sins which was to be effected by Christ, and of which those of old became partakers by protesting their faith in the Redeemer, while taking part in the figurative sacrifices.
The impediments to external worship consisted in certain bodily uncleannesses; which were considered in the first place as existing in man, and consequently in other animals also, and in man's clothes, dwelling-place, and vessels. In man himself uncleanness was considered as arising partly from himself and partly from contact with unclean things. Anything proceeding from man was reputed unclean that was already subject to corruption, or exposed thereto: and consequently since death is a kind of corruption, the human corpse was considered unclean. In like manner, since leprosy arises from corruption of the humors, which break out externally and infect other persons, therefore were lepers also considered unclean; and, again, women suffering from a flow of blood, whether from weakness, or from nature (either at the monthly course or at the time of conception); and, for the same reason, men were reputed unclean if they suffered from a flow of seed, whether due to weakness, to nocturnal pollution, or to sexual intercourse. Because every humor issuing from man in the aforesaid ways involves some unclean infection. Again, man contracted uncleanness by touching any unclean thing whatever.
Now there was both a literal and a figurative reason for these uncleannesses. The literal reason was taken from the reverence due to those things that belong to the divine worship: both because men are not wont, when unclean, to touch precious things: and in order that by rarely approaching sacred things they might have greater respect for them. For since man could seldom avoid all the aforesaid uncleannesses, the result was that men could seldom approach to touch things belonging to the worship of God, so that when they did approach, they did so with greater reverence and humility. Moreover, in some of these the literal reason was that men should not be kept away from worshipping God through fear of coming in contact with lepers and others similarly afflicted with loathsome and contagious diseases. In others, again, the reason was to avoid idolatrous worship: because in their sacrificial rites the Gentiles sometimes employed human blood and seed. All these bodily uncleannesses were purified either by the mere sprinkling of water, or, in the case of those which were more grievous, by some sacrifice of expiation for the sin which was the occasion of the uncleanness in question.
The figurative reason for these uncleannesses was that they were figures of various sins. For the uncleanness of any corpse signifies the uncleanness of sin, which is the death of the soul. The uncleanness of leprosy betokened the uncleanness of heretical doctrine: both because heretical doctrine is contagious just as leprosy is, and because no doctrine is so false as not to have some truth mingled with error, just as on the surface of a leprous body one may distinguish the healthy parts from those that are infected. The uncleanness of a woman suffering from a flow of blood denotes the uncleanness of idolatry, on account of the blood which is offered up. The uncleanness of the man who has suffered seminal loss signifies the uncleanness of empty words, for "the seed is the word of God." The uncleanness of sexual intercourse and of the woman in child-birth signifies the uncleanness of original sin. The uncleanness of the woman in her periods signifies the uncleanness of a mind that is sensualized by pleasure. Speaking generally, the uncleanness contracted by touching an unclean thing denotes the uncleanness arising from consent in another's sin, according to 2 Cor. 6:17: "Go out from among them, and be ye separate . . . and touch not the unclean thing."
