St. John praises Gaius for his walking in truth and for his charity, complains of the bad conduct of Diotrephes and gives a good testimony to Demetrius.

3 John Chapter 1

1:1   The Ancient, to the dearly beloved Gaius, whom I love in truth.
1:2   Dearly beloved, concerning all things I make it my prayer that thou mayest proceed prosperously and fare well, as thy soul doth prosperously.
1:3   I was exceedingly glad when the brethren came and gave testimony to the truth in thee, even as thou walkest in the truth.
1:4   I have no greater grace than this, to hear that my children walk in truth.

No greater grace. . .that is nothing that gives me greater joy and satisfaction.

1:5   Dearly beloved, thou dost faithfully whatever thou dost for the brethren:  and that for strangers,
1:6   Who have given testimony to thy charity in the sight of the church.  Whom thou shalt do well to bring forward on their way in a manner worthy of God:
1:7   Because, for his name they went out, taking nothing of the Gentiles.

Taking nothing of the Gentiles. . .These ministers of the gospel are commended by St. John, who took nothing from the Gentiles, lest they should seem to preach in order to get money by t.

1:8   We therefore ought to receive such:  that we may be fellow helpers of the truth.
1:9   I had written perhaps to the church:  but Diotrephes, who loveth to have the preeminence among them, doth not receive us.

Diotrephes who loveth. . .This man seemeth to be in power, but not a friend to the faithful; therefore this part of the letter might be an admonition to him from the apostle.

1:11  Dearly beloved, follow not that which is evil:  but that which is good.  He that doth good is of God:  he that doth evil hath not seen God.
1:12  To Demetrius, testimony is given by all, and by the truth itself: yea and we also give testimony.  And thou knowest that our testimony is true.
1:13  I had many things to write unto thee:  but I would not by ink and pen write to thee.
1:14  But I hope speedily to see thee:  and we will speak mouth to mouth.  Peace be to thee.  Our friends salute thee.  Salute the friends by name.
