“You also try to equate the non-unity of personal beliefs and practices with diunity in the teachings of the Catholic Church. There is really only ONE set of real, true, official Catholic teachings. How individual Catholics relate to those official teachings is merely a reflection of their own choices, but does NOT reflect disunity in the Catholic teachings themselves.”
Just how effective is teaching that people ignore? Or scorn?
Didn't many people ignore and scorn the sacred teachings directly from Jesus Christ, and didn't they also mock Him about those sacred teachings?
