[one Lord one faith one baptism]

“everybody was considered Catholic”

you can only be considered Catholic if you hold the Catholic FAITH.

many departed from this Faith in the 16th century over Baptism, the Eucharist, Predestination, the Bible, Apostolic Succession, etc etc.

[WILLIALAL]

“you can only be considered Catholic if you hold the Catholic FAITH.”

Again, the initial premise was about the term Catholic, not the Roman Catholic church. There is a different meaning and history.
