2 John 1
There were some serious doubts about who authorized these 2nd and 3rd epistles. Each were written to a single individual and not for general circulation at that time, thus they were not frequently referred to in the early church by others. Because of their brevity the external and internal proofs are less full and clear than in other books. Then we have the fact that the writer did not affix his name to these letters. However, they really sound Johnish. The fact that the writer did not identify himself is very typical of John to by-pass self-identification. Of the time and place these epistles were written nothing is known.
2 John purports to be addressed to "the elect lady." There has been great diversity of opinion in regards to the person here referred to, and there are questions respecting it, which makes it impossible to determine with absolute certainty. It seems the letter was addressed to an individual, and not a church. If it had been to a particular church it would have been specified, for this is the uniform mode in the New Testament.
Though brief, and though addressed to individuals, 2nd and 3rd John are admitted to the canon of Scripture with the same propriety as the espistles of Timothy, Titus, and Philemon, for those were addressed also to individuals. Like those epistles, these contain things of general interest to the church.
