THIS letter contains a mystical explanation of the statement in Exodus xxiv.6. that Moses put half the blood of the sacrifices into basons and poured half on the altar.

AMBROSE TO SIMPLICIANUS, GREETING.

1. YOU were perplexed, you tell me, when reading that Moses, after offering sacrifice and the immolation of salutary victims to the Lord, Exod. xxiv.6. put half of the blood in basons, and sprinkled half on the altar, to know what could be the purport of this. But why need you doubt and inquire of me, when for the sake of the faith, and of acquiring Divine knowledge, you have traversed the whole world, and night and day have devoted the whole time of your life to constant reading? Thus with your keen intellect you have embraced all the objects of the understanding, and are wont to prove as concerns even the books of philosophy, how far they deviate from the truth, many of them being so futile that the words of their writers perished sooner than their life.

2. But since gathering words, like money, is of great profit, and great increase is thereby obtained for the general good of trade, I cannot refrain from mentioning how wonderful is that division of the blood. For part of it seems to signify the moral, and part the mystical discipline of wisdom. That part which is put into basons is moral, that which is sprinkled on the altar is mystical; in that by the Divine gift and a certain inspiration it is instilled into men’s minds, that the sentiments they conceive of God may be suitable and full of faith.

3. Moreover, they who have spoken of His majesty, and of heavenly things, whether apostles or holy prophets, have only dared to speak of such things as were shewn them by revelation. Hence Paul has testified in his Epistle that he was 2 Cor. xii.4. caught up into Paradise, and heard words which it is not lawful for a man to utter; Stephen also Acts vii.55. saw the heavens opened, and Jesus standing on the right hand of God, and the Prophet David saw Him Ps. cx.1. sitting on His right hand. And what shall I say of Moses, of whom the Scripture says that Deut. xxxiv. 10,11. there arose not such a prophet since in Israel, who knew the Lord face to face, in all the signs and the wonders which he did in the land of Egypt.

4. The mystical part therefore is offered to God, Who by the brightness of the Divine Wisdom, Whose Father and Parent He is, quickens the vigour of the soul, and enlightens the mind. But the Wisdom of God is Christ, on Whose breast John lay, that from that secret source of wisdom he might be known to have imbibed Divine mysteries. He himself, conscious of his gift, has recorded this, for he dreaded to claim for himself, and to ascribe to his own genius that which he had received. The Lord also said to the Apostles, opening their mouths, S. John xx.22. Receive ye the Holy Ghost, whereby He declared that He is the same Who said to Moses, Exod. iv.12. I will open thy mouth, and teach thee what thou shalt say. Wherefore this wisdom, divine, unspeakable, unadulterated and incorruptible, pours her grace into the minds of her saints, and discloses to them knowledge that they may behold her glory.

5. But that is the discipline of moral wisdom which is poured into basons, and is taken and drank from them. The basons therefore are the organs of the senses. The basons are the two eyes, the ears, the nose, the mouth and other parts suitable to this function; for the eyes are the recipients and ministers of sight, the ears of hearing, the nose of smell, the mouth of taste, and so with the rest. Into these basons that Word in Whom is the Headship of the priestly and prophetic office poured the half of His blood; that He might quicken and animate the irrational parts of our nature, and endow them with reason.

6. Again, having rehearsed and proclaimed the precepts of the Law to the people, and being about to explain the meaning of that mystical ark of the testimony, and of the candlestick, and of the censers, he slew victims, and offered sacrifice, sprinkling half of the blood on the sacred altar, and putting half in basons.

7. A division therefore is made between that mystical or divine and moral wisdom. For the ????? is a divider of souls and of virtues: the ????? is the Heb. iv.12. Word of God, quick and powerful, which pierces and penetrates even to the dividing asunder of the soul, and which also distinguishes and divides virtues, whose minister, Moses, by the division of the blood, distinguished the kinds of virtue.

8. And forasmuch as nothing is so emphatically declared in the Law as Christ’s Advent, or prefigured as His Passion, consider whether this be not the saving victim which God the Word offered by Himself, and sacrificed in His own body. For first both in the Gospel and also in the Law He taught us moral discipline, and manifested it in His own patience and in very act and deed, transfusing into our lives and senses, as if into basons, the very substance and marrow as it were of wisdom, and quickening thereby men’s minds to be a seed-plot of virtue, and instructed in piety, and then, drawing near the altar, He poured out the blood of His offering.

9. Should you choose then to understand it thus, the sense is pious; the interpretation also which follows that of Solomon is, if you prefer it, equally concordant, namely, that whereas the prophet Moses put the blood into basons, this is the same blood whereof it is written that Prov. ix.2. Wisdom hath mingled her wine, bidding men to forsake foolishness, and seek after understanding. From the bason then we drink wisdom, discipline, understanding, correction, amendment of life, regulation of habits and counsels, the grace of piety, increase of virtue, a fountain of plenty.

10. But by this sprinkling the blood on the Altar you may understand the cleansing of the world, the remission of all sins. For He sprinkles that blood on the Altar as a Victim to atone for the sins of many. For the Victim is a Lamb, but a Lamb not of irrational nature but of divine power, of Which it is said, S. John i.29. Behold the Lamb of God which taketh away the sin of the world. For not only has He cleansed with His blood the sins of all men, but has also gifted them with divine power. Does not He seem to you to have indeed shed his blood, Ib. xix.34. from Whose side blood and water flowed over the very altar of his Passion?

Farewell; love me as you do, with the affection of a parent.
