Which in other ages was not made known unto the sons of men, as it is now revealed unto his holy apostles and prophets by the Spirit;
All Commentaries on Ephesians 3:5 Go To Ephesians 3
John Chrysostom
AD 407
Tell me then, what part did the prophets not fully grasp? How can Christ say later that Moses and the prophets wrote “these things about me”? … What he is saying is that the expectation of Christ was not revealed to everyone. It “was not made known to the sons of men in other generations as it has now been revealed to his holy apostles and prophets by the Spirit.” Peter, if he had not been guided by the Spirit, would never have gone to the Gentiles. … The prophets therefore spoke but did not have complete knowledge at the time. They did not even have complete knowledge after they heard the gospel, which far exceeds human reason and common expectations. .
