For this end God gave us speech, and hands, and feet, and strength of body, and mind, and understanding, that we might use all these things, both for our own salvation, and for our neighbor's advantage. For not for hymns only and thanksgivings is our speech serviceable to us, but it is profitable also for instruction and admonition. And if indeed we used it to this end, we should be imitating our Master; but if for the opposite ends, the devil. Since Peter also, when he confessed the Christ, was blessed, as having spoken the words of the Father; but when he refused the cross, and dissuaded it, he was severely reproved, as savoring the things of the devil. But if where the saying was of ignorance, so heavy is the blame, when we of our own will commit many sins, what favor shall we have?
Such things then let us speak, that of themselves they may be evidently the words of Christ. For not only if I should say, “Arise, and walk;” neither if I should say, “Tabitha, arise,” then only do I speak Christ's words, but much more if being reviled I bless, if being despitefully used I pray for him that does despite to me. Lately indeed I said, that our tongue is a hand laying hold on the feet of God; but now much more do I say, that our tongue is a tongue imitating the tongue of Christ, if it show forth the strictness that becomes us, if we speak those things which He wills. But what are the things which He wills us to speak? Words full of gentleness and meekness, even as also He Himself used to speak, saying to them that were insulting Him, “I have not a devil;” and again, “If I have spoken evil, bear witness of the evil.” If you also speak in this way; if you speak for your neighbor's amendment, you will obtain a tongue like that tongue. And these things God Himself says; “For he that brings out the precious from the vile, shall be as my mouth;” such are His words.
When therefore your tongue is as Christ's tongue, and your mouth has become the mouth of the Father, and you are a temple of the Holy Ghost, then what kind of honor could be equal to this? For not even if your mouth were made of gold, no nor even of precious stones, would it shine like as now, when lit up with the ornament of meekness. For what is more lovely than a mouth that knows not how to insult, but is used to bless and give good words? But if you can not bear to bless him that curses you, hold your peace, and accomplish but this for the time; and proceeding in order, and striving as you ought, you will attain to that other point also, and wilt acquire such a mouth, as we have spoken of.
4. And do not account the saying to be rash. For the Lord is loving to man, and the gift comes of His goodness. It is rash to have a mouth like the devil, to have a tongue resembling that of an evil demon, especially for him that partakes of such mysteries, and communicates of the very flesh of the Lord. Reflecting then on these things, become like Him, to the utmost of your power. No longer then will the devil be able so much as to look you in the face, when you have become such a one as this. For indeed he recognizes the image of the King, he knows the weapons of Christ, whereby he was worsted. And what are these? Gentleness and meekness. For when on the mountain Christ overthrew and laid low the devil who was assaulting him, it was not by making it known that He was Christ, but He entrapped him by these sayings, He took him by gentleness, he turned him to flight by meekness. Thou also must do this; should you see a man become a devil, and coming against you, even so do thou likewise overcome. Christ gave you also power to become like Him, so far as your ability extends. Be not afraid at hearing this. The fear is not to be like Him. Speak then after His manner, and you have become in this respect such as He, so far as it is possible for one who is a man to become so.
Wherefore greater is he that thus speaks, than he that prophecies. For this is entirely a gift, but in the other is also your labor and toil. Teach your soul to frame you a mouth like to Christ's mouth. For it can create such things, if it will; it knows the art, if it be not remiss. And how is such a mouth made? One may ask. By what kind of colorings? By what kind of material? By no colorings, indeed, or material; but by virtue only, and meekness, and humility.
Let us see also how a devil's mouth is made; that we may never frame that. How then is it made? By curses, by insults, by envy, by perjury. For when any one speaks his words, he takes his tongue. What kind of excuse then shall we have; or rather, what manner of punishment shall we not undergo; when this our tongue, wherewith we are allowed to taste of the Lord's flesh, when this, I say, we overlook, speaking the devil's words?
Let us not overlook it, but let us use all diligence, in order to train it to imitate its Lord. For if we train it to this, it will place us with great confidence at Christ's judgment seat. Unless any one know how to speak thus, the judge will not so much as hear him. For like as when the judge chances to be a Roman, he will not hear the defense of one who knows not how to speak thus; so likewise Christ, unless thou speak after His fashion, will not hear you, nor give heed.
Let us learn therefore to speak in such wise as our Judge is wont to hear; let it be our endeavor to imitate that tongue. And should you fall into grief, take heed lest the tyranny of despondency pervert your tongue, but that thou speak like Christ. For He too mourned for Lazarus and Judas. Should thou fall into fear, seek again to speak even as He. For He Himself fell into fear for your sake, with regard to His manhood. the other sheep, that He might indicate the unfruitfulness of the one, for no fruit will come from kids; and the great profit from the other, for indeed from sheep great is the profit, as well from the milk, as from the wool, and from the young, of all which things the kid is destitute.
