***when he presents a reference from the Bible with an authentic interpretation.***
Ah, how do we know it was authentic? I saw no citation of the Magisterium.
So private interpretation of Scripture is okie dokie for a Catholic layperson when there is no official pronouncement of the Magisterium and the interpretation fits Catholic dogma?
Is there a Catholic Bible with the obvious passages in red and the passages where there is an official Magisterium interpretation in blue?
Would the liturgy for the Tridentine Mass be printed in blue?
I made no reference to obvious passages vs. difficult ones. None of them contradict Church teachings, because they are Church teachings.
As for the so-called Tridentine Mass, you will not find it in the Bible, in blue or red ink. You will find the Bible in it, though, and quite a bit of it at that. You will also find that it doesn't contradict scripture in neither jot nor tittle.
