Luke 16:6

(de Qu. Ev. l. ii. qu. 34.) Or because out of the hundred measures of oil, he caused fifty to be written down by the debtors, and of the hundred measures of wheat, fourscore, the meaning thereof is this, that those things which every Jew performs toward the Priests and Levites should be the more abundant in the Church of Christ, that whereas they give a tenth, Christians should give a half, as Zaccheus gave of his goods, (Luke 19:8.) or at least by giving two tenths, that is, a fifth, exceed the payments of the Jews.

A cadus in Greek is a vessel containing three urns. It follows, And he said unto him, Take thy bill, and sit down quickly, and write fifty, forgiving him the half. It follows, Then said he to another, And how much owest thou? And he said, An hundred measures of wheat. A corus is made up of thirty bushels. And he said unto him, Take thy bill, and write fourscore, forgiving him a fifth part. It may be then simply taken as follows: whosoever relieves the want of a poor man, either by supplying half or a fifth part, will be blessed with the reward of his mercy.

From this we learn then, that we are not ourselves the masters, but rather the stewards of the property of others.

(ut sup.) But the wicked steward aptly contrived the remission of debts, to provide for himself an escape from his misfortunes among his fellow-servants; for it follows, I am resolved what to do, that when I am put out of the stewardship, they may receive me into their houses. For as often as a man, perceiving his end approaching, lightens by a kind deed the load of his sins, (either by forgiving a debtor his debts, or by giving abundance to the poor,) dispensing those things which are his Lord's, he conciliates to himself many friends, who will afford him before the judge a real testimony, not by words, but by the demonstration of good works, nay moreover will provide for him by their testimony a resting-place of consolation. But nothing is our own, all things are in the power of God. Hence it follows, So he called every one of his Lord's debtors unto him, and said unto the first, How much owest thou unto my Lord? And he said, A hundred casks of oil.
