“And I said unto him: Deniest thou the Christ who shall come? And he said: If there should be a Christ, I would not deny him; but I know that there is no Christ, neither has been, nor ever will be. And I said unto him: Believest thou the scriptures? And he said, Yea. And I said unto him: Then ye do not understand them; for they truly testify of Christ. Behold, I say unto you that none of the prophets have written, nor prophesied, save they have spoken concerning this Christ.” In Jacob 7, Sherem denies Christ, but then approves the scriptures. The scriptures clearly talk that Christ will come. So, Sherem either made a mistake or misunderstood the scriptures. But, the number of times the scriptures mention that and how clear they do are hard to all misinterpret. I think that Sherem was just trying to trap Jacob in a lie, but that plan backfired.
