25 Then, moreover, what a swelling of arrogance it is, what oblivion of humility and gentleness, what a boasting of his own arrogance, that any one should either dare, or think that he is able, to do what the Lord did not even grant to the apostles; that he should think that he can discern the tares from the wheat, or, as if it were granted to him to bear the fan and to purge the threshing-floor, should endeavour to separate the chaff from the wheat; and since the apostle says, “But in a great house there are not only vessels of gold and of silver, but also of wood and of earth,” should think to choose the vessels of gold and of silver, to despise, to cast away, and to condemn the vessels of wood and of clay; while the vessels of wood are not burnt up except in the day of the Lord by the flame of the divine burning, and the vessels of clay are only broken by Him to whom is given the rod of iron.
