That's not what he said. He said sola Scriptura is not in the Scriptures. The slogan "sola Scriptura" is a traditionnnnnnnn of mannnnnnnnnnnnn.
I'm throwin' tinsel at ya! Duck!
The use of scripture as the basis of faith is pointed to in the scriptures. The use of oral traditions is GENERALLY NOT.
Jesus taught from the scriptures and rebuked Satan with them. Peter said Paul's writings are scripture. Luke wrote to teach Theophilus the truth to be differentiated from the oral teachings. Yes, there are some positive mentions of traditions but those are few and far between. Even your church teaches that the Scriptures are inspired and complete. They just do not use them for anything other than verse picking to defend their authority. Notice which verses, not chapters or books, but verses the RCC has infallible interpretation for.
Anyone willing to take a crack at Luke 1 or the meaning of the word Magnify in the Magnificat? Still looking for any takers...I guess I need to make that my tagline...
