For John had said unto Herod, It is not lawful for you to have your brother's wife.
All Commentaries on Mark 6:18 Go To Mark 6
John Chrysostom
AD 407
John saw a man that was a tyrant overthrowing the divine commands on marriage. With boldness, he proclaimed in the midst of the forum, “It is not lawful for you to have your brother Philip’s wife.” So we learn from him to admonish our fellow servant as an equal. Do not shrink from the duty of chastising a brother, even though one may be required to die for it. Now do not make this cold reply: “What does it matter to me? I have nothing in common with him.” With the devil alone we have nothing in common, but with all humanity we have many things in common. All partake of the same nature with us. They inhabit the same earth. They are nourished with the same food. They have the same Lord. They have received the same laws. They are invited to the same blessings with ourselves. Let us not say then that we have nothing in common with them.
