"It is to be noticed that de Loosten and Binet-Sangle lay great stress upon the statements concerning the mental condition of Jesus which have been handed down to us from contemporaries. They appeal to the fact that his opponents among the Pharisees maintain that he is "possessed", and that his family wish to bring him home from Capernaum to Nazareth because he is "beside himself". From this, however, one may only infer that the former wish to discredit him with the people at any cost, and that the relations perceive a change in him and are not able to explain to their satisfaction how it comes about that he sets himself up as a teacher and a prophet. Besides, it should be laid down as certain that the Pharisees and the followers of Jesus do not declare that he is beside himself because he considers himself to be the Messiah, for they know nothing whatever about this claim."
