"Jesus was a marginal Jew". According to what? Jesus was God himself. His virgin birth was prophesied by Isaiah. Jesus could perform miracles. He healed people. Gave sight to blind. Rose the dead back to life. There are hundreds of prophecies that cover Jesus birth, death, resurrection, and return as a king who rules forever.
