26. The apostle John says: “if anyone comes to you and does bring this doctrine, do not receive him into your house nor greet him” (2 John 10); what is the doctrine the apostle refers to?




The apostle John refers to the doctrine which holds that Jesus Christ has come in the flesh, for before saying those words, the apostle John said: “For many deceivers are entered into the world, who confess not that Jesus Christ is come in the flesh. This is a deceiver and an antichrist. Look to yourselves, that we lose not those things which we have wrought, but that we receive a full reward. Whosoever transgresseth, and abideth not in the doctrine of Christ, hath not God. He that abideth in the doctrine of Christ, he hath both the Father and the Son” (2 John 7-9). As you can see, it is a particular doctrine, that is, the doctrine which holds that Jesus Christ was a real man made of flesh and bones. In other words, it is the doctrine of the incarnation of the Son of God, as it is written: “And the Word was made flesh, and dwelt among us, (and we beheld his glory, the glory as of the only begotten of the Father,) full of grace and truth” (John 1:14), and again: “Let this mind be in you, which was also in Christ Jesus: Who, being in the form of God, thought it not robbery to be equal with God: But made himself of no reputation, and took upon him the form of a servant, and was made in the likeness of men: And being found in fashion as a man, he humbled himself, and became obedient unto death, even the death of the cross” (Philippians 2:5-8). Therefore it is the doctrine that holds the perfect humanity of Jesus Christ. This is a fundamental doctrine of Christianity, which is still denied by many people (who claim that Christ was a spirit or a ghost). I call this doctrine ‘a fundamental doctrine of Christianity’ because Christ could die on the cross for our sins in that He partook of flesh and blood. How could a spirit die on the cross for our sins? Therefore, to deny the humanity of Christ or that His body was a real human body made of flesh, bones and blood, leads inevitably to deny His atoning sacrifice. And obviously, this diabolical doctrine leads people to deny also the resurrection of Christ, which is the cornerstone of Christianity in that it took place for our justification - so if Jesus is not risen from the dead we would be still in our sins (1 Corinthians 15:17) and our faith would be futile -.

That’s why, therefore, the heresy which affirms that Jesus Christ did not come in the flesh is particularly dangerous and John warns us of those who teach it, not only in his second epistle but also in his first epistle, where we read: “Beloved, believe not every spirit, but try the spirits whether they are of God: because many false prophets are gone out into the world. Hereby know ye 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 that spirit of antichrist, whereof ye have heard that it should come; and even now already is it in the world. Ye are of God, little children, and have overcome them: because greater is he that is in you, than he that is in the world. They are of the world: therefore speak they of the world, and the world heareth them. We are of God: he that knoweth God heareth us; he that is not of God heareth not us. Hereby know we the spirit of truth, and the spirit of error” (1 John 4:1-6)
