1 John 4:17

He tells how each may prove himself, what progress charity has made in him or rather what progress he has made in charity. For if charity is God, God is capable neither of proficiency nor of deficiency: that charity is said to be making proficiency in thee, means only that thou makest proficiency in it. Ask therefore what proficiency thou hast made in charity, and what thine heart will answer thee, that thou mayest know the measure of thy profiting. For he has promised to show us in what we may know Him, and hath said, "In this is love made perfect in us." Ask, in what? "That we have boldness in the day of judgment." Whoso hath boldness in the day of judgment, in that man is charity made perfect. What is it to have boldness in the day of judgment? Not to fear lest the day of judgment should come.

Now in proportion as this man who has begun to fear the day of judgment, mortifies his members which are upon the earth, in that proportion the heavenly members rise up and are strengthened. But the heavenly members are all good works. As the heavenly members rise up, he begins to desire that which once he feared. Once he feared lest Christ should come and find in him the impious whom He must condemn; now he longs for Him to come, because He shall find the pious man whom He may crown. Having now begun to desire Christ's coming, the chaste soul which desires the embrace of the Bridegroom renounces the adulterer, becomes a virgin within by faith, hope, and charity. Now hath the man boldness in the day of judgment: he fights not against himself when he prays, "Thy kingdom come."

Thou hast heard the ground of thy boldness: "Because as He is," saith the apostle, "are we also in this world." Does he not seem to have said something impossible? For is it possible for man to be as God? I have already expounded to you that "as" is not always said of equality, but is said of a certain resemblance. For how sayest thou, As I have ears, so has my image? Is it quite so? and yet thou sayest "so, as." If then we were made after God's image, why are we not so as God? Not unto equality, but relatively to our measure. Whence then are we given boldness in the day of judgment? "Because as He is, are we also in this world." We must refer this to the same charity, and understand what is meant.

The Lord in the Gospel saith, "If ye love them that love you, what reward shall ye have? do not the publicans this?" Then what would He have us do? "But I say unto you, Love your enemies, and pray for them that persecute you." If then He bids us love our enemies, whence brings He an example to set before us? From God Himself: for He saith, "That ye may be the children of your Father which is in heaven." How doth God this? He loveth His enemies, "Who maketh His sun to rise upon the good and the bad, and raineth upon the just and the unjust." If this then be the perfection unto which God inviteth us, that we love our enemies as He loved His; this is our boldness in the day of judgment, that "as He is, so are we also in this world:" because, as He loveth His enemies in making His sun to rise upon good and bad, and in sending rain upon the just and unjust, so we, since we cannot bestow upon them sun and rain, bestow upon them our tears when we pray for them.

Some man has begun to believe in a day of judgment: if he has begun to believe, he has also begun to fear. But because he fears as yet, because he hath not yet boldness in the day of judgment, not yet is charity in that man made perfect. But for all that, is one to despair? In whom thou seest the beginning, why despairest thou of the end? What beginning do I see? That very fear. Hear the Scripture: "The fear of the Lord is the beginning of wisdom." Well then, he has begun to fear the day of judgment: by fearing let him correct himself, let him watch against his enemies, i.e. his sins; let him begin to come to life again inwardly, and to mortify his members which are upon the earth.
