That is a logical fallacy.
I believe in Christ. Christ says of the Church “he who hears you hears me,” so because I believe in Christ, I believe the Church. The Church says that the documents given in the canon (list) issued by the Church are to be believed, and so, because I believe Christ, I must believe the Church on the issue. You may disagree with my reason for believing in scripture, you may disagree with Augustine’s, but it is an accurate description of the act of belief involved, and not a fallacy.
That’s circular logic which is illogical.
*In the beginning was the Word, and the Word was with God, and the Word was God.*
The Roman Catholic Church neither predates these words nor does it validate them with its existence. What kind of vanity is it that one would hold their church above God?
