apostles were baptized, all of them were ordained (at the Last Supper), and all of them died as Jewish Christians. And since the only Christian Church in existence was one, holy, catholic, and apostolic, they died as Jewish Catholic Christians.

They were not Roman Catholic in the slightest degree. No pope. No worship of Mary, etc.
