His disciples had abandoned him. Fr. Martin is correct. Indeed, he did not tell the disciple he loved to baptize the world but to take care of Mary. In doing so he abandoned his divine nature (which Mary told him of in the story of his birth) and his Church. This solves the mystery of why he cried out to his Father in anguish and why we are saved (and what kind of morality this implies). Jesus was not making up for the disobedience of a mythical Adam but for the sadness of the human heart, which he first had to experience in the most extreme form.
