I am a Mason and would be happy to answer any questions you may have.
My father was a 32nd degree mason in both the York and Scottish rite and I have imitated his path. I believe in a Creator but am not Christian per se. Junction Guy was spot on when he said you must profess a belief in a creator but not necessarily the Christian God. When you go beyond the 3rd degree there are a lot more references to Biblical stories as alegories or parables not necessarily as historical fact. If you go the Socttish route, you will encounter the use of Jehovah in the ritual.
Due to having to sit through Biblical stories again I found some of the degrees were tough to stomach but the lessons are good regardless.
If you become a third degree Mason, there is little religious involvement except swearing under oath to God and historical references to King Solomon and the temple.
PM me or feel free to respond here with any questions you may have. Masonry is what you put into it. However, family and work are to be put first but some Masons get carried away with Masonic opportunities and roles. There is one Lodge meeting per month and one meeting of general purposes. Thus the two meeting youheard about. But then there is visiting neighbouring lodges, special fundraising events, elections, Grand Master's Gala Events. Then if you go into the York or Scottish Rite then there is at least one more meeting per month. If you hold a Chair position then there are Warden Association Events, education nights.
I could be busy every night of the week but really limit myself to the two meetings per month and the occasional fund raiser and I am just finishing my first year as Master of my Lodge.
