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
On the one hand the name Jesus refers to the man who was assumed by the Word, the man born from the Virgin. … Then again it refers to the Word of God: “for to us there is one Lord Jesus Christ, through whom are all things” … When Paul says “as truth is in Jesus,” he is speaking of the temple of God in which God the Word dwells. The Word was made flesh and dwelt among us. God is the Word. As life dwells in him, so he also is life. … In this same way the Son too may be called the truth, and truth may be said to dwell in him. In saying this we do not separate God the Word from the humanity he assumed. The man he assumed is not someone else. According to our understanding of certain passages we give different titles to him whom we believe to be the one Son of Man and Son of God, both before and after the virgin birth…. In none of the patriarchs, in none of the prophets, in none of the apostles did truth reside as it did in Jesus. For others know in part and prophesy in part and see “as through a glass darkly.” In Jesus alone the truth of God has appeared. He confidently asserts “I am the truth.” .
