The revised Charta Oecumenica is no longer merely an ecumenical text awaiting reception. European church leaders are now putting its programme into practice. Read beside Pius XI’s Quas Primas and Mortalium Animos, its language about peace, mission, Eucharistic fellowship and “visible unity” exposes a profound change in the way Catholic claims are being expressed.
The one-page appeal for peace issued after last week’s CCEE–CEC meeting in Germany is not the important document. The important document is the one the participants had gathered to implement. From 9 to 11 September, representatives of the Council of European Bishops’ Conferences and the Conference of European Churches met in Frankfurt and Darmstadt with the reception of the revised Charta Oecumenica and “synodality” across Catholic, Orthodox and Protestant traditions explicitly at the centre of their deliberations.¹ The meeting was therefore not another ecumenical courtesy call which happened to end with a plea for peace. It belonged to an organised reception of a document intended to shape how Europe’s churches pray together, speak together, evangelise together and understand the unity towards which they say they are moving.
The Charta itself is remarkably candid about its status. It has “no magisterial or dogmatic character” and is not legally binding under Church law. Yet the very same passage says that it is intended to promote an ecumenical culture of dialogue and cooperation “at all levels of church life” and to provide agreed criteria for that culture. Participating bodies are encouraged to use, adapt and implement it according to local circumstances.² This tells us precisely where the document expects to exercise influence. It does not propose to define doctrine. It proposes to form practice. CCEE now describes it as a key reference document for cooperation, dialogue and common Christian witness and has called for its reception through common prayer, shared witness and formation.²
Nuntiatoria warned when the revised Charta appeared last November that its significance would not necessarily lie in explicit contradiction of Catholic dogma. The more interesting possibility was an ecumenical operating system in which unresolved dogmatic differences remained on paper while common prayer, common witness, common social action and a common ecclesiastical vocabulary steadily expanded around them.³ Frankfurt matters because that process is no longer hypothetical. The document is being received.
Its ecclesiology therefore requires more than a benevolent glance. The introduction speaks of Christ’s “one universal Church, which manifests in various local churches”, then invites churches, church councils, ecumenical bodies and initiatives to associate themselves with the programme.² There is nothing objectionable in speaking of the universal Church manifested in particular Churches when the terms are being used in their Catholic sense. The difficulty is that the Charta places bodies of very different sacramental and ecclesiological character within the same elastic vocabulary of “churches”.
Catholic doctrine does not do that without qualification. Dominus Iesus deliberately distinguished the separated Eastern Churches, which possess apostolic succession and a valid Eucharist and are therefore true particular Churches, from those Christian communities which have not preserved valid episcopacy and the genuine substance of the Eucharistic mystery and consequently are not Churches “in the proper sense”.⁴ The distinction is not semantic housekeeping. It concerns what the Church is, whether sacramental priesthood remains, whether Eucharistic sacrifice remains, and whether apostolic succession remains. To erase the distinction in ordinary ecumenical speech is to make agreement sound considerably more advanced than Catholic theology permits.
The Charta itself acknowledges differences over “the Church, the sacraments, and ministry”. Those are not details at the edge of an otherwise complete unity. They concern the Church’s constitution, Holy Orders, Eucharist and ecclesial authority. Yet the document immediately declares that what the participating communities share is “deeper and greater than all that separates us”, and commits them to pursue visible unity through mutual recognition of Baptism, Eucharistic fellowship, common witness and service.² The question is unavoidable. By what Catholic measure has it been established that what is already shared is greater than disagreement over the Church, sacraments and ministry instituted by Christ?
The difficulty becomes sharper when the Eucharist appears. The participating bodies commit themselves “to continue moving towards mutual Eucharistic hospitality and fellowship”.² “Hospitality” is an extraordinarily effective word. Its opposite sounds ungenerous before the theology has even been discussed. But the Blessed Sacrament is not denominational hospitality. Eucharistic communion manifests ecclesial communion.
St John Paul II stated the order precisely in Ecclesia de Eucharistia. The Eucharist presupposes an existing communion in faith, sacraments and ecclesiastical government; it cannot become the instrument by which that communion is manufactured.⁵ Catholic law allows certain carefully delimited sacramental exceptions. Those exceptions do not overturn the principle. Where faith concerning the Eucharist, Holy Orders and ecclesial government remains contradictory, movement towards “Eucharistic hospitality” cannot simply be treated as the next natural stage of warmer relations. The Catholic order is the reverse: unity in the Faith makes full sacramental communion possible.
At this point Mortalium Animos ceases to look like an artefact from an extinct ecclesiastical world. Pius XI was addressing Christians who also wished to end inherited hostility, gather believers around what they held in common and present a stronger Christian witness before an increasingly unbelieving society. His objection was not to Christian charity. It was to the ecclesiology required to make the project work.
Christ, Pius insisted, had not left behind a federation of Christian communities holding incompatible doctrines and waiting gradually to discover their corporate unity. He founded a visible Church possessing unity of faith, government and sacramental life. Pius therefore asked how communities which contradicted one another concerning Tradition, hierarchy, transubstantiation, Eucharistic sacrifice and other revealed truths could constitute a single Christian federation. His answer was uncompromising: the Church requires one teaching authority, one law of belief and one Christian faith.⁶
It would be facile merely to reproduce the disciplinary rules of 1928 and behave as though Vatican II had never occurred. Catholic ecumenical practice did develop. Unitatis Redintegratio encourages dialogue, cooperation and appropriate common prayer, and acknowledges real elements of sanctification and truth among separated Christians. But the Council simultaneously warned against false irenicism, by which Catholic doctrine is obscured or its certain meaning weakened.⁷ Nor did subsequent Catholic teaching replace the visible Church with a theory of denominations converging upon one another. Dominus Iesus was issued precisely because such interpretations had become plausible. The Church of Christ is not an ecclesial reality which exists nowhere in fullness today and must eventually be assembled from its separated parts.⁴
That leaves the serious question untouched by changes in ecumenical method. If the doctrine underlying Mortalium Animos remains Catholic doctrine, the destination of ecumenism cannot be indefinite reciprocal convergence. The unity for which Christians pray is not something Catholics believe vanished from history and must now be reconstructed. It already subsists visibly in the Catholic Church. The ecumenical task may properly include repentance for sins committed by Catholics, purification of memory, theological dialogue and recognition of genuine Christian goods beyond visible Catholic communion. It cannot require Catholicism to behave as though the identity of the Church remains an open question.
The Charta presses the matter further when it turns to evangelisation. A “credible witness”, it says, requires Christians to spread the Gospel “together and not in competition with each other”. It proposes agreements in common witness and evangelisation intended to avoid “harmful competition and the risk of fresh division”.² There are plainly corrupt forms of proselytism. Conversion must never be purchased, coerced or manipulated. The Charta is right to reject moral pressure and material inducement.² But an abuse of evangelisation does not settle what evangelisation is.
If the Catholic Church is what she claims to be, persuading a Protestant to enter full Catholic communion is not “harmful competition”. Since the Catholic Church judges Anglican orders invalid, Anglican ministry cannot simply be treated as one equivalent denominational expression of the same sacramental priesthood. Leo XIII’s Apostolicae Curae judged Anglican ordinations “absolutely null and utterly void”; the theological consequences do not disappear because ecumenical relations have subsequently become more cordial.⁸ If Catholic doctrine concerning Eucharistic sacrifice and transubstantiation is true, disagreement about them cannot be domesticated by an agreement that neighbouring communions will avoid winning one another’s adherents. Truth claims produce consequences.
A still more delicate problem appears in the treatment of Judaism. The Charta rightly condemns anti-Semitism and recognises the enduring mystery of Israel’s election. It then states that the first Covenant “has never been replaced by the new one” and commits participating churches to “renounce institutional proselytising mission to the Jews”, while remaining ready to offer personal testimony to Jesus. The wording is not incidental; it is one of the document’s explicit commitments.²
Catholic doctrine does not teach the crude proposition that God abandoned Israel and simply substituted another people in its place. St Paul’s insistence that the gifts and calling of God are irrevocable remains part of the inspired text. But the Catholic answer is fulfilment in Christ, not two religious economies proceeding indefinitely alongside one another. Jesus Christ is Israel’s Messiah. He is mediator of the New Covenant. The Old Testament promises reach their fulfilment in Him. The Apostolic commission to preach the Gospel is universal. The difficult question cannot therefore be evaded by administrative language: if the Gospel is for every creature, upon what theological principle does organised Christian mission acquire an ethnic exception?
The same habit of beginning from the largest possible common denominator appears in the sections dealing with Islam and other religions. Dialogue, peaceful coexistence, religious freedom and cooperation against violence are legitimate goods. Christians can and should defend the civil rights of Muslims and cooperate with them where the natural moral law permits common action. But Islam expressly rejects the Trinity and the divine Sonship which stand at the centre of the Christian Creed. Interreligious dialogue becomes worthwhile when those facts can be named without embarrassment. Once agreement becomes the governing objective, Christianity risks shrinking into one moral voice among several contributing “religious resources” towards a common social settlement.
The document’s treatment of peace brings the argument directly to Quas Primas. The Charta says much that is true. Peace is more than the absence of war. It requires truth, justice and solidarity. Christians must love their enemies, forgive, seek reconciliation and implore peace from God as His gift.² Its practical programme nevertheless resolves into encounter, dialogue, cooperation and the drawing upon of religious resources, where possible alongside other groups.
Pius XI began from somewhere considerably more demanding. In Quas Primas he attributed the calamities afflicting society to the expulsion of Christ and His law from private life and from public affairs. So long as individuals and States refused the sovereignty of the Saviour, he argued, there could be no secure prospect of lasting peace. Men must seek “the peace of Christ in the Kingdom of Christ”.⁹
That doctrine is not a pious way of saying that Christianity contributes useful values to political life. Quas Primas teaches that Christ possesses real sovereignty over individuals, families and States. His authority does not begin when a parliament votes to acknowledge it. Pius specifically complained of Christ’s exclusion from public affairs and insisted that social peace required the restoration of His reign. Christ is not one religious resource available to Europe’s peace process. He is King.⁹
This is why Quas Primas and Mortalium Animos belong together in judging the Charta. They were written by the same Pope only three years apart because their subjects arise from the same supernatural order. One concerns peace among men; the other unity among Christians. Neither begins from something absent which human cooperation must gradually construct. Christ already reigns, whether nations acknowledge Him or not. Christ has already founded His Church, whether separated Christians recognise her claims or not.
The Charta tends towards another grammar. Christian bodies move towards one another. They discern together, pray together, witness together, evangelise together and move towards Eucharistic fellowship. The ecumenical movement itself is described as “the work of the Holy Spirit”.² Properly understood, there need be nothing objectionable in saying that the Holy Ghost moves separated Christians towards unity. But the destination cannot remain ecclesiologically indeterminate. The Holy Ghost does not lead the Catholic Church to discover that her confession concerning herself was provisional. Ecumenism has a Catholic meaning only if movement towards unity is ultimately movement towards the fullness of Catholic faith, sacramental life and ecclesial communion. Otherwise the endless language of journeying eventually provokes the simplest question of all: journeying where?
The Charta is not made more harmless by the fact that much of it is humane, Christian and decent. Its condemnation of persecution is right. Its insistence upon protecting vulnerable people is right. Its condemnation of abuse is right. Its desire that Christians abandon hatred is right. Those acknowledgements sharpen rather than weaken the criticism. Serious theological change rarely arrives in a document announcing that Catholic doctrine has been abolished. More often the hierarchy of emphasis changes. Certain truths are repeated constantly. Others remain formally intact but become increasingly difficult to say.
European Christianity now possesses committees, consultations, bilateral dialogues, reception processes, common prayers, common social programmes and a shared vocabulary sufficiently elastic for bodies which contradict one another concerning priesthood, Eucharist, authority and the Church herself to speak together with considerable fluency. Meanwhile Europe becomes steadily less Christian. The Charta acknowledges the secularisation and declining influence of the churches, then proposes still deeper ecumenical sharing as part of the answer.² There is another possibility which deserves consideration. Perhaps Europe does not principally need Christianity to organise its divisions more efficiently. Perhaps it needs Christians once again to believe that the truths over which those divisions arose actually matter.
None of this requires sectarian hostility. Catholics can stand beside Protestants in defence of persecuted Christians, Orthodox believers in defence of unborn children, Jews against anti-Semitism and Muslims against terrorism. The natural law does not become false when recognised by someone outside the Church. Common work for a genuine temporal good does not require contempt for one’s neighbour. But cooperation is not communion. Civility is not ecclesiology. Peace-making is not doctrinal surrender.
The Charta Oecumenica deserves scrutiny because it repeatedly approaches those boundaries without securing them. “Churches” are gathered beneath an elastic common terminology. Differences concerning Church, sacraments and ministry are declared smaller than what is shared. Eucharistic hospitality becomes an objective. Evangelisation is reorganised to minimise “competition”. Institutional mission to the Jewish people is renounced. Christianity’s public vocation is increasingly expressed through common action with other confessions, religions and people of good will. Each proposition can be defended separately by careful qualification. Taken together, they describe an ecclesial mentality.
Pius XI described another one.
For Mortalium Animos, unity was not learning how contradictory communions might remain divided together. It was unity in revealed truth within the visible Church Christ founded. For Quas Primas, peace was not the product of religious contributions to a neutral settlement. It depended ultimately upon the recognition of the rights of Christ over men and nations.
The contrast is not between an angry past and a charitable present. It is between two accounts of what Christianity claims to be.
Europe needs peace. But peace has a King.
Christians need unity. But unity has a Church.
