RCs live under the delusion that all of their theology was being espoused by the Apostles. A cursory review of the word tradition doesn’t support their claim. Nor do the contradictory claims regarding Mary.
You didn’t answer my question.
Appealing to the Bible is, by definition, appealing to the authority of people who were/are not apostles, specifically, those who decided which books the Bible consists of. This is true no matter which version of the Bible you accept. It’s unavoidable.
