Yes, but do you think Christians spend much time going over old laws? My experience was mostly about bettering yourself and realizing your own sin. Sermons on philosophical issues with passages from numerous books all reflecting and supporting the main point, from different angles. I was always agnostic and absolutely loathed organized religion when I was younger but the knowledge I learned, on a philosophical humanistic level about the human condition, not even necessarily religious preaching, was invaluable, but I was lucky my church was filled with brilliant people, alot of business owners so the experience is different for everyone.
