What is the apostasy or falling away before Christ returns?

Question 10085.

A falling away must come before the day of the Lord, according to Paul, and Christians have argued about what he meant ever since. Some read it as a great abandonment of the faith in the last days. Others read it as a technical term for the Rapture itself. The two readings could hardly be further apart, and the difference matters for how you understand the sequence of end time events.

My own conclusion is that Paul is describing a deliberate, organised rejection of revealed truth in the period leading to the revealing of the man of lawlessness. I do not think the case for reading it as the Rapture succeeds, though I have friends who do and I understand why they find it attractive.

What Paul actually says

The verse is 2 Thessalonians 2:3: the day will not come unless the rebellion comes first, and the man of lawlessness is revealed. The ESV says rebellion, the King James says a falling away, and other versions say apostasy. All three are rendering the same Greek noun, and the definite article is present, so Paul has a particular event in mind rather than a general tendency.

Two things happen before the day of the Lord, then. There is a falling away, and there is the unveiling of a man. The order matters. The apostasy prepares the ground; the man of lawlessness harvests it. A world that has already turned its back on truth is precisely the world that will welcome a ruler who claims to be God.

It is worth noticing the definite article, because it changes the sense. Paul does not say a falling away but the falling away, which points to a particular defection his readers had already been taught about. He reminds them, do you not remember that when I was still with you I told you these things? Whatever this is, it was part of the basic instruction he gave to a young church during a stay of a few weeks. It mattered that much.

The meaning of apostasia

The noun is apostasia, from a verb meaning to stand away from. In the Greek Old Testament it describes rebellion against God, and in Acts 21:21 it is used of the charge that Paul was teaching Jews to forsake Moses. The word carries the idea of defection from a position once held. You cannot fall away from something you never stood on.

That is why I take the falling away to be religious rather than moral in a general sense. This is not the world becoming worse in the ordinary way. It is people who have known the truth, sat under it, perhaps professed it, turning round and walking in the opposite direction with their eyes open.

Paul describes the same pattern elsewhere. In later times some will depart from the faith by devoting themselves to deceitful spirits and teachings of demons (1 Timothy 4:1). People will not endure sound teaching and will accumulate teachers to suit their own passions. That drift is the falling away gathering pace.

Does the falling away mean the Rapture?

A number of respected teachers argue that apostasia here means a physical departure, and therefore refers to the Church being caught up. They point out that several early English versions rendered it departing, and that the related verb can mean to depart in a spatial sense.

I have weighed this carefully, and I cannot follow it. The noun apostasia is not used anywhere in the New Testament or the Greek Old Testament for a spatial departure; it consistently describes defection or rebellion. Paul had a perfectly good word for the catching up and used it in his previous letter. When the same writer addresses the same church about the same subject and switches to a word that means rebellion, the natural conclusion is that he means rebellion.

None of that damages the pretribulational position, which I hold firmly. The case for the Rapture preceding the Tribulation rests on the removal of the restraint, on the promise that we are not destined for wrath, and on the character of imminence. It does not need this verse, and I would rather hold a strong position with sound arguments than prop it up with a doubtful one.

Let me add one more consideration. If apostasia meant the Rapture here, Paul’s argument would run oddly. He is explaining why the day of the Lord cannot already have arrived, and his evidence is that two things have not yet happened. If the first of those were the departure of the Church, he would be telling people who were plainly still on earth that they could tell they were still on earth. That is not much of an argument, and Paul was a better reasoner than that.

Is the falling away already happening?

In one sense every age has seen defection, and the New Testament letters are full of names: Demas, who loved this present world, Hymenaeus and Alexander, those who went out from us because they were not of us. The mystery of lawlessness was already at work in Paul’s day, and so was the falling away in seed form.

What Scripture anticipates is an intensification and a consolidation, an organised religious apostasy that becomes the default position of a culture rather than the choice of individuals. I think we see the direction of travel in the Western church, where whole denominations have quietly abandoned the authority of Scripture, the exclusivity of Jesus and the reality of judgement while keeping the buildings and the vocabulary.

I say that without triumphalism. It is a grief, not a scoring point. But naming it honestly is part of a pastor’s job, and pretending a falling away is not happening does no one any favours.

What makes the modern version distinctive is its politeness. The falling away I see is rarely announced. Nobody stands up and renounces the faith. Instead a doctrine is quietly reinterpreted, then treated as optional, then described as a barrier to mission, and within a generation it has gone without anyone voting on it. Paul’s language of standing away from a position describes that process exactly. You do not have to slam a door to leave a building.

Falling away and eternal security

This is where people get frightened, so let me be plain. A believer who is truly in Jesus cannot be lost. Our security rests on the faithfulness of God, on the Father’s grip, the Son’s finished work and the Spirit’s sealing, not on the strength of our hold on Him. Nothing in the doctrine of a coming apostasy overturns that.

John gives us the key: they went out from us, but they were not of us, for if they had been of us they would have continued with us (1 John 2:19). Departure reveals what was always the case rather than undoing what was true. The falling away exposes profession that was never possession.

If you are anxious about this, that anxiety is itself a hopeful sign. The apostate is not the man losing sleep over whether he might fall away. He is the man who no longer cares.

How to guard against it

Guarding is ordinary work. Keep reading the Scriptures for yourself rather than living on other people’s summaries of them. Stay planted in a local church where the Bible is opened and where somebody would notice if you disappeared. Watch what you find yourself excusing, because a falling away rarely begins with a doctrinal decision. It begins with a preference.

Watch your teachers too. Paul’s answer to a coming apostasy was not a bunker but sound doctrine held in love. Test what you hear against Scripture, and be suspicious of teaching that flatters you. The truth is rarely as comfortable as we would like.

Be careful, too, about the company your soul keeps. A falling away is almost always social before it is theological. People drift where their friends are drifting, and they find arguments afterwards to justify where they have already arrived. That is not cynicism, it is observation, and it explains why the New Testament puts such weight on belonging to a body of believers rather than on private conviction alone. Apostasy rarely begins with a book.

So, now what?

Take this as a warning and a comfort at once. A falling away is coming, so do not be shocked when respected names abandon what they once preached. It is written into the shape of the age. Grieve it, but do not let it shake you.

And hold on to the promise underneath. The Lord knows those who are His, and the foundation stands firm. If you have trusted Jesus, you are not on the list of those who fall away, and no coming apostasy can put you there. What would it look like this week to feed the faith you already have rather than fret about losing it?

One last encouragement. The same Paul who warned about the falling away told Timothy that God’s firm foundation stands, bearing this seal: the Lord knows those who are His. Notice which way round that reassurance runs. Our security does not rest on our ability to identify who is genuine, including ourselves on a bad day. It rests on His knowledge, and His knowledge is not revisable.

Let no one deceive you in any way. For that day will not come, unless the rebellion comes first, and the man of lawlessness is revealed, the son of destruction.
