Not satanic, but also not Christian.

to be a blue lodge Mason you only have to believe in a supreme being, not a particular religion, and the only reason that the Catholics are against Masonry is that they have secrets in the rituals (very minor but identifying, like passwords) that you are only supposed to discuss with brother masons and priests are not allowed to become brother Masons, and priests don’t want you to have secrets from them. that is also why Catholics started the Knights of Columbus.
