John Chrysostom
For by the earth He now means not that which we tread under our feet, but that which was fashioned by His hands, namely, man, upon whom the Lord pours out fire for the consuming of sins, and the renewing of souls.
Now hereby He declared a future event, for it so happened in the same house that there have been believers whose fathers wished to bring them to unbelief; but the power of Christ’s doctrines has so prevailed, that fathers were left by sons, mothers by daughters, and children by parents. For the faithful in Christ were content not only to despise their own, but at the same time also to suffer all things as long as they were not without the worship of their faith. But if He were mere man, how would it have occurred to Him to conceive it possible that He should be more loved by fathers than their children were, by children than their fathers, by husbands than their wives, and they too not in one house or a hundred, but throughout the world? And not only did he predict this, but accomplish it in deed.
