Pray for him and fast and offer him up to our Blessed Mother for his enlightenment. Masonry is insidious, covert and dark. But the good news is that Mama Mary will always crush the head of satan.
Freemasonry is especially dangerous because of how they are able to conceal their occultism. What many people don;t realize is that satanists are all about denying the spiritual nature of the human person and seek to reduce them to the flesh and promote materialism. Interestingy enough, totalitarianism has many of these same ideologies.
By the way, does anyone know if there is a connection between the Freemasons and the Bilderberg Group?
