I acknowledge, indeed, that there is not enjoined upon us an equality of such a kind, as to make it unlawful for the rich to live in any degree of greater elegance than the poor; but an equality is to be observed thus far — that no one is to be allowed to starve, and no one is to hoard his abundance at the expense of defrauding others. The poor man’s homer will be coarse food and a spare diet; the rich man’s homer will be a more abundant portion, it is true, according to his circumstances, but at the same time in such a way that they live temperately, and are not wanting to others.
Commentary on 2 Cor. 8:15
For the system of proportional right in the Church is this — that while they communicate to each other mutually according to the measure of gifts and of necessity, this mutual contribution produces a befitting symmetry [belle harmonie], though some have more, and some less, and gifts are distributed unequally.
Commentary on 2. Cor. 8:14
We have seen already, how that to live well with men, we must obey our superiors. For it is the first thing that God commands us in the second table of his law: because the mean in descending from him to men, is to honor those whom he has set over us. Indeed when we speak of men, there is some equal fellowship: for we come all of Adams race: we be all of one kind: and all this imports an equality among men. Nevertheless forasmuch as it has pleased God to set certain degrees: we must hold us thereunto, and keep that order, so as the party which has any preeminence and dignity, may be acknowledged for such a one as is to be honored. And in this case we must not allege, why is he more esteemed than I? For that comes not of any worthiness that is in one more than in another: but of Gods will, who will have them so honored to whom he has given any preeminence.
