20 In a great house He now goes farther, and demonstrates by a comparison, that when we see some who, for a time, made a show of distinguished piety and zeal, fall back shamefully, so far from being troubled on account of it, we ought rather to acknowledge that this arrangement is seemly and adapted to the providence of God. Who will find fault with a large house, in which there is abundance of every kind of furniture, and which accordingly contains not only those articles which are fitted for purposes of display, but likewise those which are of a meaner sort? This diversity is even ornamental, if, while the sideboard and the table glitter with gold and silver, the kitchen is furnished with vessels of wood and of earthenware. Why then should we wonder if God, the head of the family, so rich and so abundantly supplied with everything, has in this world, as in a large house, various kinds of men, as so many parts of furniture?
Commentators are not agreed, however, whether the “great house” means the Church alone, or the whole world. And, indeed, the context rather leads us to understand it as denoting the Church; for Paul is not now reasoning about strangers, but about God’s own family. Yet what he says is true generally, and in another passage the same Apostle extends it to the whole world; that is, at Romans 9:21, where he includes all the reprobate under the same word that is here used. We need not greatly dispute, therefore, if any person shall apply it simply to the world. Yet there can be no doubt that Paul’s object is to shew that we ought not to think it strange, that bad men are mixed with the good, which happens chiefly in the Church.
