The gospel went through two or three "editions" before reaching its current form around AD 90–110. It speaks of an unnamed "disciple whom Jesus loved" as the source of its traditions, but does not say specifically that he is its author; Christian tradition identifies this disciple as the apostle John, but while this idea still has supporters, for a variety of reasons the majority of modern scholars have abandoned it or hold it only tenuously. It is significantly different from the synoptic gospels, with major variations in material, theological emphasis, chronology, and literary style, sometimes amounting to contradictions.
