Chapter 50.
The Levites ought to be utterly free from all earthly desires. What their virtues should be on the Apostle's own showing, and how great their purity must be. Also what their dignity and duty is, for the carrying out of which the chief virtues are necessary. He states that these were not unknown to the philosophers, but that they erred in their order. Some are by their nature in accordance with duty, which yet on account of what accompanies them become contrary to duty. From whence he gathers what gifts the office of the Levites demands. To conclude, he adds an exposition of Moses' words when blessing the tribe of Levi.
255. If, then, in the Gospel of the Lord the people themselves were taught and led to despise riches, how much more ought ye Levites no longer to be bound down by earthly desires. For your portion is God. For when their earthly possessions were portioned out by Moses to the people of our fathers, the Lord suffered not the Levites to have a share in that earthly possession, for He Himself would be the strength of their inheritance. Wherefore David says: “The Lord is the portion of mine inheritance and of my cup.” Whence we get the name “Levite,” which means: “Himself is mine,” or “Himself for me.” Great, then, is his honour, that God should say of him: Himself is Mine. Or, as was said to Peter about the piece of money found in the fish's mouth: “Give to them for Me and for you.” Wherefore the Apostle, when he said: “A bishop should be sober, modest, of good behaviour, given to hospitality, apt to teach, not covetous, nor a brawler, one that rules well his own house,” also added: “Likewise must the deacons be grave, not double-tongued, not given to much wine, not greedy of filthy lucre, holding the mystery of the faith in a pure conscience. And let them also first be proved, and so let them serve, being found blameless.”
256. We note how much is required of us. The minister of the Lord should abstain from wine, so that he may be upheld by the good witness not only of the faithful but also by those who are without. For it is right that the witness to our acts and works should be the opinion of the public at large, that the office be not disgraced. Thus he who sees the minister of the altar adorned with suitable virtues may praise their Author, and reverence the Lord Who has such servants. The praise of the Lord sounds forth where there is a pure possession and an innocent rule at home.
257. But what shall I say about chastity, when only one and no second union is allowed? As regards marriage, the law is, not to marry again, nor to seek union with another wife. It seems strange to many why impediment should be caused by a second marriage entered on before baptism, so as to prevent election to the clerical office, and to the reception of the gift of ordination; seeing that even crimes are not wont to stand in the way, if they have been put away in the sacrament of baptism. But we must learn, that in baptism sin can be forgiven, but law cannot be abolished. In the case of marriage there is no sin, but there is a law. Whatever sin there is can be put away, whatever law there is cannot be laid aside in marriage. How could he exhort to widowhood who himself had married more than once?
258. But ye know that the ministerial office must be kept pure and unspotted, and must not be defiled by conjugal intercourse; ye know this, I say, who have received the gifts of the sacred ministry, with pure bodies, and unspoilt modesty, and without ever having enjoyed conjugal intercourse. I am mentioning this, because in some out-of-the-way places, when they enter on the ministry, or even when they become priests, they have begotten children. They defend this on the ground of old custom, when, as it happened, the sacrifice was offered up at long intervals. However, even the people had to be purified two or three days beforehand, so as to come clean to the sacrifice, as we read in the Old Testament. They even used to wash their clothes. If such regard was paid in what was only the figure, how much ought it to be shown in the reality! Learn then, Priest and Levite, what it means to wash your clothes. You must have a pure body wherewith to offer up the sacraments. If the people were forbidden to approach their victim unless they washed their clothes, do you, while foul in heart and body, dare to make supplication for others? Do you dare to make an offering for them?
259. The duty of the Levites is no light one, for the Lord says of them: “Behold I have taken the Levites from among the children of Israel, instead of every first-born that opens the matrix among the children of Israel. These shall be their redemption, and the Levites shall be Mine. For I hallowed unto Me all the first-born in the land of Egypt.” We know that the Levites are not reckoned among the rest, but are preferred before all, for they are chosen out of all, and are sanctified like the firstfruits and the firstlings which belong to the Lord, since the payment of vows and redemption for sin are offered by them. “You shall not receive them,” He says, “among the children of Israel, but you shall appoint the Levites over the tabernacle of testimony, and over all the vessels thereof, and over all things that belong to it. They shall bear the tabernacle and all the vessels thereof, and they shall minister in it, and shall encamp round about the tabernacle. And when the tabernacle sets forward the Levites shall take it down, and when the camp is pitched they shall set up the tabernacle again. And the stranger that comes near shall surely be put to death.”
260. You, then, art chosen out of the whole number of the children of Israel, regarded as the firstfruits of the sacred offerings, set over the tabernacle so as to keep guard in the camp of holiness and faith, to which if a stranger approach, he shall surely die. You are placed there to watch over the ark of the covenant. All do not see the depths of the mysteries, for they are hid from the Levites, lest they should see who ought not to see, and they who cannot serve should take it up. Moses, indeed, saw the circumcision of the Spirit, but veiled it, so as to give circumcision only in an outward sign. He saw the unleavened bread of sincerity and truth; he saw the sufferings of the Lord, but he veiled the unleavened bread of truth in the material unleavened bread, he veiled the sufferings of the Lord in the sacrifice of a lamb or a calf. Good Levites have ever preserved the mystery entrusted to them under the protection of their own faith, and yet do you think little of what is entrusted to you? First, you shall see the deep things of God, which needs wisdom. Next, you must keep watch for the people; this requires justice. You must defend the camp and guard the tabernacle, which needs fortitude. You must show yourself continent and sober, and this needs temperance.
261. These chief virtues, they who are without have recognized, but they considered that the order resting on society was higher than that resting on wisdom; though wisdom is the foundation, and justice the building which cannot stand unless it have a foundation. The foundation is Christ.
262. First stands faith, which is a sign of wisdom, as Solomon says, in following his father: “The fear of the Lord is the beginning of wisdom.” And the law says: “You shall love the Lord your God, you shall love your neighbour.” It is a noble thing to do one's kindnesses and duties towards the whole of the human race. But it is ever most seemly that you should give to God the most precious thing you have, that is, your mind, for you have nothing better than that. When you have paid your debt to your Creator, then you may labour for men, to show them kindness, and to give help; then you may assist the needy with money, or by some duty, or some service that lies in the way of your ministry; by money to support him; by paying a debt, so as to free him that is bound; by undertaking a duty, so as to take charge of a trust, which he fears to lose, who has put it by in trust.
