You also don’t explain why you discard all Catholic teaching except that dealing with the fact of revealed truth as set out in the Bible and the compilation thereof except by pointing to that very Bible. Sorry but the Bible can’t prove itself. Unless you can prove to me that some angle dropped a nice bound volume of parchment to a human bible protestant bible worship makes no sense.
I cannot help your inability to see that it was you who asked to see something from the Bible, and now that this was provided you still object as if this is still contrary to SS, or amounts to circular reasoning. However, discerning something as being of God is both Scriptural and it is not proving the Bible by the Bible, but Scripture does show how something is judged to be of God based upon the weight of evidences external to Scripture. Both men and writings of God came to be established as being so essentially due to their unique heavenly qualities and attestation. Thus it remains that you have no argue against SS as described.
Oh?
Then neither can Rome prove itself.
