His parables are sometimes interpreted as allegories in the gospels themselves and in Christian tradition. In such an allegory, each element corresponds metaphorically to a class of people (e.g., false Christians), a heavenly reward, or some other topic. The gospel of John includes allegories but no parables.
Believed to be the words of Jesus, taught to him by the Father, Christians place high significance on the parables.
28So Jesus said to them, "When you have lifted up the Son of Man, then you will know that I am he, and that I do nothing on my own authority, but speak just as the Father taught me. —John 8:28occurrence
Parables are attributed to Jesus in the three synoptic gospels of the New Testament and the noncanonical Gospel of Thomas. According to some interpretations, the Gospel of John also contains a parable.
According to one source the Gospel of Luke contains both the largest total number of parables (24) and the largest number of unique parables found nowhere else (10). The Gospel of Matthew contains 23 parables of which six are unique. The noncanonical Gospel of Thomas contains 15 parables of which two are unique. The Gospel of Mark contains eight parables of which only one (the Parable of the Growing Seed) is unique. The Gospel of John contains only the story of the Vine, which some consider to be a parable.
