New Testament writers Paul, Peter, John and the author of Hebrews make hospitality a Scriptural command, in fact, a duty. Why was this considered so important? What does it have to do with Christianity? The first Christians viewed themselves as part of a worldwide brotherhood and they knew they were a persecuted minority in a hostile world. "Little pockets of early Christians survived," writes C.S. Lewis, "because they cared exclusively for the love of the brethren and stopped their ears to the opinion of the Pagan society all round them."
