>> “Why did Jesus never point directly to Scripture?” <<
He did nothing but quote his own Tanakh almost every time he spoke.
No one “carried” Tanakh with them, they resided in the temple and the synagogues. Yeshua need not carry it because he wrote it.
Yeshua denounced all oral tradition, and held to his Torah completely.
The “scriptures” are the Tanakh. That is what Paul Peter and John called scripture, and what the Bereans used to verify the teachings of all.
Please spare us any more catholic fairy tales.
You were not there.
You make claims which can not be supported.
I was not there either of course, but all reasonable people KNOW that copies of actual Scripture were RARE until the printing press, and that MOST Christians NEVER read from actual Scripture in the early Church, they learned for an Oral Tradition.
