Beloved, believe not every spirit, but test the spirits whether they are of God: because many false prophets are gone out into the world.

Most dearly beloved, &c. By the word spirit he means suggestion, inspiration, impulse, teaching or rather the person himself who suggests, inspires, teaches, &c. He means, do not give credit to everything which every teacher or adviser teaches and advises you. For there are diverse, yea contrary teachers, who are influenced by contrary spirits. Wise and orthodox teachers are moved by the good Spirit of God, wicked and erring teachers, such as heretics, by the evil spirit of the devil. And Song of Solomon , as Dionysius says, the good, or evil spirit, speaks by the mouth of doctors. Thus the devil, speaking by the mouth of the serpent, tempted and seduced Eve. There is a reference to sailors, who do not trust every spirit, or breath, or blast of wind, for if they did, they would miss their destined port, and would be often driven upon rocks and quicksands. Wherefore he bids us examine and search out by what spirit teachers are led before we give them our confidence. This is the forewarning which Paul gives1Tim4: i. "The Spirit speaketh expressly," &c.
But try ye (as gold is tried by the Lydian stone), Syriac, discern Ye between: because, as saith Ambrosiaster, "unclean spirits are wont by imitation to say good things deceitfully, and so to superinduce evil things, that by means of the things which are good the evil things may be accepted, so that they should be supposed to be the words of one and the same spirit, and that they should not be discerned the one from the other, but that which is unlawful should be commanded by that which is lawful."
Moreover, that Lydian stone by which spirits and doctrines are to be tried is not every one"s own private spirit. For this may be, and often Isaiah , moved by the devil, as when one is contrary to another: (for from this have been generated as many sects conflicting with themselves, as the poets have feigned heads to Cerberus* but it must be the doctrines of the Apostles and the Church. For this is the certain and common heritage of all the faithful. Such was that teaching which S. John suggests as suitable and necessary for his own age, saying, "Every spirit which confesseth that Jesus Christ is come in the flesh is of God." Falsely therefore do the heretics argue from this passage that their heresies ought to be tried and examined. For they have been examined and condemned by the Church. So there is no need, nor indeed is it right for each private Christian to try them. Thus S. Jerome says to Pammachium, "Why after4000 years dost thou strive to teach what we have not known before? Has the Christian world been without this doctrine until to-day?" And S. Augustine says (contra Crescen. lib2. c35), "The Church, ye say, hath perished, and ye show of whom ye are sprung." And Vincent of Lerius says, "If novelty is to be shunned, antiquity is to be held fast: if novelty is profane, antiquity is sacred." And Primasius says acutely, "The spirits have been already tried by the Church. Why dost thou wish to prove that which hath been already disproved?"
Moraliter:S. John here teaches that no Christian ought to trust all his inward motions, impulses, inspirations, desires, reasons seemingly good, but ought carefully to examine their origin and their author. Thus a man of a melancholy temperament perceives motions and impulses to sadness, pusillanimity, suspicion. Let him not give way to them. For if he examine their origin, he will find that they arise from the evil spirit of melancholy, which is false and deceitful. The choleric man is agitated by blasts of anger, revenge, indignation. He thinks he is moved by a zeal for justice. But let him with a calm mind and reason search into their origin, and he will find they spring from the evil spirit of bile and anger. Thus when the Samaritans would not receive Christ, and James and John said, "Lord, wilt thou that we call down fire from heaven to consume them?" He answered, "Ye know not what spirit ye are of." For ye think ye are moved by the Spirit of God, and ye are acted upon by the human spirit of impatience. Thus many think they are led by the Spirit of God, that is to say by the Spirit of truth, sobriety, chastity, charity; whereas, if they would thoroughly and sincerely, as in the presence of God, examine the ground of their heart, they would find that they are led by the spirit of the devil, that is to say, of vanity, gluttony, lust, &c. Wherefore in those blasts, passions, and tumults of the mind, the judgment ought to be suspended. And most especially ought the Holy Spirit to be invoked, that He would bestow upon us the gift of discernment of spirits.
In this is known the Spirit of God. He means, This is the pledge of the true faith and doctrine, which the Spirit of God teaches and suggests, that is to say, every spirit which confesseth that Jesus Christ is come in the flesh is of God. This therefore was in the time of S. John as it were the pledge and the symbol of the true Christian faith, namely, to believe and confess the Incarnation of Christ the Son of God, and the rest of the Dispensation in the flesh. For all the heretics and heresies at that time fought against this article of the faith as something new and strange. Some denied Christ"s Divinity, and taught that He was a mere Prayer of Manasseh , as Cerinthus and others denied Christ"s humanity, and said that it was not real, but a phantasm. Such were Simon Magus, Manes, and many others.
S. Augustine adds that all heresies reject Christ Incarnate, because they oppose His doctrine, Church, Sacraments, Pontiff, or priestly order, which He established. Thus Pelagius, in denying the grace of Christ, although with his lips he confessed His Incarnation, in reality overthrew it, because the Incarnation of Christ took place for the very purpose of giving us grace. You may say the same of Luther, Calvin, and the rest of the sectaries. For which cause S. John calls all heresiarchs antichrists, because they are all opposed to Christ"s doctrine and His Church.
Mystically: Å’cumenius understands this confession of the coming of Christ in the flesh "to be made not with the tongue, but by works." For not many heretics only, but bad Catholics also, confess Christ in words, but deny Him by their deeds. It means, he who confesses Christ, both by living rightly, as well as by believing truly concerning Him, this man is of God. So Bede. As S. Augustine says, "Let us confess that Christ has come in the flesh, both by speaking the truth in words, and by living well in deeds. For if we confess in words, and deny by deeds, the faith of such is very nigh the faith of devils."
