A custom existed among the first generations of Christians, when faith was a bright fire that warmed more than those who kept it burning. In every house then a room was kept ready for any stranger who might ask for shelter; it was even called “the stranger’s room.” Not because these people thought they could trace something of someone they loved in the stranger who used it, not because the man or woman to whom they gave shelter reminded them of Christ, but because—plain and simple and stupendous fact—he or she was Christ.
