2 Corinthians 8:14 - Ellicott's Commentary On The Whole Bible

But by an equality. — The meaning of the word is obvious. The Church of Jerusalem was at this time suffering from poverty, and, therefore, St. Paul exhorts the Corinthians to come to its assistance. A time might come in which their relative position would be inverted, and then he would plead not less earnestly that Jerusalem should assist Corinth. It is reading too much between the lines to see in the words the thought which the Apostle expresses elsewhere (Romans 15:27), that the equality of which he speaks consisted in the Corinthians giving money and receiving spiritual privileges. But for the fact that controversial ingenuity is “capable of anything,” it might have been thought impossible to see in them the doctrine that men are to give to the poor in order that, in their time of need, in the hour of death, and in the day of judgment, they might receive from them a transfer of their superfluous merits. And yet this has actually been done by Roman Catholic commentators — even by such as Estius.
