Stones sounds much like the hymn Stricken, Smitten, and Afflicted: http://www.youtube.com/watch?v=qr7-fgX1CB0 Because they are in fact the same song in a sense. The "Avatar" in the ultima series referred to as the "Prophet" on many occasions and if you dig deeper into the lore you can in fact determine that the avatar is basically christ portrayed through the game in the form of the avatar. The whole thing is basically borrowed from the bible if you will with new elements mixed in. This is pretty common in games actually and many including chrono trigger use this formula.
