And those that did know it, such as the prophets, had it revealed to them very obscurely, and by means of symbols. People's New Testament 3:5 Which. The mystery. In other ages was not made known unto the sons of men. It was in past ages hidden from men, but now revealed by the Spirit to apostles and prophets. Not the old Hebrew prophets, but the prophets in the church.

Wesley's Notes 3:5 Which in other - In former, ages was not so clearly or fully made known to the sons of men - To any man, no, not to Ezekiel, so often styled, son of man; nor to any of the ancient prophets.

Making known by revelation is the source of making known by preaching [Bengel]. The former was vouchsafed only to the prophets, in order that they might make known the truth so revealed to men in general. unto the sons of men-men in their state by birth, as contrasted with those illuminated "by the Spirit" (Greek, "IN the Spirit," compare Re 1:10), Mt 16:17. as-The mystery of the call of the Gentiles (of which Paul speaks here) was not unknown to the Old Testament prophets (Isa 56:6, 7; 49:6). But they did not know it with the same explicit distinctness "As" it has been now known (Ac 10:19, 20; 11:18-21). They probably did not know that the Gentiles were to be admitted without circumcision or that they were to be on a level with the Jews in partaking of the grace of God.

The epithet, "holy," marks the special consecration of the New Testament "prophets" (who are here meant) by the Spirit, compared with which even the Old Testament prophets were but "sons of men" (Eze 2:3, and elsewhere).

All the gracious offers of the gospel, and the joyful tidings it contains, come from the rich grace of God; it is the great means by which the Spirit works grace in the souls of men. The mystery, is that secret, hidden purpose of salvation through Christ. This was not so fully and clearly shown in the ages before Christ, as unto the prophets of the New Testament. This was the great truth made known to the apostle, that God would call the Gentiles to salvation by faith in Christ. An effectual working of Divine power attends the gifts of Divine grace. As God appointed Paul to the office, so he qualified him for it. |
