Chapter Ten
Answer to an objection based on S. Matt, xvii. 15: "Have pity on my son, for he is lunatic," although it was not the effect of the moon, but of a demon.
[In answering this question, we will also consider the apparently uncalled-for rebuke which Christ adds to the multitude, in the words "O faithless generation, how long shall I be with you ? "
The dragon or demon was cunning enough to attack the boy at the changes of the moon, so that men might think that his sufferings were due to its influence. Thus by one act he accomplished two objects, for he both tortured the boy's body, and suggested blasphemy to the minds of those who saw it, for if they ascribed it to the moon's action, they would naturally blame Him who created the moon.
Christ perceives that they likewise have been affected by the demon, and so calls them a "faithless generation," because of their ideas about the moon. By expelling the demon, He shows them their error.
S. Matthew does not prove, by saying that "a lunatic boy" was brought to Christ, that he really was under the moon's influence. Like a good historian, he recorded things as he heard them, not as they actually were.]
