He indicates that he has been shown the revelation of the mystery of God, about which he says that he has written briefly, that is, precisely, according to their capacity to comprehend the wisdom of the apostle in the mystery of Christ.

Clement Of Alexandria

AD 215
Rightly, then, the apostle says that it was by revelation that he knew the mystery: "As I wrote afore in few words, according as ye are able to understand my knowledge in the mystery of Christ.". Rightly, therefore, the divine apostle says, "By revelation the mystery was made known to me (as I wrote before in brief, in accordance with which, when ye read, ye may understand my knowledge in the mystery of Christ), which in other ages was not made known to the sons of men, as it is now revealed to His holy apostles and prophets."

Paul indicates that this mystery was made known to him through revelation. From this passage it is evident that a Christian, and a very excellent Christian at that, can be brought into being solely by grace…. Nevertheless, the power of God dispenses grace in many ways. Others come to faith by teaching, wherein by a legitimate training process and through the commandments of the Savior a person is reborn through the Spirit and water, so as to receive the spirit of Christ, in a teaching process that is mediated from human beings and through human beings.

This revelation seems to have regarded principally three things: 1. The redemption and justification of man by Jesus; 2. the vocation of the Gentiles; and thirdly, a positive command to announce the gospel to them. He speaks particularly of the second and third. (Estius) Made known to me by revelation, and to the other apostles and prophets. (Witham)

I ask, was not Paul himself, the wonderful, he that was so versed in the law, he that was brought up at the feet of Gamaliel according to the most perfect manner, was not he saved by grace? With good reason too does he call this a mystery, for a mystery it is, to raise the Gentiles in a moment to a higher rank than the Jews. As I wrote afore, says he, in few words, i.e., briefly,
