III John 1:10

if I come-- (Jo3 1:14). I will remember--literally, "I will bring to mind" before all by stigmatizing and punishing. prating--with mere silly tattle. neither doth he . . . receive the brethren--with hospitality. "The brethren" are the missionaries on their journey. forbiddeth them that would--receive them. casteth them--those that would receive the brethren, by excommunication from the Church, which his influence, as a leading man (Jo3 1:9) in it, enabled him to do. NEANDER thinks that the missionaries were JEWS by birth, whence it is said in their praise they took nothing from THE GENTILES: in contrast to other Jewish missionaries who abused ministers' right of maintenance elsewhere, as Paul tells us, Co2 11:22; Phi 3:2, Phi 3:5, Phi 3:19. Now in the Gentile churches there existed an ultra-Pauline party of anti-Jewish tendency, the forerunners of Marcion: Diotrephes possibly stood at the head of this party, which fact, as well as this domineering spirit, may account for his hostility to the missionaries, and to the apostle John, who had, by the power of love, tried to harmonize the various elements in the Asiatic churches. At a later period, Marcion, we know, attached himself to Paul alone, and paid no deference to the authority of John.

In this epistle the apostle congratulates Gaius upon the prosperity of his soul (Jo3 1:1, Jo3 1:2), upon the fame he had among good Christians (Jo3 1:3, Jo3 1:4), and upon his charity and hospitality to the servants of Christ (Jo3 1:5, Jo3 1:6). He complains of contemptuous treatment by an ambitious Diotrephes (Jo3 1:9, Jo3 1:10), recommends Demetrius (Jo3 1:12), and expresses his hope of visiting Gaius shortly (Jo3 1:13, Jo3 1:14).
