It's encouraging you're skeptical. Hopefully that means all RCs don't dismiss the OT with such delight.
I’m no newbie. I’ve been involved in numerous discussions (many of them with you, in fact)... not once have I ever seen a recognized RC apologist (as opposed to simpleton or troll) make such a ridiculous assertion. Our Faith is the one that gave you the Canon of Scripture and the key to understanding it through typology.
Just as there are members of any Faith who don’t truly understand it, you can’t rely on the post of an uncatechised Catholic to represent the Magisterium.
