Yet the Apostles in scripture make it clear that the word of God is not contained only in scripture but also is handed down by word of mouth.
***“So then, brothers and sisters, stand firm and hold fast to the teachings we passed on to you, whether by word of mouth or by letter.” 2 thes 2:15
scripture says these teachings have been handed done throughout the ages to church leaders
***" And the things you have heard me say in the presence of many witnesses entrust to reliable people who will also be qualified to teach others." 2 tim. 2:2 ***
the Apostles also make it clear that deriving doctrine on your own through scripture is dangerous and can send you to hell.
" He (Paul) writes the same way in all his letters, speaking in them of these matters. His letters contain some things that are hard to understand, which ignorant and unstable people distort, as they do the other Scriptures, to their own destruction." 2nd Peter 3:16
So scripture says that there are teachings not in scripture, and these teachings have been handed done to church leaders. these church leaders are the ones to interpret scripture not individuals. Sounds an awful lot like the Catholic church to me.
Were do you think you will get these teachings that were handed down by word of mouth and are not in scripture? The church that’s been there from the Beginning (the Catholic church) or the church that wasn’t (all others)
