You are probably going to get some heated answers to this question.
You can clearly answer "yes" when you are asked at your interview "Do you believe in a Supreme Being?" No further information is required so don't say any more than that. When you are initiated, and when you take higher degrees, you are required to take an Obligation on the Volume of the Sacred Law. This is usually the Bible although certain other sacred texts are allowed for members of various faiths. Provided that you are happy to take Obligations on the Bible there is no problem. If you aren't, or if you feel uncomfortable with a theistic approach, involving prayers to the Great Architect, then Freemasonry isn't suitable for you.
