Sorry but I don't know anything about a secret rapture.
You may not know anything about it, but that is precisely what your copy pasta is arguing for. Did you not read it?
And please......annual observance of the Feast of Tabernacles on pain of Messianic sanctions? Seriously? But why stop there? Let's not forget the 3rd temple of Ezekiel 40-48 with its sin offerings, etc. Truly, there is no end to human folly when it must defend the so-called 'literal' hermeneutic (in relation to the Messianic prophecies of the OT) at any and all cost.
