Below the 33rd, the Satanic elements are only hinted at. But seriously, what other clubs threaten you with all that gnarly shit for breaking your oaths to silence? That should be the first clue that there's something off about it. Then there's the initiations with the skulls, with the daggers etc etc as you climb the degrees. Woven throughout all the while is information that, when viewed a different way, is most certainly Satanic (as in, the laws of nature are the only laws, do what thou wilt, there is no good or evil -- that is where they will guide you up the degrees).

I know you don't believe me. That's fine. Its shrouded in Christian trappings to trap members with Christian values/sensibilities at the lower degrees, and you will never find yourself invited too high without seeing into what they are actually trying to teach you. The only way Satanism could survive the last few hundred years was through the Masons and other orders/sects, which had to portray themselves as Christian to not be destroyed.

When the Masons work is done, every church will be a brothel.
