Chapter V.—A Passage of Jeremiah Examined.
And here I may adduce the prophet Jeremiah as a trustworthy and lucid witness, who speaks thus: "Then I went down to the potter's house; and, behold, he wrought a work on the wheels. And the vessel that he made of clay was marred in the hand of the potter: so he made it again another vessel, as seemed good to the potter to make it."  For when Adam, having been formed out of clay, was still soft and moist, and not yet, like a tile, made hard and incorruptible, sin ruined him, flowing and dropping down upon him like water. And therefore God, moistening him afresh and forming anew the same clay to His honour, having first hardened and fixed it in the Virgin's womb, and united and mixed it with the Word, brought it forth into life no longer soft and broken; lest, being overflowed again by streams of corruption from without, it should become soft, and perish as the Lord in His teaching shows in the parable of the finding of the sheep; where my Lord says to those standing by, "What man of you, having an hundred sheep, if he lose one of them, doth not leave the ninety and nine in the wilderness, and go after that which is lost until he find it? and when he hath found it, he layeth it on his shoulders rejoicing; and when he cometh home, he calleth together his friends and neighbours, saying unto them, Rejoice with me; for I have found my sheep which was lost."
 Jeremiah 18:3, 4.
