Was Jesus Mentally Ill?

I am presently in the process of writing a book, which I am calling “The Gospel According to Jesus.” It is the gospel story told from the perspective of Jesus, as a teacher of nonduality. In involves me very slowly studying the Gospel of Mark, both in English translation and the Greek text. Then comparing the passages to parallel accounts in the other gospels and the Gospel of Thomas. This process enables me to see things that I might not ordinarily see, and ponder things that I would not normally ponder.

Recently one passage caught my attention. It is the story that takes place early in Jesus’ ministry where Jesus’ family comes Capernaum to find Jesus and take him home because they thought he had “lost his senses,” as one translation puts it. Today we would say he was mentally ill. A parallel passage in John’s gospel says that “he has a demon and is insane.” 

People were saying that Jesus was demon-possessed, which was the explanation in the first century for all sorts of mental and physical illnesses, from schizophrenia to epilepsy. According to the story scribes from Jerusalem were saying, “He is possessed by Beelzebul,” and “He casts out the demons by the ruler of the demons.”

It got me thinking, “Was Jesus mentally ill?”
