On the Mysteries

Contents (10 chapters)

1. 1. Introduction.
2. 2. Chapter I. St. Ambrose states that after the explanations he has already given of holy living, he will now explain the Mysteries. Then after giving his reasons for not having done so before, he explains the mystery of the opening of the ears, and shows how this was of old done by Christ Himself.
3. 3. Chapter II. What those who were to be initiated promised on entering the Church, of the witnesses to these promises, and wherefore they then turned themselves to the East.
4. 4. Chapter III. St. Ambrose points out that we must consider the divine presence and working in the water and the sacred ministers, and then brings forward many Old Testament figures of baptism.
5. 5. Chapter IV. That water does not cleanse without the Spirit is shown by the witness of John and by the very form of the administration of the sacrament. And this is also declared to be signified by the pool in the Gospel and the man who was there healed. In the same passage, too, is shown that the Holy Spirit truly descended on Christ at His baptism, and the meaning of this mystery is explained.
6. 6. Chapter V. Christ is Himself present in Baptism, so that we need not consider the person of His ministers. A brief explanation of the confession of the Trinity as usually uttered by those about to be baptized.
7. 7. Chapter VI. Why they who come forth from the laver of baptism are anointed on the head; why, too, after baptism, their feet are washed, and what sins are remitted in each case.
8. 8. Chapter VII. The washing away of sins is indicated by the white robes of the catechumens, whence the Church speaks of herself as black and comely. Angels marvel at her brightness as at that of the flesh of the Lord. Moreover, Christ Himself commended His beauty to His Spouse under many figures. The mutual affection of the one for the other is described.
9. 9. Chapter VIII. Of the mystical feast of the altar of the Lord. Lest any should think lightly of it, St. Ambrose shows that it is of higher antiquity than the sacred rites of the Jews, since it was foreshadowed in the sacrifice of Melchisedech, and far better than the manna, as being the Body of Christ.
10. 10. Chapter IX. In order that no one through observing the outward part should waver in faith, many instances are brought forward wherein the outward nature has been changed, and so it is proved that bread is made the true body of Christ. The treatise then is brought to a termination with certain remarks as to the effects of the sacrament, the disposition of the recipients, and such like.
