“And since these “other things” were not written down by His apostles, we have ZERO knowledge of them.”
But the imagination can fill in the gaps with worship of designated saints and their supposed relics, mythical stories of Mary’s mother, etc.
“But Rome, in its manic hubris, concocts fictitious events and tells its gullible followers that its many superstitions come under the rubric of “other things” which were neither written down nor taught by Christ and the early church.”
Quite so!
"And I know such a man, (whether in the body, or out of the body, I cannot tell: God knoweth;) How that he was caught up in to paradise, and heard unspeakable words, which it is not lawful for a man to utter." 2 Cor. 12:3,4.
Can you imagine the religious system Protestants could build if they decided to use these words of Paul to build a false religion? First, they would need to declare themselves infallible. Then declare that the "not lawful" does not apply to them since they are infallible. From that point on, it's any man's decision what they wanted Paul to hear. False Traditions and doctrines of men would flood the churches, until the Bible could no longer be the absolute truth, scripture interpretation would have to be IMPLICITLY stated, and of course, we would need ONE MAN in charge, to "lead' the fold and assure us that we are the only true third heaven paradise church on earth.
