If so be that you have heard him, and have been taught by him, as the truth is in Jesus:
All Commentaries on Ephesians 4:21 Go To Ephesians 4
Jerome
AD 420
If all who seem to hear Christ did indeed hear him, the apostle would never had said this to the Ephesians. They were those to whom he had already revealed the promises of Christ. Why would he then say conditionally: “if indeed you have heard him?” To know Christ is the same thing already as knowing virtue. To hear of Christ rightly is the same as being attentive to all the virtues: wisdom, justice, temperance, fortitude and the other names by which Christ is called. Therefore if anyone has indeed heard and learned Christ, he would not be living “in the futility of his mind” nor “be darkened in understanding” nor be “alienated from the life of God.” He would already have practical knowledge, since his ignorance would have been dispelled, his darkness illuminated and every blindness lifted from the eyes of his heart. .
