Exposition of the Old and New Testament, by John Gill, [1746-63], at sacred-texts.com
The Colossians, to whom this epistle is written, were not the Rhodians, by some called Colossians, from Colossus, the large statue of the sun, which stood in the island of Rhodes, and was one of the seven wonders of the world; but the inhabitants of Colosse, a city of the greater Phrygia, in the lesser Asia, near to which stood the cities of Laodicea and Hierapolis, mentioned in this epistle. Pliny (a) speaks of it as one of the chief towns in Phrygia, and (b) Herodotus calls it the great city of Phrygia; it is said to have perished a very little time after the writing of this epistle, with the above cities, by an earthquake, in the year of Christ 66, and in the tenth of Nero (c); though it was afterwards rebuilt; for Theophylact says, that in his time it was called Chonae. When the Gospel was brought hither, and by whom, is not known, nor who was the founder of the church in this place; for the Apostle Paul was not, since his face had never been seen by them, Col 2:1, though it is said that Epaphras, the same name with Epaphroditus, was fixed by him pastor of this church; and others say Philemon was set over it by him. The occasion of this epistle was this, Epaphras, who had preached the Gospel to the Colossians, and very likely was the first that did, came to Rome, where the Apostle Paul was a prisoner, and gave him an account of them, how they had heard and received the Gospel, and of their faith Christ, and love to the saints; and also declared to him in what danger they were through some false teachers that had got among them, who were for introducing the philosophy of the Gentiles, the ceremonies of the law of Moses, and some pernicious tenets of the followers of Simon Magus, and the Gnostics; upon which the apostle writes this epistle to them, to confirm them in the faith of the Gospel Epaphras had preached unto them, and which was the same he himself preached; and to warn them against those bad men, and their principles; and to exhort them to a discharge of their duty to God, and men, and one another. It was written by the apostle, when in bonds at Rome, as many passages in it show, and about the same time with those to the Philippians and Ephesians; and the epistle to the latter greatly agrees with this, both as to subject and style. Dr. Lightfoot places it in the year of Christ 60, in the second of the apostle's imprisonment, and in the sixth of Nero's reign.
