If any one wants to hold the end of a chain which really goes back to the heathen mysteries, he had better take hold of a festoon of flowers at Easter or a string of sausages at Christmas. Everything else in the modern world is of Christian origin, even everything that seems most anti-Christian. The French Revolution is of Christian origin. The newspaper is of Christian origin. The anarchists are of Christian origin. Physical science is of Christian origin. The attack on Christianity is of Christian origin. There is one thing, and one thing only, in existence at the present day which can in any sense accurately be said to be of pagan origin, and that is Christianity.
