In the Catholic Church we have Sacred Scripture and Apostolic Tradition. Is there a similar Jewish Tradition in our religion? For example, The Talmud or other such writings. What can they tell us about the Old Testament?
Our canon of the OT is completely Jewish Sacred Tradition… Jesus and the Apostles used the Septuagint, which is why we use it today, but there is not an inspired list of what books belong in the OT.
The Seat of Moses is another Jewish Sacred Tradition, not mentioned anywhere in the OT, yet affirmed by Christ. Jesus transferred the teaching authority to His One Church.
Our understanding about the sacrament of matrimony and the evil of abortion also comes from Jewish sacred tradition. I supposed it would be a long list if we were to delve into it.
Just one more, though, that relates to the dispute over the body of Moses, mentioned in the NT, ,but nowhere in the OT.
Jude 9-10
9 But when the archangel Michael contended with the devil and disputed about the body of Moses, he did not dare to bring a condemnation of slander against him, but said, “The Lord rebuke you!”
Oh and that reminds me of another one.
2 Tim 3:8-9
8 As Jannes and Jambres opposed Moses, so these people, of corrupt mind and counterfeit faith, also oppose the truth.
Although the story is contained in the OT, the names of the people were not written. They came down through sacred tradition, just like we have the names of Mary’s parents.
