Though while he lived he blessed his soul: and men will praise you, when you do well for yourself.

AD 430
7. Let your love observe: "For his soul shall be blessed in his life" (ver. 18). As long as he lived he did well for himself. This all men say, but say falsely. It is a blessing from the mind of the blesser, not from the truth itself. For what sayest thou? Because he ate and drank, because he did what he chose, because he feasted sumptuously, therefore he did well with himself. I say, he did ill for himself. Not I say, but Christ. He did ill for himself. For that rich man, when he feasted sumptuously every day, was supposed to do well with himself: but when he began to burn in hell, then that which was supposed to be well was found to be ill. For what he had eaten with men above, he digested in hell beneath. Unrighteousness I mean, brethren, on which he used to feast. He used to eat costly banquets with the mouth of flesh, with his heart's mouth he used to eat unrighteousness. What he ate with his heart's mouth with men above, this he digested amid those punishments in the places beneath. And verily he had eaten for a time, he digested ill for everlasting. Is then unrighteousness eaten? perhaps some one saith: what is it that he saith? Unrighteousness eaten? It is not I that say: hear the Scripture: "As a sour grape is vexation to the teeth, and smoke to the eyes, so is unrighteousness to them that use it." For he that shall have eaten unrighteousness, that is, he that shall have had unrighteousness wilfully, shall not be able to eat righteousness. For righteousness is bread. Who is bread? "I am the living bread which came down from heaven." Himself is the bread of our heart. ...Is then even righteousness eaten? If it were not eaten, the Lord would not have said, "Blessed are they which do hunger and thirst after righteousness." Therefore "since his soul shall be blessed in life," in life it "shall" be blessed, in death it shall be tormented. ...
8. "He shall confess to Thee, when Thou shalt have done him good." Be not of such sort, brethren: see ye how that to this end we say these words, to this end we sing, to this end we treat, to this end toil-do not these things. Your business doth prove you: sometimes in your business ye hear the truth, and ye blaspheme. The Church ye blaspheme. Wherefore? Because ye are Christians. "If so it be, I betake myself to Donatus's party: I will be a heathen." Wherefore? Because thou hast eaten bread, and the teeth are in pain. When thou sawest the bread itself, thou didst praise; thou beginnest to eat, and the teeth are in pain; that is, when thou wast hearing the Word of God thou didst praise: when it is said to thee, "Do this," thou blasphemest: do not so ill: say this, "The bread is good, but I cannot eat it." But now if thou seest with the eyes, thou praisest: when thou beginnest to close the teeth thou sayest, "Bad is this bread, and like him that made it." So it cometh to pass that thou confessest to God, when God doeth thee good and thou liest when thou singest, "I will alway bless God, His praise is ever in my mouth." How alway? If alway gain, alway He is blessed if sometime there is loss, He is not blessed, but blasphemed. Forsooth thou blessest alway, forsooth His praise is ever in thy mouth! Thou wilt be such as just now he describeth: "He will confess to Thee, when Thou shalt have done him good."
