Another begging the question fallacious assertion. It remains that distinctive Catholic teachings are not manifest in the only wholly God-inspired, substantive, authoritative record of what the NT church believed (which is Scripture, in particular Acts through Revelation, which best shows how the NT church understood the gospels)
Thus ultimately requiring reliance on oral tradition and the novel and unScriptural premise of ensured perpetual magisterial veracity, which itself appeals to the former, under which then tradition and history can only authoritatively assuredly mean what she says, if she says so herself. Thus RC teaching is supposed to be the supreme law, under the premise that it cannot contradict Scripture, according to her.
Creepy if true! LOL
My point was merely to introduce to them the Holy Spirit as a/the source for posting, inasmuch as that seems to be novel to them. How nice and lovely heaven's conversations will be, when our personal foibles are behind us and His Spirit permeates our free will.
