Exodus 12:22

62. But when the student of the Holy Scriptures, prepared in the way I have indicated, shall enter upon his investigations, let him constantly meditate upon that saying of the apostle’s, “Knowledge puffeth up, but charity edifieth.” For so he will feel that, whatever may be the riches he brings with him out of Egypt, yet unless he has kept the passover, he cannot be safe. Now Christ is our passover sacrificed for us, and there is nothing the sacrifice of Christ more clearly teaches us than the call which He himself addresses to those whom He sees toiling in Egypt under Pharaoh: “Come unto me, all ye that labor and are heavy laden, and I will give you rest. Take my yoke upon you, and learn of me; for I am meek and lowly in heart: and ye shall find rest unto your souls. …

2. “And the Jews’ passover was nigh at hand.” The Jews wished to have that feast-day crimsoned with the blood of the Lord. On it that Lamb was slain, who hath consecrated it as a feast-day for us by His own blood. There was a plot among the Jews about slaying Jesus: and He, who had come from heaven to suffer, wished to draw near to the place of His suffering, because the hour of His passion was at hand. Therefore “many went out of the country up to Jerusalem before the passover, to sanctify themselves.” The Jews did so in accordance with the command of the Lord delivered by holy Moses in the law, that on the feast-day of the passover all should assemble from every part of the land, and be sanctified in celebrating the services of the day. But that celebration was a shadow of the future. …

2. Yet, though your greatness terrifies me, your kindness attracts me. From the priest I demand the safe-keeping of the victim, from the shepherd the protection due to the sheep. Away with all that is overweening; let the state of Roman majesty withdraw. My words are spoken to the successor of the fisherman, to the disciple of the cross. As I follow no leader save Christ, so I communicate with none but your blessedness, that is with the chair of Peter. For this, I know, is the rock on which the church is built! This is the house where alone the paschal lamb can be rightly eaten. This is the ark of Noah, and he who is not found in it shall perish when the flood prevails. …

After this Paula went a short distance down the hill to the tower of Edar, that is ‘of the flock,’ near which Jacob fed his flocks, and where the shepherds keeping watch by night were privileged to hear the words: “Glory to God in the highest and on earth peace, goodwill toward men.” While they were keeping their sheep they found the Lamb of God; whose fleece bright and clean was made wet with the dew of heaven when it was dry upon all the earth beside, and whose blood when sprinkled on the doorposts drove off the destroyer of Egypt and took away the sins of the world.

XV. But if you would fortify yourself beforehand with the Seal, and secure yourself for the future with the best and strongest of all aids, being signed both in body and in soul with the unction, as Israel was of old with that blood and unction of the firstborn at night that guarded him, what then can happen to you, and what has been wrought out for you? Listen to the Proverbs. “If thou sittest, he says, thou shalt be without fear; and if thou sleepest, thy sleep shall be sweet.” And listen to David giving thee the good news, “Thou shalt not be afraid for the terror by night, for mischance or noonday demon.” This, even while you live, will greatly contribute to your sense of safety (for a sheep that is sealed is not easily snared, but that which is unmarked is an easy prey to thieves), and at your death a fortunate shroud, more precious than gold, more magnificent than a sepulchre, more …

A proof of this is found in the Circumcision on the eighth day, which was a sort of typical seal, and was conferred on children before they had the use of reason. And so is the anointing of the doorposts, which preserved the firstborn, though applied to things which had no consciousness. But in respect of others I give my advice to wait till the end of the third year, or a little more or less, when they may be able to listen and to answer something about the Sacrament; that, even though they do not perfectly understand it, yet at any rate they may know the outlines; and then to sanctify them in soul and body with the great sacrament of our consecration. …

34. After this white robes were given to you as a sign that you were putting off the covering of sins, and putting on the chaste veil of innocence, of which the prophet said: “Thou shalt sprinkle me with hyssop and I shall be cleansed, Thou shalt wash me and I shall be made whiter than snow.” For he who is baptized is seen to be purified both according to the Law and according to the Gospel: according to the Law, because Moses sprinkled the blood of the lamb with a bunch of hyssop; according to the Gospel, because Christ’s garments were white as snow, when in the Gospel He showed forth the glory of His Resurrection. He, then, whose guilt is remitted is made whiter than snow. So that God said by Isaiah: “Though your sins be as scarlet, I will make them white as snow.”
