Seeds in Winter: Mercier's Bet on Christian Unity

In 1921, a Belgian cardinal opened his doors to Anglican theologians and began one of the most unlikely conversations in modern Church history. What drove him was not diplomacy — it was faith that God's desire for Christian unity was already at work in the world.

July 1, 1921

The city of Malines, Belgium, sits about fifteen miles north of Brussels, and in December 1921 its archbishop's residence was cold in the way that old stone buildings are cold — a chill that settles into the walls and stays. Into that house came a small group of Catholic and Anglican theologians, uncertain what they were doing there, invited by a cardinal who was quite certain that God had arranged the meeting.

Cardinal Désiré Mercier was already famous. He had spent the years of German occupation during the First World War writing pastoral letters that stiffened Belgian resistance, and Rome and Brussels both regarded him as a man of granite. But the gathering he hosted that December was something quieter and, in some ways, stranger than any wartime confrontation. He was sitting down with Anglicans — specifically with Lord Halifax, the veteran English ecumenist, and with theologians including Walter Frere of the Community of the Resurrection — to talk about whether the split between Canterbury and Rome might, someday, be healed.

The official answer from both sides was, effectively, not yet. The Holy See had not authorized the talks. Canterbury had not authorized them either. The conversations were, as they have been described in historical accounts including the summary available through Wikipedia's article on the Malines Conversations, deliberately unofficial — which is another way of saying that the institutions responsible for reunion were not yet willing to risk the embarrassment of failure. Mercier was willing.

What Faith Looks Like in a Cold Parlor

There is a tendency to describe ecumenical dialogue as a kind of strategic patience, as though the participants were playing a long chess game and simply needed to wait for the right moment to press their advantage. That framing misses what was actually happening in Malines. Mercier was not maneuvering. He believed, on theological grounds, that the unity of Christians was God's will — and that God's will was not merely a pious aspiration but a force operating in history, whether the institutions recognized it or not. The conversations continued across four sessions through 1925 because Mercier treated them as obedience to a reality he could not yet see, not as a calculated investment in a visible outcome.

This is the classical Catholic understanding of faith, and it is harder to live than it sounds. The Catholic Christian anthropology that the Church has developed over centuries describes the human person as created for communion — with God, and through God, with one another. The divisions of the Reformation were, on this account, a wound in the Body of Christ, not a natural state of affairs. To accept them as permanent was to doubt whether the Redemption had any power over history. Mercier's faith was specific: he trusted that the same Christ who had prayed for unity in John 17 was still praying, and that the prayer would eventually be answered.

Mercier reportedly spoke of the Malines talks as seeds planted in ground whose harvest belonged to God, not to the men who dug.

The Fallen dimension of the Catholic account of the person is visible here too, though it appears in the resistance the conversations met. Institutions, even sacred ones, tend toward self-preservation. Rome worried about scandal and misinterpretation. Canterbury worried about Protestant alarm. Both worries were legitimate, as far as they went. The difficulty was that legitimate prudence, carried too far, can become a rationalization for doing nothing that God has not yet guaranteed will succeed. Mercier was willing to act inside the uncertainty.

The Question of Whether History Cooperates

The 1920s were not obviously a decade suited to reconciliation between churches. The war had redrawn Europe's map and left its institutions shaken. Catholic-Protestant suspicion in England and on the continent was still culturally embedded in ways that went well below the level of theology. Lord Halifax was an aristocratic Anglican who had spent decades hoping for reunion, and even he knew the obstacles were enormous. Walter Frere, a scholar of liturgy and a careful thinker, understood that the doctrinal distances between the two communions were real and not easily collapsed by good feeling.

What the conversations produced was not reunion. They produced a series of papers, a set of relationships, and a precedent. The formal ecumenical movement that would eventually generate the Second Vatican Council's Decree on Ecumenism in 1964 and the Anglican-Roman Catholic International Commission in 1970 had many parents, but Malines was among them. Mercier did not live to see any of it. He died in January 1926, a year after the final session.

The Catholic account of the human person holds that we are not self-sufficient reasoners who calculate our way to God. We are creatures who receive — grace, truth, love — and whose deepest capacity is the act of trusting what we have been given before we can verify it fully. This is not irrationalism. It is the recognition that some realities are larger than the evidence available at any given moment, and that acting on them is how they begin to become visible.

Mercier, sitting in his stone residence in Malines in December 1921, pouring tea for men whose orders Rome did not recognize, was doing something that looked, by ordinary institutional logic, like a minor eccentricity of a distinguished old cardinal. By the logic of faith, he was cooperating with something already in motion.

The papers from those sessions are still in the archives. The cold has long since left the building.
