So as not to fly a false flag, I am not a chr*stian (though I used to be). I am a Noachide who regards the idea of a non-literal "spiritual messiah" as one of the most harmful ideas that has ever come into existence.
Well, we have to respectfully disagree on that. An earthly Messiah, ruling over the earth, is essentially what the Jewish-Zealots believed during the time of Christ. Judas, was influenced by this Jewish Group, as opposed to the Pharisees and Saduccees. When Judas realized that Christ was not interested in throwing out the Roman empire and establishing and earthly temporal Kingdom, this started Judas on the way to betrayal of Christ.
