In the first place it is clear, that the first man who was formed out of the earth was made up both of earth and heaven; but because he did not continue uncorrupt, but despised the commandment of God, fleeing from the most excellent part, namely, from heaven, he gave himself up wholly as a slave to the earth, the denser and heavier element. In the second place, if any one burns with a desire of virtue, which makes the soul immortal, he, beyond all question, attains to a heavenly inheritance; but because he was covetous of pleasure, by which spiritual death is engendered, he again gives himself over a second time to the earth, on which account it is said to him, "Dust thou art, and unto dust shalt thou return;" therefore the earth, as it is the beginning of a wicked and depraved man, so also it is his end; but heaven is the beginning and end of him who is endowed with virtue.
