And Jesus never spoke a word about Paul. If Paul is so important to Christians then shouldn’t at least one prophet [have] predicted anything about him, like we have predictions about Jesus and Mohammad in the Old Testament?
My two cents
I’m not exactly convinced by that premise (i.e. Paul’s words only have validity if he was prophesied in the Old Testament). The viewpoint implies that prophecy trumps inspiration. I don’t believe that viewpoint was held during the formation of the New Testament canon; inspiration (in and of itself) was sufficient.
If prophecy is ultimate, then all of the Old Testament prophets may also need to have been prophesied (in the Torah), but I don’t think that was the case, especially if the authorship of certain books is unknown or disputed.
Regarding the linkage of Mohammad with prophecies in Deuteronomy, I thought that the Christian interpretation of that verse precedes the Muslim interpretation. I may have missed it, but I don’t recall the Church Fathers being unsure of how to interpret that verse, then feeling settled on it once Islam emerged.
