John 7:15

15.And the Jews wondered Those who think that Christ was received in such a manner as to be esteemed and honored are mistaken; for the wonder or astonishment of the Jews is of such a nature, that they seek occasion from it to despise him. For such is the ingratitude of men that, in judging of the works of God, they always seek deliberately an occasion of falling into error. If God acts by the usual means and in the ordinary way, those means which are visible to the eyes are — as it were — veils which hinder us from perceiving the Divine hand; and therefore we discern nothing in them but what is human. But if an unwonted power of God shines above the order of nature and the means generally known, we are stunned; and what ought to have deeply affected all our senses passes away as a dream. For such is our pride, that we take no interest in any thing of which we do not know the reason.

How doth this man know letters? It was an astonishing proof of the power and grace of God, that Christ, who had not been taught by any master, was yet eminently distinguished by his knowledge of the Scriptures; and that he, who had never been a scholar, should be a most excellent teacher and instructor. But for this very reason the Jews despise the grace of God, because it exceeds their capacity. Admonished by their example, therefore, let us learn to exercise deeper reverence for God than we are wont to do in the consideration of his works.
