You may have meant, if they are well catechized. The Catholic Church, as we know it, was founded some centuries later, and not by Jesus at all.
If you want to state that each pope was the holy successor to St Peter, and upheld the office, then perhaps we should step through the more notorious ones. I think we can dig up slave ownership, murder on a large scale, embezzlement, sexual exploitation, violation of vows in many ways, persecution of Jews, persecution of gays… It goes on and on. A case could easily be made that this sort of behavior has been normal to the papacy for some centuries. It is all fairly well documents.
Even if we allow your point, then the question we must ask is: would Jesus condone the behavior of today’s Catholic Church? Would Jesus have approved of the horrific antisemitism advocated by the papacy for centuries? Bringing it to the present, would Jesus have protected and facilitated child molesters? Would Jesus have approved of attempts to avoid supporting the victims of molestation and secretive coverups, the evasion of responsibility? Or, would Jesus have advocated moral leadership, and compassion for the victims? I hope that the answer is obvious.
Would you say that the Catholic Church, over the centuries, and today, has been an honest and true representative of the teachings of Christ? I believe that a well informed person must conclude that it is not.
