John Chrysostom — as excerpted in the Catena Aurea on Matthew 16:24-25

“(Hom. lv.) Peter had said, Be it far from thee, Lord, this shall not be unto thee; and had been answered, Get thee behind me, Satan; but the Lord was not satisfied with this rebuke, but over and above desired to shew the impropriety of those things which Peter had said, and the fruit of His own passion; whence it is added, Then said Jesus to his disciples, If any man will to come after me, let him deny himself, and take up his cross, and follow me; as much as to say, You say unto me, Be it far from thee; but I say unto you, that not only is it harmful for you to hinder Me from My Passion, but yourself will not be able to be saved unless you suffer and die, and renounce your life always. And note, that He does not speak of it as compulsory, for He does not say, Though ye will not yet must ye suffer this, but, If any man will. By saying this He rather attracted them; for he who leaves his auditor at liberty, attracts him the more; whereas he that uses violence oftentimes hinders him. And He proposes this doctrine, not to His disciples only, but in common to the whole world, saying, If any man will, that is, if woman, if man, if king, if free, if slave; there are three things mentioned; let him deny himself, take up his cross, and follow me.”
