You do realize the catechism is not the Bible, don't you?
Where is Sola Scriptura in the Bible?
This Mediator [Jesus Christ], having spoken what He judged sufficient first by the prophets, then by His own lips, and afterwards by the apostles, has besides produced the Scripture which is called canonical, which has paramount authority, and to which we yield assent in all matters of which we ought not to be ignorant, and yet cannot know of ourselves.
For the Biblical reference, see 2 Thessalonians 2:15:
With all these things in mind, dear brothers, stand firm and keep a strong grip on the truth that we taught you in our letters and during the time we were with you.
So St. Augustine and St. Paul both call on the Divine and ultimate truth of the Bible. Sola Scriptura.
Still waiting for you to give any reference to the succession of the Pope as Biblical! Or his ability to speak ex cathedra.
Where is the word Trinity in the Bible?
The word is not. The concept is. Can you say the same about the Pope or ex cathedra writs from the Pope?
You do realize that the Catechism is larded with footnotes, don't you?
So St. Augustine and St. Paul both call on the Divine...
Truth of the Bible? Absolutely.
But:
...and ultimate....
I didn't see any hint of "ultimate" in there.
Further, Sts. Augustine and Paul do NOT say Scripture ONLY.
Finally, since by its own definition sola Scriptura must be defined by Scripture alone, St. Augustine is out of bounds.
I mean, out of bounds for the sola Scriptura crowd, anyway.

False. St. Paul did not know that his letters would be named Scripture. He wanted the people under his authority as bishop to follow his theological commands, as all bishops do.

It has as much direct and indirect evidence.
