If it keeps going, what would mean it couldn't continue to Mo-hammed, or Joe Smith?
“...once one has accepted that prophecy is possible after the end of the Old Testament.”
Quite a Jesuitical banana peel there, as we Catholics say.
The advent, ministry, and sacrifice of Jesus was the fulfillment and completion of the Old Testament prophecies which foretold the Messiah, as professed by we Christians.
The New Testament describes all of the above. After that, that’s all there is, there isn’t any more.
OBTW, for those who believe otherwise, I give you fourteen centuries of the murderous rampages of the followers of Mohammed who study the Koran.
Won’t even mention believers in the Book of Mormon. They don’t kill those who either refuse to convert or leave after converting. Everyone here says Mormons whom they know are the nicest people. I fully agree.
The question is not, is it possible for men to continue to prophesy for God? The question is, were these men true prophets of God?
If a man is a true prophet from God EVERY prophecy he makes in the name of God will come true. Google Joseph Smith false prophesies and you will see that he clearly doesn't pass God's test for a true prophet.
