Tertullian

Thus he wished us to understand that the man who is changed from his former carnal state to the whiteness of faith (which the world considers a blemish and a stain) and who is completely renewed is clean. He is no longer spotted, no longer mottled with both the old and the new.

But if [in a case of leprosy] after its rehabilitation and transformation, the priest again observes in that same house any of the old pocks or stains, may he pronounce it unclean and order its timbers and its stones and its whole structure to be torn down and cast forth into an unclean place. This is a type of the man, body and soul, who is transformed after baptism, that is to say, after the entrance of the priest, and then takes up once more the scabrous contaminations of the flesh. He is cast forth outside the city into an unclean place. That is to say, he is “given over to Satan for the destruction of the flesh.”

May I offer, moreover, an interpretation of the two goats which were presented on “the great day of atonement”? Do they not also prefigure the two natures of Christ? They were of like size and very similar in appearance, owing to the Lord’s identity of aspect. He is not to come in any other form. He had to be recognized by those by whom he was also wounded and pierced. One of these goats was bound with scarlet and driven by the people out of the camp into the wilderness, amid cursing, and spitting, and pulling and piercing, being thus marked with all the signs of the Lord’s own passion. The other, by being offered up for sins and given to the priests of the temple for meat, afforded proofs of his second appearance, when (after all sins have been expiated) the priests of the spiritual temple, that is, the church, are to enjoy the flesh, as it were, of the Lord’s own grace. The rest will deport from salvation without tasting it.

For this reason, in order to root out the materials of idolatry, God’s law proclaims, “You shall not make an idol”; and by adding, “Nor the likeness of any thing that is in heaven or in the earth or in the sea,” it utterly forbade such crafts to the servants of God. Enoch had anticipated this law when he prophesied that the demons and the spirits of the rebellious angels would turn to idolatry every element and property of the universe, everything which heaven and sea and earth contain, to be consecrated as a god against God. So it is that human error worships everything but the very Creator of everything. Their images are idols; the consecration of images is idolatry. Whatever sin idolatry commits must be put down to all the makers of all the idols.
