Next to the image of Lazarus, or rather the composite image of the two Lazaruses, the picture of leprosy that filled the imagination was that of the thirteenth and fourteenth chapters of Leviticus. That picture is even more composite than the other, and for leprosy in the strict sense it is absolutely misleading. The word translated “leprosy” is a generic term for various communicable maladies, most of which were curable within a definite period, sometimes no longer than a week. It rested with the skill of the priesthood to discriminate between the forms of communicable disease, and to prescribe the appropriate ceremonial treatment for each; the people had one common name for them all, and beyond that they were in the hands of their priests, who knew quite well what they were about. The Christian Church dealt with all those archaic institutions of an Eastern people in a child-like spirit of verbal or literal interpretation, doubtless finding the greater part of them a meaningless jargon. But some verses would touch the imagination and call up a real and vivid picture, such verses, for example, as the following: “And the leper in whom the plague is, his clothes shall be rent, and his head bare, and he shall put a covering upon his upper lip, and shall cry, Unclean, unclean. All the days wherein the plague shall be in him he shall be defiled; he is unclean; he shall dwell alone; without the camp shall his habitation be.” Even in that comparatively plain direction, the obvious suggestion that the unclean person would not always be unclean, and that there was a term to his stay outside the camp, would go for little in reading the scripture. The medieval religious world took those parts of the Jewish teaching that appealed to their apprehension, and applied them to the circumstances of their own time with as much of zeal as the common sense of the community would permit. We have clear evidence of the effect of the Levitical teaching about “leprosy” upon English practice in the ordinances of the St Albans leper hospital of St Julian, which will be given in the sequel. The Medieval Religious Sentiment towards Lepers.
