2 John 1:1-3
"The elder to the chosen lady and her children, whom I love in truth; and not only I, but also all who know the truth, because of the truth which remains in us and will be with us forever: Grace, mercy, andpeace will be with us, from God the Father and from Jesus Christ, the Son of the Father, in truth and love."
John, the elder. Not a prophet, not a unique revelation making unique claims. Just the seasoned voice of one who has walked long with the truth and now writes out of pastoral concern. And he's writing to the family of God. Not an institution. Not a Magisterium. But an elect lady and her children. The church is first and last a people chosen in Christ, bound together by the truth that remains in them.
The weight of John's letter does not rest on his title; it rests on the truth that abides forever.
Jesus said the truth will never fail. He said,
"Heaven and earth will pass away, but My words will not pass away" (Matthew 24:35).
And Jesus went on to say,
"If you continue in My word, then you are truly disciples of Mine; and you will know the truth, and the truth will make you free" (John 8:31-32).
The truth remains and it will be with us forever because it is bound to the One who cannot lie and whose word cannot fail.
Even so, there is a threat to this truth.
"For many deceivers have gone out into the world, those who do not acknowledge Jesus Christ as coming in the flesh. This is the deceiver and the antichrist. Watch yourselves, that you do not lose what we have accomplished, but that you may receive a full reward. Anyone who goes too far and does not remain in the teaching of Christ, does not have God; the one who remains in the teaching has both the Father and the Son." (2 John 1:7-9)
Jesus Christ coming in the flesh is not a secondary detail. It is the heart of the teaching. To go beyond it, or to leave it behind, is to lose both the Father and the Son. Love in truth does not mean develop a soft tolerance of denial. And John pulls no punches.
2 John 1:10-12
"If anyone comes to you and does not bring this teaching, do not receive him into your house, and do not give him a greeting; for the one who gives him a greeting participates in his evil deeds."
Seem harsh?
UnChristlike?
It does, especially to modern ears trained to equate love with an open-handed welcome and disagreement with intolerance.
But you have to understand the context. In the first-century church, hospitality was not optional politeness. House churches depended on it. In the first century there were itinerant travelers claiming to be prophets and teachers. They moved from place to place, and the local believers were expected to receive them, feed them, and give them a place to stay.
They would drop in on these house churches and communities of faith. Claiming to have a word from God. Often for a price. The problem was that not every traveler who claimed a word from the Lord actually carried the truth. Some denied that Jesus Christ had come in the flesh. Others mixed the gospel with speculative ideas or used the circuit for personal gain.
Today the forms have changed, but the pattern remains recognizable. In our age we'd call them grifters. Clout chasers. Traveling podcasters of a sort. Traveling voices who monetize spiritual language, build platforms on partial truths or speculative systems, and expect affirmation from the people of God.
The issue John addresses is the same:
Does this person bring the teaching of Christ?
Has Jesus come in the flesh, or something else?
To open the door and extend the greeting to someone who denied that Jesus Christ had come in the flesh was to participate in the very deception that threatened the household.
Whether you're providing a space in the church, a guest room, a conference, or an internet feed, the danger remains the same. The issue is still partnership. Whether the teaching of Christ Jesus come in the flesh is being brought or set aside.
Imagine John today, from his cell in Patmos. Broadcasting his podcast. Reaching the churches of Jesus Christ around the world. speaking into a microphone instead of writing on parchment, still addressing the household of God rather than an institution. Still locating the church’s life in the truth that remains forever. Taking questions from the chat, and still measuring every voice by one question:
Does this bring the teaching of Christ, Jesus come in the flesh, or something else? Are they presenting a Jesus who is an illusion? A Christ who only appeared to have a real human body? Are they treating the cross was a theater of appearances? Are they emptying the cross of Jesus the man/God, like some kind of phantom?
I think today this problem still persists. Among the Muslim and Jewish traditions. And in many offsprings. The issue comes from a religious belief that cannot accept Jesus as the Son of God, both man and divine. The confession that Jesus Christ has come in the flesh, and that He is the Son of the Father, both truly man and truly God, remains a decisive point of division.
I believe, if I had to point out one scripture passage that should dispel these claims...
I'd share Proverbs 30:4 with them:
"Who has ascended into heaven and descended?
Who has gathered the wind in His fists?
Who has wrapped the waters in His garment?
Who has established all the ends of the earth?
What is His name or His Son’s name?
Surely you know!"
Agur’s questions in the proverbs are meant to expose our human limitation. And at the same time challenge our understanding of the divine nature. The proverb riddle does not explain how God can be man or come in the person of a Son; it simply sets the reality before us and leaves us without a merely human answer.
John’s testimony meets both sides of that challenge. The limitation is answered by revelation. The Son has come in the flesh, and those who receive this apostolic witness now know His name. The mystery of the divine nature is not dissolved but clarified; Jesus Christ is the Son of the Father, truly God and truly man. The One who gathers the wind and establishes the earth is the same One who entered our condition without ceasing to be who He is.
The truth that remains is the truth of this Son, known now because He has come in the flesh. And to know the Son’s name is to know who He is and the claim He makes. To refuse the teaching that Jesus Christ has come in the flesh is to refuse the name in which the Father is known.
Proverbs 30:4 ends with the challenge...
"Surely you know!"
The One who ascended and descended has done so by taking real flesh, real blood, and a real cross. The name is now known because the Person has been among us (Emmanuel).
