The tweet in Spanish from @Pontifex_es about Algeria does not merely praise coexistence, social peace or cooperation between people of different religions. It goes much further. It states that "under the mantle of Our Lady of Africa, communion between Christians and Muslims is built." And that is exactly where the problem lies. Not in courtesy toward Muslims. Not in the desire for peace. Not in the possibility of civil collaboration. The problem lies in calling "communion" something that, in the Catholic sense, is not.
In the language of the Church, communion is neither a pleasant emotion nor a well-intentioned metaphor to designate that people get along reasonably well. Communion has an objective doctrinal content. The Catechism explains that the unity of the Church is assured by "visible bonds of communion": the profession of the same faith received from the Apostles, the common celebration of divine worship and the sacraments, and apostolic succession through the sacrament of order. This does not describe mutual sympathy. It describes actual membership in the same supernatural reality founded by Christ. If there is not the same faith, if there are not the same sacraments, if there is no ecclesial communion, speaking of "communion" ceases to be Catholic precision and becomes terminological confusion.
Catholic doctrine itself distinguishes quite clearly between non-Catholic Christians and adherents of non-Christian religions. With respect to separated Christians, the Catechism speaks of a "certain communion, though not perfect," founded on valid baptism and faith in Christ. This formulation itself shows that the word "communion" is not distributed indiscriminately. It applies, though in an imperfect manner, wherever there is baptismal incorporation into Christ and a real, though wounded, bond with the Church. This logic cannot be transferred without qualification to Islam, because Islam does not baptize in Christ, does not confess Jesus Christ as the Son of God, does not recognize the Trinity nor participate in the sacramental order of the Church. Between Catholics and Orthodox, one may speak of imperfect communion. Between Christians and Muslims, one may not.
Here it is worth anticipating the usual objection. Lumen gentium 16 or Nostra aetate 3 will be cited immediately, where the Council affirms that Muslims "adore with us one God, merciful," and that the Church looks upon them with esteem, recognizing in them elements of religious truth, a serious moral life, and the practice of prayer, almsgiving, and fasting. All of this is true. And precisely because it is true, it should be read in its entirety and not mutilated. The Council does not say that there exists ecclesial communion with Islam. It says something quite different: that there is a reference to the Creator, that there exist partial goods and truths, and that this justifies respect, dialogue, and collaboration. Furthermore, Nostra aetate recalls at the same time that the Church "proclaims and has the obligation to proclaim constantly Christ," in whom men find the fullness of religious life. That is, respect yes; indifferentism, no; dialogue yes; doctrinal dissolution, no.
The problem with the tweet is not, therefore, that it is too kind to Muslims. The problem is that it erases a conceptual boundary that the magisterium itself maintains. One thing is to recognize that a Muslim, as a rational creature, can sincerely seek God, live with moral integrity, and participate in certain goods that grace does not cease to sow in the world. Quite another thing is to present that situation as "communion." Because communion, for the Church, is born of Christ and leads to Christ. It does not spring simply from the common aspiration to dignity, love, justice, and peace. These aspirations are human and noble, but they do not in themselves constitute the supernatural communion of the Church. Reducing communion to an ethical consensus is emptying it of its specifically Christian content.
The key lies in not confusing levels. There can be social coexistence without communion of faith. There can be cooperation for justice without religious unity. There can be mutual esteem without sharing Christian revelation. One can even affirm, with the Council, that Muslims adore the one Creator God, in the sense that their religious intention is not directed toward a plurality of pagan gods, and at the same time steadfastly maintain that they reject essential truths of Christian faith: the Trinity, the divine filiation of Christ, the Incarnation and Redemption as the Church professes it. When that is forgotten, the difference between full truth and partial truth disappears beneath a sentimental fog. And that fog always favors error.
In fact, the Catechism expressly states that Christian faith cannot accept "revelations" that claim to surpass or correct the definitive Revelation given in Christ, and adds that this is the case with certain non-Christian religions. The phrase has a direct bearing on Islam, which presents itself historically as a subsequent revelation that corrects central elements of Christianity. This does not prevent respect toward Muslims as persons, but it does prevent dissolving the doctrinal difference under ambiguous expressions. If Christ is the full and definitive revelation of the Father, then one cannot speak lightly of religious communion where that fullness is denied.
Dominus Iesus was also published precisely to cut off these drifts. The document recalls that interreligious dialogue forms part of the evangelizing mission, but "does not replace" the missio ad gentes. And it warns against the relativism that deforms the definitive character of the revelation of Jesus Christ, the singularity of Christian faith, and the salvific uniqueness of Christ and the Church. More still: it affirms that men cannot enter into communion with God except through Christ and under the action of the Spirit. This affirmation alone suffices to measure the carelessness of the tweet. Because when the magisterium speaks of communion in the strong sense, it vindicates it to Christ, to the Church, and to the economy of salvation, not to an interreligious atmosphere of shared cordiality.
It will be said that this is pastoral language, not a dogmatic definition. But precisely there lies the danger. The majority of the faithful do not read conciliar documents or declarations from the Congregation for the Doctrine of the Faith. They read headlines, phrases, tweets, and slogans. And if from official channels technically incorrect vocabulary is employed, the practical result is deformed catechesis. The average faithful ends up concluding that all religions are, at bottom, variants of the same experience of God; that the mission no longer consists in announcing Christ, but in accompanying diverse spiritualities; and that the Church should renounce doctrinal precision to be welcoming. That is not pastoral. That is intellectual disarmament.
There is yet another significant detail. The tweet places that supposed "communion" under the mantle of Our Lady of Africa and speaks of the maternal love of Lalla Meryem that gathers all as children. The image may sound poetic, but there too a serious ambiguity slips in. Mary occupies in Christianity a place inseparable from the Incarnation of the Word. She is Mother of God because the Son born of her is true God and true man. In Islam, meanwhile, Mary is venerated, yes, but within a radically diminished Christology, where Jesus is not the incarnate Word nor the crucified and risen Redeemer. Invoking Mary as a common mantle without recalling the Christological truth that defines her is another way of using Catholic symbols for vaguely reconciling purposes, but doctrinally deactivated. Nostra aetate recognizes that Muslims honor Mary, but in the same passage reminds that they do not recognize Jesus as God. That precision is not secondary. It is the central question.
The Church does not need hostility toward Muslims. It needs exactness. It does not need verbal aggression. It needs conceptual clarity. No one disputes that Christians and Muslims can live together, collaborate for the common good, reject violence, and defend human dignity. The Council explicitly recommends it. What cannot be done is call "communion" what, according to Catholic doctrine itself, is at most coexistence, dialogue, cooperation, or a relationship of respect. Changing the name of things does not improve reality. It only makes it more confusing.
The underlying question is more serious than it appears. When ecclesiastical language ceases to be precise, faith becomes blurred. And when faith becomes blurred, the mission is paralyzed. If communion no longer requires the same faith, the same baptism, and the same incorporation into Christ, then there are no longer reasons to evangelize. It will suffice to celebrate differences, praise ethical convergences, and produce well-intentioned texts. But that is not Catholic logic. The Church exists to announce Jesus Christ, not to dissolve him in a universal spirituality of diplomatic tone. Lumen gentium opens precisely by affirming that Christ is the light of the peoples and that the Church desires to announce the Gospel to every creature. And the Catechism insists that the missionary effort begins with the proclamation of the Gospel to peoples who do not yet believe in Christ. If that still holds true, then one should not speak as if communion were already built where what is essential is still lacking.
In sum, the tweet does not scandalize by excess of courtesy, but by defect of theology. With a single misused word, it blurs the difference between human relationship and supernatural communion, between respect and unity of faith, between dialogue and ecclesial membership. And when a pontifical account normalizes that confusion, it is not building religious peace, but weakening the Catholic understanding of those who read it. There are terms that a journalist can use lightly. A pope cannot. And "communion," certainly, is one of them.
