John 15 is the fifteenth chapter in the Gospel of John in the New Testament section of the Christian Bible. It is part of what New Testament scholars have called the 'farewell discourses' of Jesus. It has historically been a source of Christian teaching, Christological debate and reflection, and its images (particularly of Jesus as the vine) have been influential in Christian art and iconography. The chapter implies one of the highest and most developed Christologies to be found in the New Testament.
