The heart is deceitful above all things, and desperately wicked: who can know it?
All Commentaries on Jeremiah 17:9 Go To Jeremiah 17
Irenaeus of Lyons
AD 202
For this reason it is said, “Who shall declare his generation?” since “he is man, and who shall recognize him?” But one to whom the Father who is in heaven has revealed him knows him, so that he understands that he who “was not born either by the will of the flesh or by the will of man” is the Son of man, that is, Christ, the Son of the living God. For I have shown from the Scriptures that no one of the children of Adam is as to everything, and absolutely, called God or named Lord. But that he is himself in his own right, beyond all people who ever lived, God, and Lord, and King eternal and the incarnate Word, proclaimed by all the prophets, the apostles and by the Spirit, may be seen by all who have attained to even a small portion of the truth. Now, the Scriptures would not have testified these things of him, if, like others, he had been a mere man. But that he had, beyond all others, in himself that pre-eminent birth that is from the most high Father, and also experienced that pre-eminent generation that is from the Virgin, the divine Scriptures do in both respects testify of him.
