This short epistle, 2nd John, is addressed from an elder to a "chosen lady and her children," expressing love and joy for those walking in truth. It emphasizes the importance of mutual love among believers, defined as obedience to God's commands. The text warns against "deceivers" who deny Jesus Christ's coming in the flesh, identifying them as the antichrist, and advises against welcoming those who do not adhere to Christ's teaching. The author expresses a desire for a face-to-face meeting rather than further writing, concluding with greetings from a "chosen sister's children."
