The letter known as 2 John is addressed to “the elect lady and her children” which is most likely a reference to the church body to whom he was writing. In it, John encourages the church to continue in love and to reject false teaching. You’ll hear echoes of 1 John as tells the church that those remain in Christ’s teaching have both the Father and the Son. In 3 John, the apostle commends his friend Gaius, who is likely a pastor, and writes to warn him about Diotrophes who loves attention, power, divisive speech, and who probably already had a twitter account. John encourages Gaius to refrain from imitating what is evil and imitate what is good.
