The Tanach, Yah'shua preached from Deuteronomy and Isaiah and .... Paul and Peter and Jude and James all preached from the Tanach ! You are right that the Roman "church" rejected What they were reading in the first century was the Holy Word of G-d.

the Holy Word of G-d: the Tanach and Yah'shua the Jewish Messiah
