The word 'pagan' is derived from the Latin term pagus, meaning 'country district.' It was used to describe people who were not Christian, Jew nor Muslim. It equates to the word heathen, which came into English via the Germanic route and means the same thing. Pagan has recently acquired a capital 'P' and seems to be a quite respectable handle nowadays.

So I would say your pageant is on safe ground if it makes no reference to any of the Big Three religions.
