Well, if there is no difference than surely you can show from scripture the source for all of the RCC teachings. I would appreciate the scripture for the assumption of Mary first.
Actually I can’t even believe you had the audacity to post such a statement.
>> Without the Catholic Church’s teaching authority, we would not know with certainty which purported books of Scripture are authentic.<<
Catholics really need to give that meme up. God also used an ass, Judas, Pharaohs, and many others in error or opposition to Him to accomplish His purposes.
And the premise that recognizing truth and writings as being inspired of God means such should be submitted to in all other writings would have required the apostles to submit to Jewish magisterium.
