c] there is no post crucifixion appearance of Jesus in the oldest manuscript, the Sinai Codex of Mark
d] according to the passage Jesus did not want a different set of the law for the Gentiles. The command says, "ALL NATIONS.....teaching them TO OBEY ALL I HAVE COMMANDED" If ONLY JEWS were meant to obey these laws, then why would Jesus have instructed Jews to teach people of all nations to OBEY these laws?
e] the passage quotes Jesus instructing his disciples to go about "baptizing them in the name of the Father, and of the Son, and of the Holy Ghost:" However, there is no evidence in any part of the NT that any of them baptised as Jesus instructed. So either Jesus did not give the so called "Great Commission" or if he did then his followers decided to disobey his instruction.
