Just so we're all on the same page here, obviously from the Catholic point of view we don't belong to a "denomination erected by flesh beings" but to the Society, or Body, or Church, established and headed by Christ.
It has been my experience after 30+ years of interaction with Catholic inlaws what is claimed and what is practiced. I have been told the program of who is who and what is what. But the program has some big glitches because of what is thrown in the trash basket, completely ignored as if 'flesh beings' have that authority. The 'church' was NEVER intended to be the object of worship, or any flesh beings including Mary.
