19:21-31 Persons who came from afar to pay their devotions at the temple of Ephesus, bought little silver shrines, or models of the temple, to carry home with them. See how craftsmen make advantage to themselves of people's superstition, and serve their worldly ends by it. Men are jealous for that by which they get their wealth; and many set themselves against the gospel of Christ, because it calls men from all unlawful crafts, however much wealth is to be gotten by them. There are persons who will stickle for what is most grossly absurd, unreasonable, and false; as this, that those are gods which are made with hands, if it has but worldly interest on its side. The whole city was full of confusion, the common and natural effect of zeal for false religion. Zeal for the honour of Christ, and love to the brethren, encourage zealous believers to venture into danger. Friends will often be raised up among those who are strangers to true religion, but have observed the honest and consistent behaviour of Christians.

27. So that not only this our craft is in danger … but, &c.—that is, "that indeed is a small matter; but there is something far worse." So the masters of the poor Pythoness put forward the religious revolution which Paul was attempting to effect at Philippi, as the sole cause of their zealous alarm, to cloak the self-interest which they felt to be touched by his success (Ac 16:19-21). In both cases religious zeal was the hypocritical pretext; self-interest, the real moving cause of the opposition made.

also the temple of the great goddess Diana … despised, and her magnificence … destroyed, whom all Asia and the world worshippeth—It was reckoned one of the wonders of the world. It was built about 550 B.C., of pure white marble, and though burned by a fanatic on the night of the birth of Alexander the Great, 356 B.C., was rebuilt with more splendor than before. It was four hundred twenty-five feet long by two hundred twenty broad, and the columns, one hundred twenty-seven in number, were sixty feet in height, each of them the gift of a king, and thirty-six of them enriched with ornament and color. It was constantly receiving new decorations and additional buildings, statues, and pictures by the most celebrated artists, and kindled unparalleled admiration, enthusiasm, and superstition. Its very site is now a matter of uncertainty. The little wooden image of Diana was as primitive and rude as its shrine was sumptuous; not like the Greek Diana, in the form of an imposing huntress, but quite Asiatic, in the form of a many-breasted female (emblematic of the manifold ministrations of Nature to man), terminating in a shapeless block. Like some other far-famed idols, it was believed to have fallen from heaven (Ac 19:35), and models of it were not only sold in immense numbers to private persons, but set up for worship in other cities [Howson]. What power must have attended the preaching of that one man by whom the death blow was felt to be given to their gigantic and witching superstition!
