"The entire Catholic church" and "regular Catholics." Hmm. How does your Venn diagram work, that there are "regular Catholics" that aren't part of the "entire" church? The first Christians were Messianic Jews, as opposed to the Pharisee/rabbinical Jews, and of course the Sadducees, Karaites, Essenes, and non-aligned. Their biggest opposition was from other Jews calling them heretics, much like Christian denominations attacking each other.
