The idea that the “church” was some unified body with everyone in proper subjection to the primacy of Rome before the schismatic heretic from Germany forever ruined the perfect unity.... that fiction is so ridiculous as to be laughable.
It is propaganda, not history.
Anyone with an elementary knowledge of Christian history knows the Catholic Church was the ONE, TRUE, FAITH, started by Christ himself. All your ancestors for over 1,500 years after Christ’s death, unless they were buddists, muslim or some other eastern religion, were CATHOLICS. Are they all burning in the pits of hell for following that “false” religion.
