The T'nach may not anticipate Jesus (real or imaginary) -- or it might, but that is irrelevant. The point is that one cannot put faith in the son of man in whom there is no salvation.

Christians and their bible call Jesus the son of man, ergo the T'nach has already told them he is NOT a savior. Real or imagined, anticipated or not.
