Apple, where I come from, bible study is performed by a group of people who study the bible literally as written, it has nothing to do with Christianity, we call "Jehovah witnesses", they use the old testimony, don't think that by attending that meeting, you will have an idea about Christianity, it’s a sect, not a religion. They meet to read the bible, and explain it without going into spirituality and stuff... Their main objective is to attract you, they do not believe in Jesus as we Christians do.

Anyhow, I believe I went into too much details, it’s up to you to accept them or not. Also, people are free in their believes, I don't consider that we should express it through gadgets, or crosses, or ... Just pray, and believe.
