Can [fill in the name of the religion] be a Mason?
The only religious requirement is that candidates believe in the Supreme Being. If you can in good faith profess a belief in the Supreme Being, you are eligible to be a Mason. No atheists will ever knowingly be made a Mason. There are Christian (Catholic, Protestant), Mormon, Jewish, and Muslim Masons. It would be tedious and pointless to go into a religion-by-religion (and then denomination-by-denomination) discussion. The key points to remember are the requirement of belief in the supreme being and the fact that Masonry is a fraternity, not a religion.
