1 John 1:1
1:1 we. The author uses the plural “we,” referring undoubtedly to the twelve apostles, but later uses the first person singular when his epistle becomes more personal (e.g., I John 2:1). In any case, it is obvious that the author is the beloved disciple, John, even though he never identifies himself by name. The similarity in vocabulary between John’s gospel and his epistles is strikingly obvious. For example, the word “know” occurs more in the Gospel of John than in any of the other gospels, and occurs in I John more than in any other epistle. Exactly the same phenomenon is noted for many other vocabulary words. These include such words as love, light, truth, fellowship, commandment, abide, witness, eternal, manifest, keep, overcome, beginning, father, son, and others.
