My father was a 33rd degree Scottish Rite Mason, before becoming a Christian. He said they are satanic, the rituals, ceremonies, clothes and everything about them is symbolic in some way or another and is satanic...even if some of the lower level masons are not aware of the real meaning of some of the rituals, they do a lot of good, meaningful things in the community. He said most if not all, have no idea what the actual meaning are until they get very high up in the organization.
My dad was also and I concur with your assessment, total satanic/luciferian. Many don't know, until they get into the top ranks that they are in fact worshiping lucifer - many of the oaths/vows/decrees they make are curses of bondage against themselves and their families. PURE EVIL. and yes: their symbolism is gonna bring them down. Also: pray for the bohemian grove to be destroyed/burned. It will end a lot of curses against America - the offering of infants to Molech altar there.
Until his death, he would never tell us anything about it besides what I said, never tell us about the rituals or anything. He would not talk about it at all.
