THE SECOND EPISTLE OF JOHN
Introduction
We treat these small documents [2nd and 3rd Epistles of John] together. No intelligent person can doubt that both Epistles were written by the same person. We do not need to investigate the objections and inventions of rationalists like Bretschneider, those of the so-called Tuebingen school and the modern critics, who deny the Johannine authorship and teach that the fictitious “John the Presbyter of Ephesus “ wrote these two letters.
But all these modern conceptions are answered by the ancient authorities which ascribe both Epistles to the writer of the First Epistle, that is, the Apostle John. Irenaeus, who as a boy had listened to Polycarp, who knew John personally, bears witness to the genuineness of the Second Epistle, so does Clement of Alexandria, the Muratorian fragment, Dionysius of Alexandria, and others. Both Epistles seem to have been accepted from the very beginning as the inspired testimony of John.
The internal evidence is conclusive. Both Epistles are in tone, style and vocabulary like the Gospel of John and the First Epistle of John. The great characteristic words of the other writings of John (the Gospel and John 1:1) “Love,” “truth,” “world,” etc., are found in these two Epistles. They are, indeed, complementary to the First Epistle and give some of the truths contained in the First Epistle in a practical way. The warning contained in the Second Epistle concerning receiving one who does not bring the doctrine of Christ, that is, an antichrist, connects closely with the instructions of 1 John 4:1. There is no question but both Epistles are appendices to the First Epistle.
