Your quotes about uncircumcised nations keeping the Passover as spiritualized in Yeshua assumes the New Testament is true. It is not. Have you actually compared the Tanakh prophetic proof texts of the NT with them in the Tanakh and looked at the full context of the Tanakh? They are ridiculously taken out of context. Plus the irreconcilable contradictions between the Four Gospels, like the Last Supper you just mentioned, which the Synoptics say was on the Passover but in John it says instead it was before and that Yeshua died on the Passover.
