11. "Beloved, believe not every spirit." [2330] Because he had said, "In this we know that He abideth in us, by the Spirit which He hath given us." But how this same Spirit is known, mark this: "Beloved, believe not every spirit, but prove the spirits whether they be from God." And who is he that proves the spirits? A hard matter has he put to us, my brethren! It is well for us that he should tell us himself how we are to discern them. He is about to tell us: fear not: but first see; mark: see that hereby is expressed the very thing that vain heretics [2331] taunt us withal. Mark, see what he says, "Beloved, believe not every spirit, but prove the spirits whether they be from God." The Holy Spirit is spoken of in the Gospel by the name of water; where the Lord "cried and said, If any man thirst, let him come unto me, and drink. He that believeth on me, out of his belly shall flow rivers of living water." [2332] But the evangelist has expounded of what He said this: for he goes on to say, "But this spake He of the Spirit, which they that believed on Him should receive." Wherefore did not the Lord baptize many? But what saith he? "For the Holy Ghost was not yet given; because that Jesus was not yet glorified." Then seeing those had baptism, and had not yet received the Holy Ghost, whom on the day of Pentecost the Lord sent from heaven, the glorifying of the Lord was first waited for, so that the Spirit might be given. Even before He was glorified, and before He sent the Spirit, He yet invited men to prepare themselves for the receiving of the water of which He said, "Whoso thirsteth, let him come and drink;" and, "He that believeth on me, out of his belly shall flow rivers of living water." What meaneth, "Rivers of living water"? What is that water? Let no man ask me; ask the Gospel. "But this," saith it, "He said of the Spirit, which they should receive that should believe on Him." Consequently, the water of the sacrament is one thing: another, the water which betokens the Spirit of God. The water of the sacrament is visible: the water of the Spirit invisible. That washes the body, and betokens that which is done in the soul. By this Spirit the soul itself is cleansed and fed. This is the Spirit of God, which heretics and all that cut themselves off from the Church, cannot have. And whosoever do not openly cut themselves off, but by iniquity are cut off, and being within, whirl about as chaff and are not grain; these have not this Spirit. This Spirit is denoted by the Lord under the name of water: and we have heard from this epistle, "Believe not every spirit;" and those words of Solomon bear witness, "From strange water keep thee far." [2333] What meaneth, "water"? Spirit. Does water always signify spirit? Not always: but in some places it signifies the Spirit, in some places it signifies baptism, in some places signifies peoples, [2334] in some places signifies counsel: thus thou findest it said in a certain place, "Counsel is a fountain of life to them that possess it." [2335] So then, in divers places of the Scriptures, the term "water" signifies divers things. Now however by the term water ye have heard the Holy Spirit spoken of, not by an interpretation of ours but by witness of the Gospel, where it saith, "But this said He of the Spirit, which they should receive that should believe on Him." If then by the name of water is signified the Holy Spirit, and this epistle saith to us, "Believe not every spirit, but prove the spirits, whether they be of God;" let us understand that of this it is said, "From strange water keep thee far, and from a strange fountain drink thou not." [2336] What meaneth, "From a strange fountain drink thou not"? A strange spirit believe thou not.
12. There remains then the test by which it is to be proved to be the Spirit of God. He has indeed set down a sign, and this, belike, difficult: let us see, however. We are to recur to that charity; it is that which teacheth us, because it is the unction. However, what saith he here? "Prove the spirits, whether they be from God: because many false prophets have gone out into this world." Now there are all heretics and all schismatics. How then am I to prove the spirit? He goes on: "In this is known [2337] the Spirit of God." Wake up the ears of your heart. We were at a loss; we were saying, Who knows? who discerns? Behold, he is about to tell the sign. "Hereby is known the Spirit of God: every spirit that confesseth that Jesus Christ is come in the flesh is of God: and every spirit that confesseth not that Jesus Christ is come in the flesh is not of God: and this is the antichrist, of whom ye have heard that he should come; and even now already is he in this world." [2338] Our ears, so to say, are on the alert for discerning of the spirits; and we have been told something, such that thereby we discern not a whit the more. For what saith he? "Every spirit that confesseth that Jesus Christ came in the flesh, is of God." Then is the spirit that is among the heretics, of God, seeing they "confess that Jesus Christ came in the flesh"? Aye, here perchance they lift themselves up against us, and say: Ye have not the Spirit from God; but we confess "that Jesus Christ came in the flesh:" but the apostle here hath said that those have not the Spirit of God, who confess not "that Jesus Christ came in the flesh." Ask the Arians: they confess "that Jesus Christ came in the flesh:" ask the Eunomians; they confess "that Jesus Christ came in the flesh:" ask the Macedonians; they confess "that Jesus Christ came in the flesh:" put the question to the Cataphryges; they confess "that Jesus Christ came in the flesh:" put it to the Novatians; they confess "that Jesus Christ came in the flesh." Then have all these heresies the Spirit of God? Are they then no false prophets? Is there then no deception there, no seduction there? Assuredly they are antichrists; for "they went out from us, but were not of us."
13. What are we to do then? By what to discern them? Be very attentive; let us go together in heart, and knock. Charity herself keeps watch; for it is none other than she that shall knock, she also that shall open: anon ye shall understand in the name of our Lord Jesus Christ. Already ye have heard that it was said above, "Whoso denieth that Jesus Christ is come in the flesh, the same is an antichrist." There also we asked, Who denies? because neither do we deny, nor do those deny. And we found that some do in their deeds deny; [2339] and we brought testimony from the apostle, who saith, "For they confess that they know God, but in their deeds deny Him." [2340] Thus then let us now also make the enquiry in the deeds not in the tongue. What is the spirit that is not from God? That "which denieth that Jesus Christ is come in the flesh." And what is the spirit that is from God? That "which confesseth that Jesus Christ is come in the flesh." Who is he that confesseth that Jesus Christ is come in the flesh? Now, brethren, to the mark! let us look to the works, not stop at the noise of the tongue. Let us ask why Christ came in the flesh, so we get at the persons who deny that He is come in the flesh. If thou stop at tongues, why, thou shalt hear many a heresy confessing that Christ is come in the flesh: but the truth convicteth those men. Wherefore came Christ in the flesh? Was He not God? Is it not written of Him, "In the beginning was the Word, and the Word was with God, and the Word was God?" [2341] Was it not He that did feed angels, is it not He that doth feed angels? Did He not in such sort come hither, that He departed not thence? Did He not in such sort ascend, that He forsook not us? Wherefore then came He in the flesh? Because it behooved us to have the hope of resurrection shown unto us. God He was, and in flesh He came; for God could not die, flesh could die; He came then in the flesh, that He might die for us. But how died He for us? "Greater charity than this hath no man, that a man lay down his life for his friends." [2342] Charity therefore brought Him to the flesh. Whoever therefore has not charity denies that Christ is come in the flesh. Here then do thou now question all heretics. Did Christ come in the flesh? "He did come; this I believe, this I confess." Nay, this thou deniest. "How do I deny? Thou hearest that I say it!" Nay, I convict thee of denying it. Thou sayest with the voice, deniest with the heart; sayest in words, deniest in deeds. "How," sayest thou, "do I deny in deeds?" Because the end for which Christ came in the flesh, was, that He might die for us. He died for us, because therein He taught much charity. "Greater charity than this hath no man, that a man lay down his life for his friends." Thou hast not charity, seeing thou for thine own honor dividest unity. Therefore by this understand ye the spirit that is from God. Give the earthen vessels a tap, put them to the proof, whether haply they be cracked and give a dull sound: see whether they ring full and clear, see whether charity be there. Thou takest thyself away from the unity of the whole earth, thou dividest the Church by schisms, thou rendest the Body of Christ. He came in the flesh, to gather in one, thou makest an outcry to scatter abroad. This then is the Spirit of God, which saith that Jesus is come in the flesh, which saith, not in tongue but in deeds, which saith, not by making a noise but by loving. And that spirit is not of God, which denies that Jesus Christ is come in the flesh; denies, here also, not in tongue but in life; not in words but in deeds. It is manifest therefore by what we may know the brethren. Many within are in a sort within; but none without except he be indeed without.
14. Nay, and that ye may know that he has referred the matter to deeds, he saith, "And every spirit, qui solvit Christum, which does away with Christ that He came in the flesh, [2343] is not of God." A doing away in deeds is meant. What has he shown thee? "That denieth:" in that he saith, "doeth away" (or, "unmaketh"). He came to gather in one, thou comest to unmake. Thou wouldest pull Christ's members asunder. How can it be said that thou deniest not that Christ is come in the flesh, who rendest assunder the Church of God which He hath gathered together? Therefore thou goest against Christ; thou art an antichrist. Be thou within, or be thou without, thou art an antichrist: only, when thou art within, thou art hidden; when thou art without, thou art made manifest. Thou unmakest Jesus and deniest that He came in the flesh; thou art not of God. Therefore He saith in the Gospel: "Whoso shall break [2344] one of these least commandments, and shall teach so, shall be called least in the kingdom of heaven." [2345] What is this breaking? What this teaching? A breaking in the deeds and a teaching as it were in words. [2346] "Thou that preachest men should not steal, dost thou steal?" [2347] Therefore he that steals breaks or undoes the commandment in his deed, and as it were teaches so: "he shall be called least in the kingdom of heaven," i.e. in the Church of this present time. [2348] Of him it is said, "What they say do ye; but what they do, that do not ye. [2349] But he that shall do, and shall teach so, shall be called great in the kingdom of heaven." From this, that He has here said, fecerit, "shall do," while in opposition to this He has there said solverit, meaning non fecerit, "shall not do, and shall teach so"--to break, then, is, not to do--what doth He teach us, but that we should interrogate men's deeds, not take their words upon trust? The obscurity of the things compels us to speak much at length, chiefly that that which the Lord deigns to reveal may be brought within reach even of the brethren of slower understanding, because all were bought by the blood of Christ. And I am afraid the epistle itself will not be finished during these days as I promised: but as the Lord will, it is better to reserve the remainder, than to overload your hearts with too much food.
