Chapter 4
1 John 4:1-3
1. Beloved, believe not every spirit, but try the spirits whether they are of God: because many false prophets are gone out into the world.
2. Hereby know ye the Spirit of God: Every spirit that confesseth that Jesus Christ is come in the flesh is of God:
3. And every spirit that confesseth not that Jesus Christ is come in the flesh is not of God: and this is that spirit of antichrist, whereof ye have heard that it should come; and even now already is it in the world.
He returns to his former doctrine, which he had touched upon in the second chapter; for many (as it is usual in new things) abused the name of Christ for the purpose of serving their own errors. Some made a half profession of Christ; and when they obtained a place among his friends, they had more opportunity to injure his cause. Satan took occasion to disturb the Church, especially through Christ himself; for he is the stone of offense, against whom all necessarily stumble who keep not on the right way, as shewn to us by God.
But what the Apostle says consists of three parts. He first shews an evil dangerous to the faithful; and therefore he exhorts them to beware. He prescribes how they were to beware, that is, by making a distinction between the spirits; and this is the second part. In the third place, he points out a particular error, the most dangerous to them, he therefore forbids them to hear those who denied that the Son of God appeared in the flesh. We shall now consider each in order.
But though in the passage this reason is added, that many false prophets had gone forth into the world, yet it is convenient to begin with it. The announcement contains a useful admonition; for if Satan had then already seduced many, who under the name of Christ scattered their impostures, similar instances at this day ought not to terrify us. For it is the case perpetually with the Gospel, that Satan attempts to pollute and corrupt its purity by variety of errors. This our age has brought forth some horrible and monstrous sects; and for this reason many stand amazed; and not knowing where to turn, they cast aside every care for religion; for they find no more summary way for extricating themselves from the danger of errors. They thus, indeed, act most foolishly; for by shunning the light of truth, they cast themselves into the darkness of errors. Let, therefore, this fact remain fixed in our minds, that from the time the Gospel began to be preached, false prophets immediately appeared; and the fact will fortify us against such offenses.
The antiquity of errors keeps many, as it were, fast bound, so that they dare not emerge from them. But John points out here all intestine evil which was then in the Church. Now, if there were impostors mixed then with the Apostles and other faithful teachers, what wonder is it, that the doctrine of the Gospel has been long ago suppressed, and that many corruptions have prevailed in the world? There is, then, no reason why antiquity should hinder us to exercise our liberty in distinguishing between truth and falsehood.
1 Believe not every spirit When the Church is disturbed by discords and contentions, many, as it has been said, being frightened, depart from the Gospel. But the Spirit prescribes to us a far different remedy, that is, that the faithful should not receive any doctrine thoughtlessly and without discrimination. We ought, then, to take heed lest, being offended at the variety of opinions, we should discard teachers, and, together with them, the word of God. But this precaution is sufficient, that all are not to be heard indiscriminately.
The word spirit I take metonymically, as signifying him who boasts that he is endowed with the gift of the Spirit to perform his office as a prophet. For as it was not permitted to any one to speak in his own name, nor was credit given to speakers but as far as they were the organs of the Holy Spirit, in order that prophets might have more authority, God honored them with this name, as though he had separated them from mankind in general. Those, then, were called spirits, who, giving only a language to the oracles of the Holy Spirit, in a manner represented him. They brought nothing of their own, nor came they forth in their own name, but the design of this honorable title was, that God’s word should not lose the respect due to it through the humble condition of the minister. For God would have his word to be always received from the mouth of man no otherwise than if he himself had appeared from heaven.
Here Satan interposed, and having sent false teachers to adulterate God’s word, he gave them also this name, that they might more easily deceive. Thus false prophets have always been wont superciliously and boldly to claim for themselves whatever honor God had bestowed on his own servants. But the Apostle designedly made use of this name, lest they who falsely pretend God’s name should deceive us by their masks, as we see at this day; for many are so dazzled by the mere name of a Church, that they prefer, to their eternal ruin, to cleave to the Pope, than to deny him the least part of his authority.
