While debating with a protestant he says the Catholic Church got it wrong, there are only 66 books in the old testament, instead of the 73 that Catholics have.
He says Jesus Himself affirmed the Jewish canon of the Old Testament. The Lord Jesus affirmed the Law, the Prophets, and the Writings and all that was written in them. (Matt. 15:16, Mark 7:13, Luke 3:2, 5:1, etc)
My understanding is that Jesus time the old testament Bible for the Jews included the 73 books which catholics have. Did the apostoles and Jesus, referenced it, or the “extra” books mentioned?
