You must believe in god to be a mason, not any specific god and you are not allowed to push your religeon on other masons. None are superior to others in their views.
My grandfather was a mason and i have his masonic bible it has a lot of old Egyptian stuff in it as well as the christian bible. I have some ideas about this but no facts why this is important to them.
All I know about joining the masons is "ask one to be one" is their motto. And they have to approve you, you must be of good character, though i have no idea what the criteria is.
