Indeed, Abraham saw His day and rejoiced (Jn 8:56). It was said to him, "In your seed all the nations shall be blessed" (Gen 22:18). Jacob also speaks prophetically about Him who was to be born from the seed of Judah: "He shall be the expectation of the nations" (Gen 49:10).
Moses also considered the reproach of Christ greater wealth than the treasures of Egypt (Heb 11:26). Isaiah says, "Behold, the virgin shall conceive and bear" (Is 7:14). Elsewhere he says, "There shall be a shoot from Jesse, and He shall rise to rule the nations. In Him the nations shall hope" (Is 11:1).
So as not to prolong the proofs too much, it is enough to cite a few words from the Psalms: "All the families of the nations shall worship before Him" (Ps 21:28), and, "All nations shall serve Him" (Ps 71:11). Still more clearly, concerning the people of Israel and the Lord Savior, it says, "Visit this vineyard, and perfect what Thy right hand has planted, and look upon the Son whom Thou hast strengthened for Thyself" (Ps 79:15-16).
The completion of His Incarnation is shown in the following words: "Let Thy hand be upon the man of Thy right hand, and upon the Son of Man whom Thou hast strengthened for Thyself" (Ps 79:18).
Therefore, one must either say with Montanus that the patriarchs and prophets spoke in ecstasy and did not know what they were saying, or, if such an opinion is impious, since the spirit of the prophets was subject to the prophets, they certainly understood what they were saying.
But if they understood, how does Paul now affirm that what was revealed to Christ's apostles was not known to other generations? Therefore we must answer in one of two ways. First, the Apostle cautiously and meaningfully bears witness that the mystery was unknown to the sons of men, but not to the sons of God, to whom it is said, "I said, You are gods, and all of you sons of the Most High" (Ps 81:6). Thus those who had received the Spirit of adoption, among whom were the patriarchs and prophets, knew the mystery of God.
Or, if this is not accepted and seems too forced and strained, then our explanation will proceed as follows. The Apostle did not say absolutely and generally that the mystery of the Lord was wholly unknown to other generations. He said that the ancient patriarchs and prophets did not know it as it has now been revealed to His saints and apostles.
For this reason the prophet John is called greater than all the prophets (Lk 7). He personally beheld Him whom the prophets foretold, and pointed to Him with his finger, saying, "Behold the Lamb of God, behold Him who has taken away the sins of the world" (Jn 1:29).
The following words must also be interpreted according to this meaning: "Many prophets and righteous men desired to see what you see, and did not see it, and to hear what you hear, and did not hear it" (Lk 10:24). Certainly, they wanted to see and hear what they knew was to come. For if they had not known what was to come, how could they have desired what they did not know?
In the books of Kings we read that the Lord promised Solomon in a dream and said, "Because you asked this word of Me, and did not ask for many days, nor demand riches or the life of your enemies. But asked to understand and hear right judgment, behold, I have fulfilled your word and have given you a prudent and wise heart, such as none before you had, and after you none like you shall arise" (3 Kgdms 3:11).
How, then, do some suppose that the mystery was revealed to Christ's apostles but was unknown to Solomon, when the divine voice promised that Solomon would be wiser than all the apostles and, after them, the patriarchs? He himself also says of himself with full assurance: "God taught me wisdom, and I knew the understanding of the saints" (Prov 30:3).
David likewise boasts of knowing the hidden mystery, saying, "Thou hast revealed to me the unknown and secret things of Thy wisdom" (Ps 50:8). And to the one who applauded himself for wisdom, God says through the prophet, "Are you wiser than Daniel?" (Ezek 28:3).
Therefore we must either hold to the sense we established earlier, namely, that the patriarchs and prophets did not know the mystery of Christ in the same way as it has now been revealed to the apostles. It is one thing to hold something in one's hands, and another to foresee it by the Spirit.
Or we must say that, just as faces are not like faces and hearts not like hearts, so, according to the Apostle's word, there are different gifts. One has prophecy, another kinds of tongues, a third gifts of healings, another helps and governments. One is wise, another faithful. One has the ability to explain hidden things, another is content with simple faith (1 Cor 12).
For not all spoke equally, as Solomon did, about the nature of beasts, birds, and plants, so as to discourse from the cedar of Lebanon to the hyssop that sprang through the wall. For his part, Solomon may not have been as discerning as Moses concerning every kind of sacrifice and divine worship. The Lord did not speak with him face to face. Nor did he have, or understand, the beautiful arrangement of the vessels whose pattern the Lord showed Moses on the mountain (3 Kgdms 4).
Just as we must believe that the patriarchs and prophets possessed something the apostles did not possess, so, conversely, by necessity and according to the time and form of the preaching of the Gospel, the apostles possessed a clearer knowledge of the mystery of Christ. Holy men of old also knew this mystery, but not in the same way as the apostles, to whom the duty of preaching was entrusted.
What, then, is this mystery that was not revealed to other generations as it is now? It is, of course, what follows: "that the Gentiles are fellow heirs, members of the same body, and fellow partakers of the promise in Christ Jesus through the Gospel" (Eph 3:6). Of this Gospel Paul became a minister according to the gift of the grace of God, given to him according to the working of His power.
I know that the addition of the prefix "co-" in Latin makes the speech inelegant. But since it is present in Greek, and since individual words, syllables, and points in the holy Scriptures are filled with meaning, we prefer to incur criticism for word formation and composition rather than for corrupting the sense.
Therefore the Gentiles are fellow heirs of Israel, or, as seems better to us, of Christ, since our inheritance is God. This is also written elsewhere: "Heirs of God and fellow heirs with Christ" (Rom 8:17). This does not mean that some inheritance is divided among us, but that the Lord Himself is our inheritance and possession, because it is said, "The Lord is your inheritance" (Deut 18:2). Elsewhere it is said, "The Lord is my portion and my inheritance" (Ps 15:5).
"Members of the same body" means that, as in one body there are many members, such as eyes, hands, feet, ears, belly, and knees, and since they are in one body, they have their own distinctions and rejoice or suffer for one another. So also those who have believed in Christ, though they have different grace, are gathered in the one body of the Church.
In the two words mentioned above, "fellow heirs" and "members of the same body," there is already occasion to think that there is something distinct in the one body. But by his addition, "and fellow partakers of the promise in Christ Jesus," every thought of distinction is removed, because where there is fellowship, all things are wholly common.
Beautifully he adds, "Through the Gospel, of which I became a minister according to the gift of grace, which was given to me according to the working of His power" (Eph 3:7). He does this to show that this was the work of grace, not of his own merit. For he knew that he had been a persecutor and had laid waste the Church of Christ.
By such humility the sin of arrogance is completely excluded. Some accuse him of arrogance because he says that the mystery was revealed to him which had been unknown to the prophets and patriarchs. Yet the disciple of humility never spoke arrogantly. He said that the Gospel of which he was minister was not the work of his merit, but of the grace of God.
Those who suppose that the prophets did not understand their own words and spoke as though in ecstasy use this testimony to confirm their teaching. They also use another, found in many copies of the Epistle to the Romans: "Now to Him who is able to strengthen you according to my Gospel and the preaching of Christ Jesus. According to the revelation of the mystery kept silent from eternal times, but now made manifest through the prophetic Scriptures and through the coming of our Lord Jesus Christ," and so on.
To such people it is necessary to reply briefly that in past times the mystery of Christ was kept silent, not for those to whom its fulfillment had been promised, but for all the nations, to whom it was later revealed. Likewise it must be noted that the mystery of our faith could be revealed only through the prophetic Scriptures and the coming of Christ.
