If any one wishes to know what we mean when we say that Christendom was and is one culture, or one civilization, there is a rough but plain way of putting it. It is by asking what is the most common, or rather the most commonplace, of all the uses of the word "Christian." There is, of course, the highest use of all; but it has nowadays many other uses. Sometimes a Christian means an Evangelical. Sometimes, and more recently, a Christian means a Quaker. Sometimes a Christian means a modest person who believes that he bears a resemblance to Christ. But it has long had one meaning in casual speech among common people, and it means a culture or a civilization. Ben Gunn on Treasure Island did not actually say to Jim Hawkins, "I feel myself out of touch with a certain type of civilization"; but he did say, "I haven't tasted Christian food." The old wives in a village looking at a lady with short hair and trousers do not indeed say, "We perceive a divergence between her culture and our own"; but they do say, "Why can't she dress like a Christian?" That the sentiment has thus soaked down to the simplest and even stupidest daily talk is but one evidence that Christendom was a very real thing. But it was also, as we have seen, a very localized thing, especially in the Middle Ages. And that very lively localism the Christian faith and affections encouraged led at last to an excessive and exclusive parochialism. There were rival shrines of the same saint, and a sort of duel between two statues of the same divinity. By a process it is now our difficult duty to follow, a real estrangement between European peoples began. Men began to feel that foreigners did not eat or drink like Christians, and even, when the philosophic schism came, to doubt if they were Christians.
