And as Daniel1212 said so well, to make such an assertion would, by default, mean that we would ALL be under the authority of the Seat of Moses, for the Jews were the ones who put together the OT which was written almost entirely by Jews. The only way the RCC can even make such a statement is by laying claim to all the writers of Holy Scripture as all being members of the Catholic Church. But we know very well that they were part of the body of Christ, the church, which could be called the catholic church because it was the universal church of all believers. That church, BTW, which we are ALL members of who have received Jesus Christ. But the Roman Catholic Church, which did not come to head the Christian world until the fourth century, has NO claim to authorship NOR to control over its interpretation, much less authority over all Christians. Instead, they desire to be as the Pharisees were in Jesus' day and we know how well that went over with him.
The thing about delusion is the blind cannot see truth that's soooo obvious to everyone else. We know the Jews were the very source of the Old Testament and bringing it together....and Rome had nothing whatsoever to do with that.
And of course we did not receive Jesus by eating a cracker...And that's the only way the Catholics receive the Christ...
By the bible definition they are not even Christians yet they still claim that THEY are the church...
Ignorance with hubris...
