That's just it. What possible kind of prayer can anyone come up with that isn't going to possibly going to offend someone? If you mention Jesus, you'll offend non-Christians, if you say God instead of Gods, you could offend Hindus and pantheists and pagans. If you refer to God as a "he", you offend the feminists. If you even say "God" or "gods" you'll offend the atheists and agnostics ---and if you say anything about God being good, you'll offend the Satanists.
