Mark 9:17Meaning & Commentary from the Church Fathers

He likewise reproaches the disciples of Jesus, treating them as if they were all lacking in faith. However, his intention was not to bring charges against them publicly, but rather to address them privately.

Why did he exhibit such symptoms of distress, displaying foaming at the mouth and grinding his teeth? This occurs because in individuals possessed by demons, the brain is primarily targeted, serving as the command center through which the demon exerts control over the entire body, akin to a stronghold. When the brain is troubled, it leads to an inflammatory response affecting the nerves and joints, disrupting the regular functioning that emanates from this mental center. Consequently, this results in chaos and disarray, manifesting in involuntary movements throughout the body, particularly affecting the jaws, which are closest to the brain.

The Father is not presently seeking assistance from Jesus; it is clear that at this moment, He does not anticipate receiving help from Him either.

In this moment, Jesus arrives, and the crowd rushes to welcome Him. However, the father of the boy afflicted by demons initially implores Him from a distance to take notice of his distressed son. Approaching closer and kneeling before Him, he elaborates on the boy's torments, pleads for compassion, and mentions that Jesus' disciples were unable to heal him.

During that time, the father of the afflicted child compelled his way through the throng. He knelt before the Lord and, in a loud voice, laid bare his tragedy, revealing that his son endured severe episodes of possession, was utterly deaf and mute, and experienced intense suicidal impulses, having already cast himself into both fire and water. He presented the boy to the disciples, yet they were unable to drive out the unclean spirit, which only provided an opportunity for the scribes to mock them.
