It is attributed to John the Evangelist, traditionally thought to be the author of the Gospel of John and the other two Johannine epistles . This epistle was probably written in Ephesus in AD 95--110 . The work was written to counter docetism, which is the belief that Jesus did not come "in the flesh", but only as a spirit . It also defined how Christians are to discern true teachers: by their ethics, their proclamation of Jesus in the flesh, and by their love . </P> <P> The main themes of the epistle are love and fellowship with God . The author describes various tests by which readers may ascertain whether or not their communion with God is genuine, and teaches that the proof of spiritual regeneration is a life of active righteousness . It also distinguishes between the world (which is full of evil and under the dominion of Satan) and the children of God (who are set apart from the world). </P>
