who wrote the book of 1 2 3 john
First Epistle of John The First Epistle of John, often referred to as First John and written 1 John, is the first of the Johannine epistles of the New Testament, and the fourth of the catholic epistles. 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.[1] 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.[1]
Gospel of John John is usually dated to AD 90â€“110.[17][Notes 6] It arose in a Jewish Christian community in the process of breaking from the Jewish synagogue.[18] Scholars believe that the text went through two to three redactions, or "editions", before reaching its current form.[19][20]
