Calvin
- 4:1
- Many abuse the name of Christ for their own ends. When these mix in the company of believers, there is an increased potential for damage to the body. John first warns of the general danger, puts forth the protective test of the spirits, and then points out a particularly egregious error - that of denying the Christ. In noting that falsehood has accompanied the truth of the Gospel from the start, the errors of our own day shouldn't terrify us, or lead us to give up on religion. This also serves to warn us that the antiquity of any particular doctrine is not sufficient to qualify it as valid. We must be discriminating in what we subscribe to as doctrine, not running from the confusion of ideas, but sifting them by the Holy Spirit within to discern truth from error. Calvin views the term 'spirit' as a title given the New Testament prophets - indicating that their messages were to be purely as dictated to them by the Holy Spirit, containing none of themselves. Satan, of course, imitates the truth by calling his deceivers prophets as well. The title of the teacher or prophet is also insufficient to validate the message. Again, the message must be filtered by the Holy Spirit to strain out the truth from the lies. Every message must be tested against God's Word, and against the Spirit. Scripture alone is actually insufficient to the task, because we are not able to understand its meaning without the aid of God's Wisdom within us. Thus, all must be taken prayerfully to God - to the Holy Spirit who leads us into all truth - in consideration of His revealed Word. The assembly of the saints serves to confirm the truth we have discerned, and reject any errors we may have thought true. By the grace of God alone are such a diverse group able to arrive at unity. The stamp of a church council is still insufficient to validate the truth - for it must be tested whether they came to their answer at God's feet or of their own imaginations.
- 4:2
- Christ is the aim of the believer, and the block that all deceivers stumble on. "As long then as we abide in Christ, there is safety; but when we depart from him, faith is lost, and all truth is rendered void." That Christ "came" indicates that He existed before His life here - indeed from all eternity with the Father. That he came "in the flesh" indicates that He became a real man, a brother to us. In discussing His having come, we mustn't forget why He came - for He came with purpose. Thus the test of the teacher hangs on him understanding all that is implied in Jesus Christ our Lord. Each heresy in turn fails on at least one point - either His divinity, or His humanity, or His unique unmatchable role. Since all true doctrine points to and depends on the full truth of Christ, this ought to be our focus.
- 4:3
- Knowing his readers to be well aware of the dangers of Antichrist, he points to the dire foulness of those who taught a reduced Christ by pointing out their association with that antichristian spirit. Antichrist was/is present inasmuch as it carries on its work in secret, as it were; spreading its corruptions as it can. Antichrist will be present in the future as a full-blown departure of the world from God, exalting itself above all else.
- 4:4
- We are assured of victory in spite of the seemingly overwhelming attack. For we know that Christ wins, and we are His. This truth applies to all of our walk in this world - that when we join in the battle with God's weapons rather than our own, the victory is already assured! No matter the means Satan may use to deceive us, we can - by God's working through us - stand firm. Our own strength would prove insufficient for us even to consider starting to fight, for we would believe ourselves lost from the outset. But God - and God alone - is greater, and provides us with the power to stand and to overcome.
- 4:5
- The world - being ruled by falsehood and accustomed to falsehood - readily embraces the lies proffered by such false teachers. This shouldn't surprise or dismay us.
- 4:6
- The faithful teacher - the one who is of God - will demonstrate in his own life the truth which he speaks. His life will serve as testimony to his message. This, the false teacher cannot claim. The rejection of the Gospel by so many does nothing to diminish its truth. Not all who claim to be of God are so. Obedience to His word is a necessary accompaniment to confession of His name. We cannot claim to be unable to properly judge His word and yet claim to be His, for if we are His, His Spirit abides in us and provides us with the wisdom needful to judge. Rejection of the truth indicates a lack of election, for hearing is an inward act of the heart, and comes of faith. The test of the teacher, then, lies in both the source of his message (God or the world), and the character of those who take to his teachings (godly or worldly). Since, however, all teachers true and false lay claim to being oracles of God's revelation, we must - relying prayerfully on the guidance of the Holy Spirit - consult God's revealed Word, seeking to understand what it reveals with regard to each teaching; judging thereby the source of the lesson, whether it be truly God, or the world in disguise.
