Friend, the only thing you need to do is know that the Church condemns Freemasonry in toto. Have nothing to do with it, call it the pagan filth that it is, do not keep familiar association with anyone involved, and one day, when Freemasonry is unmasked as the damnable demonic cult that it is, you will have guarded your soul against it and will be proven right for having rejected it.
Much holier men and women than I have run like mad from the evils of paganism, the occult and heretical movements. I am far too ignorant and spiritually weak to do anything but imitate their examples.
You would do very well to do likewise.
Holy Mother of God, pray for us who have recourse to thee.
St. Anthony of Padua, hammer of heretics, terror of Hell, pray for us.
Most Sacred Heart of Jesus, ever present in the Sacrament of the altar, have mercy on us.
