I've read that and it seems to be written out of ignorance.. its also seems to be written out of fear that 'gasp' people would take it unto themselves to question their authority.. which I see through like a pane of glass. The fact is that free masonry doesn't do pretty much all they claim it does... so its written out of fear of the unknown.
Anyhow, if you look at the works of Free Masonry, they dwarf any 'christian' denomination in the world, except for possibly the RCC.
They say you will know Christians by their love and works... and those denominations are severely lacking.
Anyhow, you are free to associate with anyone you chose... as am I.
