Who said Noachides don't believe in the Messiah? We believe in his coming just as surely as to Orthodox Jews. What kind of idiotic statement is this implying that one has to accept chr*stianity to look forward to the coming of the promised messiah???
Chr*stianity can be true only in one of two ways: either 1) the Nazarene fulfilled all the messianic prophecies "symbolically" rather than literally, or 2) he fulfilled only some of the prophecies and will finish the job at the "second coming." This second school of thought insists that it is everyone's duty to accept him as messiah even though he is only halfway through his job. Duh.
Only one religion in all history was not founded by a human being: Judaism. Even its chr*stian opponents admit it was founded by G-d and that it was the true religion at one time. Every other religion under the sun was founded by a human being (even if you insist one of those human beings was "gxd," has vechalilah). In all of world history only Judaism was publicly established by the Omnipresent G-d speaking to an entire people without any human mediation whatsoever.
PS: Don't tell me to read the nt. I've read it. I used to be a chr*stian.
