DOGS RETURNING TO VOMIT: WHY THE MAINLINE RECONQUISTA WILL FAIL

By David W. Virtue, DD I www.virtueonline.org I July 2, 2026

There is a movement afoot — earnest, energetic, and ultimately doomed — to reconquer the mainline Protestant denominations for the gospel they long ago abandoned. Its advocates speak of renewal, revival, and reclamation. They invoke the memory of better days. They organize conferences, publish manifestos, and recruit orthodox clergy willing to remain inside dying institutions as a remnant witness.

Scripture has a word for this. It is not an encouraging one.

"As a dog returns to its vomit, so fools repeat their folly." — Proverbs 26:11

The Apostle Peter, never one for diplomatic understatement, reaches for this same image when describing false teachers who have known the truth and turned from it: "A dog returns to its own vomit, and a sow, after washing, returns to wallowing in the mire" (2 Peter 2:22). Peter is not speaking of pagans who never knew better. He is speaking of those who escaped the world's corruption, tasted the knowledge of the Lord and Savior Jesus Christ — and went back.

That is the precise spiritual condition of the mainline denominations. And it renders the Reconquista project not merely difficult, but theologically misconceived.

THE RECONQUISTA IMPULSE

The impulse is understandable. The Episcopal Church, the Presbyterian Church USA, the United Methodist Church, the Evangelical Lutheran Church in America — these were once institutions that preached the atoning death of Christ, held Scripture as authoritative, and sent missionaries to the ends of the earth. Their hymnody was orthodox. Their seminaries trained men who believed what they taught. Their pews were full.

The collapse came gradually, then catastrophically. Higher criticism gutted biblical authority. The sexual revolution reshaped their anthropology. Progressive politics replaced prophetic proclamation. Denominational bureaucracies became self-perpetuating engines of theological liberalism, insulated from congregational accountability and impervious to reform.

Now a generation of orthodox believers, refusing to concede the institutional real estate without a fight, has mounted what some are calling a Reconquista — a recovery movement aimed at retaking from within what was surrendered without resistance.

The historical analogy is instructive, but not in the way its proponents intend.

WHAT THE ORIGINAL RECONQUISTA ACTUALLY PRODUCED

The Spanish Reconquista lasted nearly eight centuries — from 718 AD to 1492. It succeeded militarily. It failed spiritually. The recovered territories did not produce a renewed Christendom so much as an Inquisition. The instruments forged for reconquest became instruments of coercion. The church that emerged was not purified by the struggle; it was deformed by it.

Seven hundred years of effort. And the result was the Spanish Inquisition.

If that is the template for mainline renewal, orthodox believers should think carefully before enlisting.

WHY INSTITUTIONS CANNOT BE UNCONVERTED

The deeper problem is not strategic but biological — which is precisely what the Proverbs image captures. The dog returns to its vomit not because it has made a rational calculation but because it is following its nature. Instinct drives it. Veterinarians confirm the behavior is not pathological — it is simply what dogs do, inherited from wolves who regurgitated food for their pups or cached it for later consumption. The dog is being fully, authentically itself.

So are the mainline denominations.

Decades of theological liberalism have not merely infected these institutions — they have become these institutions. The seminaries that train their clergy, the bureaucracies that govern their policies, the hermeneutical assumptions that shape their preaching, the progressive ideology that drives their social witness — these are not deviations from an otherwise healthy organism. They are the organism. The DNA has been rewritten.

You cannot renew what has been replaced.

THE RENEWAL CYCLE

The pattern is by now depressingly familiar. A mainline denomination, alarmed by membership hemorrhage and cultural irrelevance, launches a renewal initiative. Evangelical language is borrowed. Scripture is quoted with unaccustomed conviction. A charismatic bishop or energetic pastor becomes the public face of recovery. Attendance ticks upward in selected parishes. Hope is kindled.

Then the tide turns. The renewal leaders retire, move on, or are marginalized by the bureaucratic apparatus they never fully controlled. The denominational machinery — committees, commissions, general assemblies, and their attendant ideological agendas — reasserts itself. The borrowed evangelical language is quietly retired. The trajectory resumes.

The Episcopal Church has run this cycle multiple times. So has the PCUSA. The UMC, after decades of failed renewal efforts, finally fractured — and the orthodox departed to form the Global Methodist Church, taking with them the painful lesson that institutional loyalty without theological integrity is not faithfulness but sentimentality.

Peter's warning applies with precision: it would have been better for them not to have known the way of righteousness than, after knowing it, to turn back (2 Peter 2:21). Institutions that have known orthodox Christianity and rejected it are not neutral territory awaiting reclamation. They are under judgment. Their condition is worse than if they had never been evangelical at all.

WHAT FAITHFULNESS ACTUALLY REQUIRES

None of this is to disparage the courage of those who have chosen to remain and contend. There is a legitimate witness in staying. But it must be undertaken with clear eyes, not with the illusion that the institution can be turned around from within by sufficiently determined orthodox minorities.

The orthodox Anglican witness learned this at enormous cost over thirty years of failed renewal efforts within the Episcopal Church — efforts by Episcopalians United, the American Anglican Council, the Network of Anglican Communion Dioceses and Parishes, and others — before the realignment produced ACNA. The lesson was not that the effort was wrong, but that the institution was not reformable. At some point, faithfulness required departure.

The Reconquista model assumes that what was lost can be recovered by institutional means — by electing the right bishops, passing the right resolutions, winning the right votes at general conventions. But the mainline crisis is not primarily institutional. It is spiritual. And spiritual problems are not solved by parliamentary procedure.

THE GOSPEL THEY ABANDONED

What the mainline denominations abandoned was not merely a set of doctrinal propositions. They abandoned the gospel — the announcement that Jesus Christ died for sinners, rose bodily from the dead, and will return to judge the living and the dead. They abandoned the authority of Scripture as the norming norm of Christian faith and life. They abandoned a biblical anthropology that understands human beings as made male and female in the image of God, fallen, and in need of redemption.

These are not peripheral matters that can be negotiated back into institutional life through clever strategy. They are the substance of Christian faith. Without them, what remains is not a church in need of renewal. It is a social organization wearing ecclesiastical clothing.

Dogs return to their vomit. It is what they do. The mainline denominations will continue their trajectory — shrinking, aging, compromising, and celebrating their own decline as prophetic progressivism — because that is now their nature.

The orthodox have not abandoned the gospel by leaving these institutions. They have honored it. The Reconquista will not succeed because the territory it seeks to recover has not merely been occupied by the enemy. It has been given over to him — willingly, repeatedly, and with theological sophistication.

Scripture told us exactly what this would look like. Peter warned us. The only question is whether we will believe him.
