Even if a person had no Catholic education, and no understanding of the rubrics of the Mass, it would take a high level of toleration for silliness to sit through the ordeal of watching the barefoot dancing vestal virgins, the whirling incense pots, and the deacon sashaying aroung the altar with the Book of the Gospels.
When a Mason becomes a 33rd degree Freemason he learns who his god is, Lucifer. Freemasonry is a Luciferian doctrine. That is one reason why Freemason's are so anti-Catholic. Satan recognizes the Catholic Church to be the Church of Christ so he he has the greatest hate for it. Other denonminations are already in error so they are not as great of a threat to the devil.
