St Ireneus on the Incarnation

Whence then is the substance of the first formed man? From the Will and the Wisdom of God, and from the virgin earth. For God had not sent rain, the Scripture says, upon the earth, before man was made; and there was no man to till the earth. From this, then, whilst it was still virgin, God took dust of the earth and formed the man, the beginning of mankind. So then the Lord, summing up afresh this man, took the same dispensation of entry into flesh, being born from the Virgin by the Will and the Wisdom of God; that He also should show forth the likeness of Adam’s entry into flesh and there should be that which was written in the beginning,man after the image and likeness of God.
And just as through a disobedient virgin man was stricken down and fell into death, so through the Virgin who was obedient to the Word of God man was reanimated and received life. For the Lord came to seek again the sheep that was lost; and man it was that was lost: and for this cause there was not made some other formation, but in that same which had its descent from Adam He preserved the likeness of the (first) formation. For it was necessary that Adam should be summed up in Christ, that mortality might be swallowed up and overwhelmed by immortality; and Eve summed up in Mary, that a virgin should be a virgin’s intercessor, and by a virgin’s obedience undo and put away the disobedience of a virgin.
