When Prefect Joseph Ratzinger published “Dominus Jesus”, he shook religious relativism and (false) ecumenism. On August 6, 2000, the Church upheld its Catholic identity without undermining interreligious dialogue.

On August 6, 2000, Joseph Ratzinger disrupted many people’s peace of mind.

Exactly twenty-five years ago, the Congregation for the Doctrine of the Faith, under the skilled leadership of the future Benedict XVI, released the “Dominus Iesus“, sparking fierce backlash.

Controversy erupted—despite the absence of social media: today, the fallout would likely have been devastating.

 

Ratzinger and Religious Relativism

Card. Ratzinger had the courage to firmly reaffirm what the Church has always believed: that Jesus Christ is the sole Saviour of humanity, and that the Catholic Church fully embodies the Church He founded.

This was no doctrinal innovation. There was nothing “new” in Dominus Iesus for those familiar with the Church’s Magisterium.

But the very need to restate Christ’s salvific uniqueness and the indispensable role of the Church revealed just how deeply the theological and cultural climate had been permeated by a relativist-pluralist mindset, where every religion was seen as equally valid.

It must be said that at the time—similarly to what has occurred under Pope Francis—some actions by then Pope John Paul II gave the impression that the Catholic Church was conceding to relativism.

Notable examples include respectful and reciprocal meetings with leaders of other faiths, the famous 1999 Koran kiss, and above all, the 1986 interreligious gathering in Assisi.

It was likely this context that prompted the Congregation for the Doctrine of the Faith (with John Paul II’s approval!) to issue a radical clarification—on ecumenism as well.

In that context, the declaration was a cold shower, a wake-up call, a challenge. So too was the Summary released a few months later by the former Holy Office, both explicitly approved by Saint John Paul II.

 

“Dominus Iesus”: Christ Alone and the Catholic Church Alone

The heart of the document was simple yet explosive: Jesus Christ is the sole mediator between God and humanity, and salvation cannot occur apart from Him.

But the real target of the declaration was the relativist premise that no religion can claim the full truth, and that all religions, at best, share partial insights into divine truth.

As Dominus Iesus described it: «a relativistic attitude toward truth, according to which what is true for some would not be true for others».

Thus, it reads: «There exists a single Church of Christ, which subsists in the Catholic Church, governed by the Successor of Peter and by the Bishops in communion with him», which «is necessary for salvation», because Christ—the mediator and the way to salvation—«he is present to us in his body which is the Church».

 

The World’s Reaction to “Dominus Iesus”

These statements had an incendiary effect on public opinion at the time—especially in the media—and on the world in general.

Countless ecumenical representatives tore their robes, and for months, a flood of words, statements, and disavowals followed. But nothing was retracted.

One can only imagine what might have happened in today’s social media era: a schism might have been the least of it.

 

The Church and the Value of Other Religions

Yet read today, Dominus Iesus carefully preserved the value of interreligious dialogue, repeatedly stressing that other religions may contain «elements of truth and goodness», and that there is «the real possibility of salvation in Christ for all», even those not formally members of the Catholic Church.

This is because «the salvation of Christ is accessible by virtue of a grace while having a mysterious relationship to the Church, does not make them formally part of the Church, but enlightens them in a way which is accommodated to their spiritual and material situation».

God grants this grace «through ways known to Him», but, the Congregation stressed, « 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».

Thus, other religions were not considered autonomous or equivalent paths to salvation. The Declaration reaffirmed «the Catholic faith regarding the full and complete revelation of the salvific mystery of God is given in Jesus Christ».

Further, Protestant communities that «have not preserved the valid Episcopate and the genuine and integral substance of the Eucharistic mystery» cannot be called “Churches” in the proper sense, as they lack apostolic succession and an adequate sacramental understanding. However, it was also stated that baptized individuals in those communities share «a certain communion, albeit imperfect, with the Church».

With his characteristic delicacy, Ratzinger further acknowledged «the elements of religiosity that are part of the Spirit’s work in the hearts of people, in history, cultures, and religions», but did not refrain from adding that various religious traditions cannot «be attributed with divine origin and salvific efficacy, which are proper to Christian sacraments».

Indeed, some rites rooted in superstition or other errors «constitute an obstacle to salvation».

In conclusion, even amid the «sincere respect» with which the Church views «the world’s religions», the former Holy Office categorically rejected «that mentality of indifferentism characterized by a religious relativism, which leads to the belief that ‘one religion is as good as another».

Finally quoting the Fathers of the Second Vatican Council, it reiterated that «this one true religion continues to exist in the Catholic and Apostolic Church, to which the Lord Jesus entrusted the task of spreading it among all people», who are called to seek the truth, «especially regarding God and His Church, and, once known, to embrace and hold it».

 

True Ecumenism Begins with Catholic Identity

Everything that might appear harsh or uncomfortable in the eyes of the modern world was restated as an act of fidelity to the truth. This was Ratzinger’s true merit: he refused to be intimidated by outraged reactions or accusations of being “closed-minded” or “intolerant.”

With a theologian’s sobriety and a pastor’s firmness, he sought to prevent interreligious dialogue from becoming a cultural surrender—or worse, an abdication of revealed truth. Dialogue is possible and necessary, but not at the expense of truth.

The Church respects each person’s freedom and every genuine search for God. But it cannot remain silent about what it has received: the proclamation that in Jesus Christ dwells bodily all the fullness of divinity.

As noted, the media uproar following the release of Dominus Iesus was massive. Some spoke of a betrayal of the ecumenical journey, others feared a breakdown in interreligious relations.

Yet in hindsight, it is clear that the text was necessary. Not to create needless divisions, but to prevent harmful and damaging confusion.

There can be no true ecumenism, no interreligious dialogue, unless it starts from truth. Ironically, this has been reiterated by Pope Francis himself, who has also faced accusations of relativism for some of his conciliatory gestures and controversial interviews.

And yet, Francis once powerfully explained:

«A facile syncretism would ultimately be a totalitarian gesture on the part of those who would ignore greater values of which they are not the masters. True openness involves remaining steadfast in one’s deepest convictions, clear and joyful in one’s own identity, while at the same time being “open to understanding those of the other party” and “knowing that dialogue can enrich each side”. What is not helpful is a diplomatic openness which says “yes” to everything in order to avoid problems, for this would be a way of deceiving others and denying them the good which we have been given to share generously with others. Evangelization and interreligious dialogue, far from being opposed, mutually support and nourish one another» (Apostolic Exhortation “Evangelii Gaudium“)

 

The Church of the future needs this clarity.

The prophetic voice of Ratzinger in Dominus Iesus remains a beacon, an act of love for the truth of the Catholic faith, which is universal precisely because it does not compromise itself or bend to the relativist trends of the world.
