"Put Christ back into Christmas" is now a well-worn cliché. Sincere people tell us that a Christian should observe "the church calendar" such as Christmas and Easter in a Christian way rather than the commercial way of the world. The problem is that this overlooks a preliminary question; are these festivals right at all? There can be no Christian way of doing what is wrong in itself. There is no Christian way of robbing banks or vandalizing bus shelters, so we cannot speak of the right spirit with which to observe these things unless they are legitimate to begin with. There was no right way to worship the golden calf, even though Aaron called it "a feast to the Lord" (Exodus 32/5).
