From a reader:
Recently I spoke with someone, who said Catholicism and Freemasonry would be compatible. I don’t really believe this. What’s the teachong of the Church about this matter?
Catholics may not be Masons or belong to masonic organizations. That’s it.
As Leo XIII wrote in 1892 “Christianity and Freemasonry are essentially irreconcilable, so that enrolment in one means separation from the other.”
