May you give bread; that is to say, let us have nourishment from our just efforts. If your profit does not belong to others, if your income is not the result of another’s tears, if no one is hungry because you are full, if no one groans because of your abundance, such then is the bread of God, the fruit of justice, the ear of the corn of peace, undefiled by being mixed with the seed of tares. But if you cultivate what belongs to others and fill your eyes with injustice, confirming your unjust gains with written documents, then you may indeed say to God: ‘Give bread’, but another will hear this cry of yours, not God. One who pursues righteousness receives bread from God, whereas the man who cultivates injustice is fed by the inventor of injustice.
Saint Gregory of Nyssa, On the Lord’s Prayer, 4, quoted in The Wisdom of the Greek Fathers compiled by Father Andrew Louth (Lion Publishing, 1997), 35.
