My uncle was a born-again Christian. When he became a 33rd degree Mason, something very bad in Freemasonry scared him, and he sort of dropped out. He has gone home to be with the Lord, and I have no idea or hint as to what frightened him.
He seemed to enjoy his Freemason membership prior to that
last step, encouraging me in my high school years to think about Demolay. (We had a very active chapter at my high school.) He would say, “Now I can’t ask you to join.” But you could tell that he had a fond wish that my Dad and I would get involved with Freemasonry. Not so in his last years.
He probably found out who they really serve.
Because no one can ask you to join. You have to be the one to ask.
We call it 'joining of your won free will and accord'.
