I wrote unto the church: but Diotrephes, who loveth to have the preeminence among them, receiveth us not. I wrote unto the Church - The Church where Caius was; but Diotrephes, who loveth to have the pre-eminence, φιλοπρωτευων, who loves the presidency, or chief place in the Church. He was doubtless an officer in the Church, at least a deacon, probably a bishop; and, being one, he magnified himself in his office; he loved such eminence, and behaved himself haughtily in it.
Receiveth us not - Does not acknowledge the apostolical authority. As some MSS. supply αν after εγραψα, and several judicious critics believe it is implied, the translation will run thus: I would have written to the Church to receive these men kindly, but Diotrephes, who affects the presidency; and into whose hands, if I wrote to the Church, my letter must come, receiveth us not - would not acknowledge my authority to interfere with any of the matters of his Church; and therefore I have written unto thee, whose love to the brethren and general hospitality are well known, that thou wouldst receive those strangers and persecuted followers of our common Lord.
