On the Duties of the Clergy — Historical footnotes

24. Therefore, because what is useful is also just, it is just to serve Christ, Who redeemed us. They too are just who for His Name’s sake have given themselves up to death, they are unjust who have avoided it. Of them it says: What profit is there in my blood? that is: what advance has my justice made? Wherefore they also say: “Let us bind the just, for he is useless to us,” that is: he is unjust, for he complains of us, condemns and rebukes us. This could also be referred to the greed of impious men, which closely resembles treachery; as we read in the case of the traitor Judas, who in his longing for gain and his desire for money put his head into the noose of treachery and fell.

the Prophet: “Incline my heart unto Thy testimonies and not to covetousness,” that the sound of the word “useful” may not rouse in us the desire for money. Some indeed put it thus: “Incline my heart unto Thy testimonies and not to what is useful,” that is, that kind of usefulness which is always on the watch for making gains in business, and has been bent and diverted by the habits of men to the pursuit of money. For as a rule most people call that only useful which is profitable, but we are speaking of that kind of usefulness which is sought in earthly loss “that we may gain Christ,” whose gain is “godliness with contentment.” Great, too, is the gain whereby we attain to godliness, which is rich with God, not indeed in fleeting wealth, but in eternal gifts, and in which rests no uncertain trial but grace constant and unending.
