Augustine of Hippo

For this reason, charity, which has more regard for the common good than for its own, is said “not to seek the things that are its own.…” Hence, this charity is practiced now in the good works of love, by which it reaches out to give aid in whatever direction it can, and this is its breadth. It bears adversity with longsuffering, and perseveres in what it holds as true, and this is its length. But it does all this in order to attain eternal life which is promised to it on high, and this is its height. This charity, indeed, is hidden in the place where we are founded and, so to speak, rooted in depth. Hence we do not search into the reasons for God’s will, by whose grace we are saved. This has come “not by the works of justice which we have done but according to his mercy.” “For of his own will he has begotten us by the word of truth,” and this will of his is hidden.

Nevertheless, after the apostle had said in such instruction and advice: “Now such persons we charge and exhort in the Lord Jesus Christ that they work quietly and eat their own bread,” he was mindful of such needs of the holy persons who, although they would obey his commands to work quietly and eat their own bread, would, for many reasons, lack some provision of such necessary commodities. Hence, with foresight he added immediately: “But you, brothers, do not grow tired of well-doing,” so that those who had the means of furnishing sustenance to the servants of God would not grow careless in this respect. Furthermore, when in writing to Titus he said: “Help Zenas the lawyer and Apollos on their way, taking care that nothing be wanting to them.” He continued thus, in order to show why nothing should be lacking in their regard: “And let the people also learn to excel in good works, in order to meet cases of necessity, that they may not be unfruitful.”
