On August 6, 2000, the Congregation for the Doctrine of the Faith (CDF), published the Declaration Dominus Iesus: On the Unicity and Salvific Universality of Jesus Christ and the Church (DI). Under the leadership of the eminent theologian Cardinal Joseph Ratzinger (later Pope Benedict XVI), the CDF hoped to address some disturbing trends in Roman Catholic theology and clarify the Church’s teaching against them.
Although DI addresses a number of issues, I will focus on what it teaches concerning non-Christian religions vis-à-vis the uniqueness and universality of the salvific mystery of Jesus Christ. For it is precisely on this question that much confusion had arisen due to liberal appropriations and interpretations of previous conciliar documents.
The great documents promulgated by the Second Vatican Council such as Lumen Gentium, Nostra Aetate, and Gaudium et Spes had spoken of the presence of spiritual truth in other religions and had encouraged religious dialogue. However, this had led some theologians to push beyond the clear boundaries indicated in these documents, leading to the relativising of the Christian Faith’s exclusive claims about Christ and salvation.
While DI does not specifically mention the names of the theologians in question, anyone familiar with the trends in Roman Catholic theology in the 1980s and 90s would be able to identify them.
In 1985, the Catholic theologian Paul F. Knitter published No Other Name? in which he criticised the exclusive claims of Christianity and presented a ‘pluralistic theology of religion’. Adopting a theocentric instead of a christocentric approach, Knitter could speak of non-Christian religions as valid paths to God and mediations of salvation.
In his later work, Knitter expressed dissatisfaction with the theocentric focus because it excludes non-theistic religions such as Buddhism. Consequently, he shifted his emphasis from theocentrism to soteriocentrism, focusing on the experiences of salvation in different religions.
However, it was the work of Fr Jacques Dupuis SJ entitled Toward Christian Theology of Religious Pluralism (1997), which came under review by the CDF, that led to the issuance of DI. In an attempt to present other religions as ‘positive ways of salvation’ while at the same time maintaining Christian particularity, Dupuis had, in the view of the CDF, undermined the uniqueness of Christ.
On January 19, 2001, CDF issued a Notification on Dupuis’ book which states that the members of the Congregation
… found that his book contained notable ambiguities and difficulties on important doctrinal points, which could lead a reader to erroneous or harmful opinions. These points concerned the interpretation of the sole and universal salvific mediation of Christ, the unicity and completeness of Christ’s revelation, the universal salvific action of the Holy Spirit, the orientation of all people to the Church, and the value and significance of the salvific function of other religions.
In addressing the relativising of Christ and Christian truth, DI affirms the definitive and complete character of the revelation of Jesus Christ.
DI was variously received by Catholic theologians. Conservative theologians praised it, even as it was met with the ire of liberal theologians who regarded it as a regression, bringing Catholicism back to a straitjacket exclusivism.
Some took issue with the tone of the document. For example, The Tablet, in an editorial on 9th September 2000 concluded: ‘What a pity that it sounds notes of triumphalism that the sympathetic style and way of acting of Pope John XXIII, newly beatified, seem to have dispelled for good.’
Cardinal Konig, formerly of Vienna, suggested that the document ‘could perhaps have been expressed more politely and could have reflected a greater eagerness for dialogue.’
Perhaps the most scathing criticism of DI came from the pen of the liberation theologian Leonardo Boff, who took issue because the document neglected the law of love and the poor – among other things. Boff writes:
Cardinal Ratzinger is not teaching the essence of Christianity. Without the essential, none of the arguments of the document can be sustained. Among others, two items are most serious: he leaves aside the centrality of the law of love and he has no place for the decisive importance of the poor.
In this article, I examine DI’s salient theological emphases and teachings and show that they are consistent with Roman Catholic theology in general, and its theology of religion in particular.
JESUS CHRIST: UNIQUE AND UNIVERSAL SAVIOUR
As the title of the document clearly indicates, the heart of DI is the affirmation that Jesus Christ is the sole and universal mediator and Saviour of humankind. As we have seen, this emphasis is made against the backdrop of religious pluralism and relativism which is present even in the Church and which threatens the integrity of the Christian faith.
DI clearly presents the dangers and challenges that the Church faces thus:
The Church’s constant missionary proclamation is endangered today by relativistic theories which seek to justify religious pluralism, not only de facto but also de jure (or in principle). As a consequence, it is held that certain truths have been superseded; for example, the definitive and complete character of the revelation of Jesus Christ, the Christian faith as compared with that of belief in other religions … (DI, 4).
Religious pluralism democratises religious truth, putting the revelation of God in Jesus at par with the truth-claims of other religions. Christ becomes just one among the many manifestations of the divine.
In confronting this problem of religious pluralism and theological relativism, DI clearly and categorically emphasises the fullness of the revelation of Jesus Christ in a paragraph saturated with Scriptural quotations.
As a remedy for this relativistic mentality, which is becoming ever more common, it is necessary above all to reassert the definitive and complete character of the revelation of Jesus Christ. In fact, it must be firmly believed that, in the mystery of Jesus Christ, the Incarnate Son of God, who is ‘the way, the truth, and the life’ (Jn 14:6), the full revelation of divine truth is given: ‘No one knows the Son except the Father, and no one the Father except the Son and anyone to whom the Son wishes to reveal him’ (Mt 11:27); ‘No one has ever seen God; God the only Son, who is in the bosom of the Father has revealed him’ (Jn 1:18); ‘For in Christ the whole fullness of divinity in bodily form’ (Col 2:9-10) (DI, 5).
DI therefore refutes the idea that other religions can supplement the truths that are revealed by Christ as if Christianity were merely one part of a larger religious whole. By asserting the complete character of the revelation of Jesus Christ, DI implies that insofar as truths can be found in other religions, they are at best partial and fragmentary.
This is consistent with the view of the Patristic writers such as Justin Martyr.
DI is also very quick to emphasise the soteriological implications of the absolute authority of Christ, the eternal Son of God incarnate.
It must be firmly believed as a truth of the Catholic faith that the universal salvific will of the One and Triune God is offered and accomplished once for all in the mystery of the incarnation, death, and resurrection of the Son of God (DI, 14).
The CDF recognises that ‘theology today, in its reflection on the existence of other religious experiences and on their meaning in God’s salvific plan, is invited to explore if and in what way historical figures and positive elements of these religions may fall within the divine plan of salvation’ (DI, 14).
However, it states that theological research in this area must be done ‘under the guidance of the Church’s Magisterium.’ Furthermore it categorically asserts that ‘those solutions that propose a salvific action of God beyond the unique mediation of Christ would be contrary to Christian and Catholic faith’ (DI, 14).
In its attempt to address relativism in the context of religiously plural society, DI specifically notes that the claim about the ‘absoluteness’ of the revelation of God in Christ has fallen out of favour.
Not infrequently it is proposed that theology should avoid the use of terms like ‘unicity’, ‘’universality’, and ‘absoluteness’, which give the impression of excessive emphasis on the significance and value of the salvific event of Jesus Christ in relation to other religion (DI, 15).
DI eschews this politically correct stance of some modern theologians and insists instead on being faithful to the revelation: ‘In reality, however, such language is simply being faithful to revelation, since it represents a development of the sources of faith themselves’ (DI, 15).
SALVIFIC VALUE OF NON-CHRISTIAN RELIGIONS
The high-Christology of DI serves as the foundation for what it has to say about the significance of non-Christian religions, especially the latter’s revelatory or salvific value.
DI emphasises the profound relationship between Christology and ecclesiology, between the incarnate Christ and the Church – his Body. It then makes the connection with the mystery of salvation of which the Church is a part.
The Lord Jesus, the only Saviour, did not establish a simple community of disciples, but constituted the Church as a salvific mystery: he himself is in the Church and the Church is in him (cf. Jn 15:1ff; Gal 3:28; Eph 4:15-16; Acts 9:5). Therefore, the fullness of Christ’s salvific mystery belongs also to the Church, inseparably united to her Lord (DI, 16).
Later in that same paragraph, DI reiterates this truth in a statement so clear that it cannot be misunderstood.
Therefore, in connection with the unicity and universality of the salvific mediation of Jesus, the unicity of the Church founded by him must be firmly believed as a truth of the Catholic faith. Just as there is one Christ, so there exists a single body of Christ, a single Bride of Christ: ‘a single Catholic and apostolic Church’ (DI, 16).
Having established the profound relationship between Christ and the Church in salvation, DI then draws out its implications, especially with regard to the salvific value of non-Christian religions. It argues that the Church is necessary for salvation.
… it must be firmly believed that the Church, a pilgrim now on earth, is necessary for salvation: the one Christ is the mediator and the way of salvation; he is present to us in the body which is the Church. He himself explicitly asserted the necessity of faith and baptism (cf. Mk 16:16; Jn 3:5) (DI, 20).
DI describes the Church as the ‘universal sacrament of salvation’, explaining that ‘since, united always in a mysterious way to the Saviour Jesus Christ, her Head, and subordinated to him, she has, in God’s plan, an indispensable relationship with the salvation of every human being’ (DI, 20).
Theologians with a liberal inclination have criticised this teaching as a regression into a rigid, constrictive form of fundamentalism and exclusivism. They alleged that this is a radical departure from the more inclusive stance presented in earlier official documents of the Church.
This criticism, however, is misguided and unfounded.
The Catholic Church’s view that ‘there is no salvation outside the Church’ (extra Ecclesium nulla salus) is a longstanding doctrine whose pedigree can be traced to Cyprian of Carthage (d. 258). In On the Unity of the Church, Cyprian famously taught this truth with the assertion that ‘He can no longer have God for his Father, who has not the Church for his mother’ (6).
This teaching enjoyed Patristic consensus. It is variously articulated by Origen and Augustine and taught by the medieval theologians such as Thomas Aquinas (1225-1274).
It continues to be emphasised in the Magisterial documents of the Catholic Church such as the pronouncements of the Fourth Lateran Council (1215) and Pope Boniface VIII’s encyclical Unam Sanctum (1302). It is clearly articulated in Lumen Gentium (1964), a document of the Second Vatican Council:
Basing itself upon Sacred Scripture and Tradition, it teaches that the Church, now sojourning on earth as an exile, is necessary for salvation. Christ, present to us in His body, which is the Church, is the one Mediator and the unique way of salvation. In explicit terms he himself affirmed the necessity of faith and baptism and thereby affirmed also the necessity of the Church, for through baptism as through a door men enter the Church. Whosoever, therefore, knowing that the Catholic Church was made necessary by Christ, would refuse to enter or to remain in it, could not be saved (LG, 14).
Based on this understanding of the fundamental role that the Church, as the Body of the Saviour, plays in salvation, DI states:
… it is clear that it would be contrary to the faith to consider the Church as one way of salvation alongside those constituted by the other religions, seen as complimentary to the Church or substantially equivalent to her, even if these are said to be converging with the Church towards the eschatological kingdom of God (DI, 21).
DI makes it a point to emphasise that although God is at work in non-Christian religions, they cannot be regarded as having the same status as Christianity. It discusses the sacred texts, rituals and belief systems of these religions vis-à-vis Christianity.
According to DI, God has made himself known ‘not only to individuals, but also to entire peoples through their spiritual riches, of which their religions are the main and essential expressions’. Insofar as the sacred books of other religions contain ‘elements of goodness and grace’, they received them from ‘the mystery of Christ’ (DI, 8).
However, DI is quick to add that the other religions (and their sacred texts) contain ‘gaps, insufficiencies and errors’. Only the ‘canonical books of the Old and New Testaments’ which are ‘inspired by the Holy Spirit’, ‘firmly, faithfully, and without error, teach that truth which is God, for the sake of our salvation’ (DI, 8).
In the same way, DI acknowledges that ‘the religious traditions contain and offer religious elements which come from God, and which are part of what the Spirit brings about in human hearts and in the history of peoples, in cultures, and religions’ (DI, 21).
However, it immediately qualifies that ‘One cannot attribute to these … a divine origin or an ex opere operato salvific efficacy, which is proper to the Christian sacraments’ (DI, 21). It adds further that ‘it cannot be overlooked that other rituals, insofar as they depend on superstitions or other errors (cf. 1 Cor 10:20-21) constitute an obstacle to salvation’ (DI, 21).
DI makes the distinction between ‘theological faith’ and ‘belief’ – the reception of revealed truth in Christianity and the belief systems of other religions.
Theological faith refers to the ‘acceptance in grace of revealed truth’ that ‘makes it possible to penetrate the mystery in a way that allows us to understand it coherently’ (DI 7). Belief, on the other hand, ‘is that sum of experience and thought that constitutes the human treasury of wisdom and religious aspiration, which man in his search for truth has conceived and acted upon in his relationship to God and the Absolute’ (DI, 7).
DI therefore concludes:
If it is true that the followers of other religions can receive divine grace, it is also certain that objectively speaking they are in a gravely deficient situation in comparison with those who, in the Church, have the fullness of the means of salvation (DI, 21).
This does not contradict – as some have alleged – the statement in Nostra Aetate that ‘The Catholic Church rejects nothing that is true and holy in these religions’ (2). But it does emphasise that these religions cannot be seen as autonomous vehicles of salvation or different paths to God. They are at best preparations for the Gospel (praeparatio evangelica).
DI also stresses that the statement from Nostra Aetate must be understood in the context of the Church’s consistent teaching concerning the uniqueness of Christ.
MISSION AND DIALOGUE
Given DI’s high Christology and ecclesiology, together with its clear articulation of the salvific value of other religions, its statements on mission and dialogue should not come as a surprise. While it does recognise the value of dialogue, it clarifies that dialogue does not negate the necessity of mission and evangelisation, which is the Church’s basic work.
Indeed, God desires all men to be saved and come to the knowledge of the truth. Salvation is found in the truth. Those who obey the promptings of the Spirit of truth are already on the way to salvation, But the Church, to whom this truth has been entrusted, must go out to meet their desire, so as to bring them the truth. Because she believes in God’s universal plan of salvation, the Church must be missionary (DI, 22).
DI does not deny that God is at work in the world, drawing people to him. It does not deny the possibility of salvation for those ‘who through no fault of their own’ do not know Christ (i.e., the ‘invincibly ignorant’) (Cf. LG, 16). But it insists that it is the Church’s task to bring the truth to all.
Interfaith dialogue is important, but it must be understood as a part of the mission of the Church and not independent of it. ‘Inter-religious dialogue, therefore, as part of her evangelising mission, is just one of the actions of the Church in her mission ad gentes’ (DI, 22).
Liberal approaches to inter-faith dialogue often tend to democratise the truth. According to this view, different bits of the truth are found in different religions such that no one religion – including Christianity – possesses the whole truth. Dialogue then becomes an exercise of putting the religion puzzle together with each religion bringing the piece of the truth it possesses to the table.
DI rejects this egalitarian understanding of truth and its bearers. However, DI does speak of the equality, respect and freedom of the dialogue partners.
Equality, which is a presupposition of inter-religious dialogue, refers to the equal personal dignity of the parties in dialogue, not to doctrinal content, nor even less to the position of Jesus Christ – who is God himself made man – in relation to the founders of other religions. Indeed, the Church, guided by charity and respect for freedom, must be primarily committed to proclaiming to all people the truth definitively revealed by the Lord, and to announcing the necessity of conversion to Jesus Christ and adherence to the Church through Baptism and other sacraments, in order to participate fully in communion with God, the Father, Son and the Holy Spirit (DI, 22).
Inter-faith dialogue should not lead to the dilution of Christian distinctiveness. It certainly should not result in compromising the Gospel.
25 YEARS ON
Twenty-five years after its promulgation in 2000, DI remains relevant to the Church (both Catholic and Protestant) today. Its uncompromising emphasis on the uniqueness of Christ, the authority of the Gospel and the mission of the Church continue to challenge the Church to remain faithful in an age of relativism.
DI is also important for the Church as she navigates new challenges in the form of secularism, syncretism, and religious indifferentism. It serves as a theological anchor which ensures that the Gospel is not diluted or abandoned for the sake of accommodating pluralism.
Finally, DI teaches the Church that the most profound expression of love is to tell the truth about the Lord Jesus Christ, the incarnate Son of God, who died ‘for us and for our salvation’, as the Nicene Creed professes.
