O GOD, the strength of all those who put their trust in thee; Mercifully accept our prayers; and because, through the weakness of our mortal nature, we can do no good thing without thee, grant us the help of thy grace, that in keeping thy commandments we may please thee, both in will and deed; through Jesus Christ our Lord. Amen.

"Now," saith he, "are ye of God little children, and have overcome him:" whom but Antichrist? For above he had said, "Whosoever unmaketh Jesus Christ and denieth that He is come in the flesh is not of God." Now we expounded, if ye remember, that all those who violate charity deny Jesus Christ to have come in the flesh. For Jesus had no need to come but because of charity: as indeed the charity we are commending is that which the Lord Himself commendeth in the Gospel, "Greater love than this can no man have, that a man lay down his life for his friends." How was it possible for the Son of God to lay down His life for us without putting on flesh in which He might die? Whosoever therefore violates charity, let him say what he will with his tongue, his life denies that Christ is come in the flesh; and this is an antichrist, wherever he may be, whithersoever he have come in. But what saith the apostle to them who are citizens of that country for which we sigh? "Ye have overcome him." And whereby have they overcome? "Because greater is He that is in you, than he that is in this world." Lest they should attribute the victory to their own strength, and by arrogance of pride should be overcome, (for whomsoever the devil makes proud, he overcomes,) wishing them to keep humility, what saith he? "Ye have overcome him." Every man now, at hearing this saying, "Ye have overcome," lifts up the head, lifts up the neck, wishes himself to be praised. Do not extol thyself; see who it is that in thee hath overcome. Why hast thou overcome? "Because greater is He that is in you, than he that is in the world." Be humble, bear thy Lord; be thou the beast for Him to sit on. Good is it for thee that He should rule, and He guide. For if thou have not Him to sit on thee, thou mayest lift up the neck, mayest strike out the heels: but woe to thee without a ruler, for this liberty sendeth thee among the wild beasts to be devoured!
