You are making yourself clear enough. Again, are you arguing that,
1. SS means that only the Bible can be used in determining faith and practice, and,
2. that because Rome is the instrument and stewards of Holy Writ (which promises guidance to the church) then the Roman Catholic church is uniquely the assuredly infallible interpreter of it, and supreme authority on Truth (versus the Scriptures) and that,
3. she is necessary for assurance of truth?
Thanks.
-—1. SS means that only the Bible can be used in determining faith and practice, and,-—
Yes. It’s the final authority in matters of faith.
-—2. that because Rome is the instrument and stewards of Holy Writ (which promises guidance to the church) then the Roman Catholic church is uniquely the assuredly infallible interpreter of it, and supreme authority on Truth (versus the Scriptures) and that,-—
This is a somewhat circular argument, and not my position.
The divinely inspired nature of Scripture and the divinely protected teaching authority of the Church can be demonstrated with high probability by initially regarding the Scriptures simply as an historical document.

This proof uses the Bible (as an historical document) to show that Christ claimed to found a Church that would last forever. History demonstrates the existence of a unique earthly organization, possessing a non-contradictory body of teaching, existing from the time of Christ. Christ’s astounding, unprecedented prophecy regarding His Church was true.
One can then assume with reasonable certainty that Christ is Who He claimed to be, and that His Church exists on earth. Since Christ is Truth, His Church cannot teach error. His Church proposes the Bible as inspired. Therefore, we can trust the Bible to be inspired.
3. she is necessary for assurance of truth?
Yes, with respect to the truths of faith and morals, granting that moral truths can also be known with certainty through the natural law.
Thank you for charitable taking the time to understand my position!
