DH brought up today that he and one of his friends were thinking of becoming Free Masons. I really don't know anything about it except that my grandfather is in it. I always thought it was more of a Christian organization so I was a bit confused as to why DH wanted to join. I was flipping through the little booklet thing he brought home, but I still don't know much about it. One of the requirements to join is to believe in a Supreme Being, which DH has already said he will lie about if he decides to join up.
Can anyone tell me about it?
