The Epistles of John
1. AUTHORSHIP OF THE FIRST EPISTLE
The First Epistle of John does not contain the name of its author. According to tradition, however, it was written by the apostle John, and tradition is here supported by the characteristics of the epistle itself. The author of the epistle was evidently the same as the author of the Fourth Gospel. The marked similarity in style can be explained in no other way. Even the careless reader observes that the style of the Fourth Gospel is very peculiar. Short sentences are joined to one another with the utmost simplicity; the vocabulary is limited, but contains expressions of extraordinary richness; the total effect is singularly powerful. These same characteristics, though they are so peculiar, appear also in the epistle. There is the same simplicity of sentence structure, the same use of such terms as "life" and "light" and "love," the same indescribable spirit and tone. Yet the epistle is no slavish imitation of the Gospel—differences stand side by side with the similarities. These two works are evidently related, not as model and copy, but as living productions of the same remarkable personality.
2. TESTIMONY OF AN EYEWITNESS
As in the Gospel, so also in the epistle the author presents himself clearly as an eyewitness of the life of Jesus, I John 1:1-3; 4:14; as in the Gospel he lays stress upon simple testimony. Even those things which have just been noticed as characteristic of his style are connected ultimately with the teaching of Jesus. In both Gospel and epistle, the beloved disciple has reproduced what he heard in Galilee and in Judea, though in both he has made the memory a living, spiritual fact.
3. DESTINATION AND DATE
The First Epistle of John is perhaps scarcely to be called an epistle at all. Practically all the characteristics of a letter are missing. There is no address; there is no greeting at the close; there are no personal details. The readers are indeed referred to in the second person; but preachers as well as letter-writers say, "you." First John is a sort of general address written probably to some extended group of churches.
These churches are probably to be sought in Asia Minor. Throughout the epistle the readers are addressed in a fatherly tone. See, for example, ch. 2:1. Evidently the writer was well known as a sort of patriarch throughout an extended region. Such conditions prevailed in Asia Minor after the apostle John had begun to reside at Ephesus. Trustworthy tradition as well as the New Testament informs us of a period in the apostle's life when he had outlived all or most of the other apostles and was revered as the head of the Asian church. At some time within this period—probably nearer the end than the beginning—the First Epistle of John was written.
4. THE FALSE TEACHERS
The form of error against which the epistle is directed becomes clearest, perhaps in ch. 4:2,3. The false teachers had denied that Jesus Christ was come in the flesh. This may be interpreted in several different ways.
