Along with small changes to song lyrics and movie quotes, there seem to have been a large number of changes to ancient religious texts. The most vocal about this have been avid readers of the Christian bible, where the trinity is now in question, an Angel instead of God talked to Moses in the burning bush, oh, and there are unicorns and stuff in the bible now.
The effects on religion is by no means limited to Christianity. Changes to the Old Testament means changes in the fundamental underlying principles of Judaism, Christianity and Islam. There may well be similar changes to the Koran and the Torah, and to ancient Hindu and Buddhist writings.
As a consequence of these changes to ancient texts, religious attitudes have changed in key places towards greater tolerance within the religion, and greater harmony between religions.
