The Epistles of John, assigned to the writer of the Fourth Gospel and the Revelation, testify that God is love and that love is the test of religion. Second John is written to “the elect lady and her children,” probably a church; Third John is addressed to “the beloved Gaius.”

3 John 1

1:12 Demetrius hath good report of all men, and of the truth itself: yea, and we also bear record; and ye know that our record is true.
