Eusebius of Caesarea
Catena Aurea · Lukasevangelium 16
And the Pharisees also, who were covetous, heard all these things: and they derided him. And he said unto them, Ye are they which justify yourselves before men; but God knoweth your hearts: for that which is highly esteemed among men is abomination in the sight of God. The Law and the Prophets were until John: since that time the kingdom of God is preached, and every man presseth into it. And it is easier for heaven and earth to pass, than one tittle of the law to fail. Whosoever putteth away his wife, and marrieth another, committeth adultery: and whosoever marrieth her that is put away from her husband committeth adultery.
A great struggle befals men in their ascent to heaven. For that men clothed with mortal flesh should be able to subdue pleasure and every unlawful appetite, desiring to imitate the life of angels, must be compassed with violence. But who that looking upon those who labour earnestly in the service of God, and almost put to death their flesh, will not in reality confess that they do violence to the kingdom of heaven.
