As a Christian Mason, I know what you are saying. My family was a Masonic family, so I had no problems there. They all knew the truth, and my Mother was a 50 year member of the Eastern Star (ladies Masonic organization).
I used to go to a certain department store where the clerk noticed my Knights Templar shirt, and asked me what that was. I told him that it was the Christian branch of Masonry, and he didn't understand. We had that "of the devil" discussion many times and I shared with him the many biblical teachings that I used both in Masonry and in my Christianity. People don't always understand that Masonry is not a religion, and that Masonry encourages each of us to practice our own religion without conflict with our religious practice. We must learn to live together in "Peace and Harmony" whether we are in the lodge or without the lodge.
Good luck with your Masonic Journey - it is worth everything you put into it.
