The Truth About Religion: One True Faith?

The concept of religious exclusivism, or exclusivity, asserts that only one religion or belief system is true. This is in contrast to religious pluralism, which holds that multiple religions can be true. Many religions, including Christianity, Islam, and some sects of Buddhism, claim to be the one true faith or the one true church, often to the exclusion of other faiths. This belief has often led to conflict and violence, as adherents of these religions become convinced that they are defending or spreading the truth. However, it is important to note that not all religions make exclusive truth claims, and some, like Hinduism, even claim that all religions are true in their own way.

The Catholic Church claims to be the one true church

Religious exclusivism is the doctrine or belief that only one religion or belief system is true. Many religions claim to be the one true faith, and the two largest Christian branches, the Catholic Church and the Eastern Orthodox Church, are among them.

The Catholic Church teaches that Christ founded only "one true Church", and that this church is the Catholic Church, with the Bishop of Rome (the Pope) as its supreme, infallible head. The Catholic Church is considered to be the sole Church of Christ, defined as "one, holy, catholic, and apostolic" in the Nicene Creed. This creed was originally formulated by the Council of Nicea in AD 325. The church teaches that only the Catholic Church was founded by Jesus Christ, who appointed the Twelve Apostles to continue his work as the Church's earliest bishops. This belief holds that the Church "is the continuing presence of Jesus on earth", and that all duly-consecrated bishops have a lineal succession from the apostles.

The Catholic Church's claim to be the one true church is further supported by its interpretation of the Four Marks of the Church mentioned in the Nicene Creed:

• "One" refers to the Catholic Church's claim to be the sole Church of Christ.
• "Holy" refers to the belief that the Catholic Church is the "universal sacrament of salvation for the human race" and the "only true religion".
• "Catholic" refers to the Church's universality, meaning it is not limited by geographical or chronological boundaries and can speak to all situations.
• "Apostolic" refers to the belief that the Catholic Church is the continuing presence of Jesus on earth, with the Pope as the successor to the apostle Simon Peter.

In addition to these four marks, the Catholic Church identifies twelve traits of authority that further support its claim to be the one true church. These twelve traits include being rooted in history, objective, universal, intellectually challenging yet accessible, both invisible and visible, and both human and divine.

The Catholic Church's claim to be the one true church is a central tenet of its faith and is based on its interpretation of scripture, tradition, and authority.

The Eastern Orthodox Church also claims to be the one true church

The Eastern Orthodox Church, officially the Orthodox Catholic Church, is the second-largest Christian church, with approximately 230 million baptised members. It operates as a communion of autocephalous churches, each governed by its bishops via local synods. The church has no central doctrinal or governmental authority analogous to the head of the Catholic Church (the pope). Nevertheless, the Ecumenical Patriarch of Constantinople is recognised by them as primus inter pares ("first among equals"), a title formerly given to the patriarch of Rome. As one of the oldest surviving religious institutions in the world, the Eastern Orthodox Church has played an especially prominent role in the history and culture of Eastern and Southeastern Europe.

Eastern Orthodox theology is based on the Scriptures and holy tradition, which incorporates the dogmatic decrees of the seven ecumenical councils, and the teaching of the Church Fathers. The church teaches that it is the one, holy, catholic and apostolic church established by Jesus Christ in his Great Commission, and that its bishops are the successors of Christ's apostles. It maintains that it practises the original Christian faith, as passed down by holy tradition.

The Eastern Orthodox Church considers itself to be both orthodox and catholic. The doctrine of the Catholicity of the Church, as derived from the Nicene Creed, is essential to Eastern Orthodox ecclesiology. The term Catholicity of the Church (Greek Καθολικότης τῆς Ἐκκλησίας) is used in its original sense, as a designation for the universality of the Christian Church, centred around Christ. Therefore, the Eastern Orthodox notion of catholicity is not centred around any singular see, unlike the Catholic Church which has one earthly centre.

The Eastern Orthodox Church is defined as the Eastern Christians which recognise the seven ecumenical councils and usually are in communion with the Ecumenical Patriarchate, the Patriarchate of Alexandria, the Patriarchate of Antioch, and the Patriarchate of Jerusalem. The Eastern Orthodox churches "are defined positively by their adherence to the dogmatic definitions of the seven [ecumenical] councils, by the strong sense of not being a sect or a denomination but simply continuing the Christian church, and, despite their varied origins, by adherence to the Byzantine rite". Those churches are negatively defined by their rejection of papal immediate and universal supremacy.

The Eastern Orthodox Church claims that it is today the continuation and preservation of that same early church. A number of other Christian churches also make a similar claim: the Roman Catholic Church, the Anglican Communion, the Assyrian Church, and the Oriental Orthodox. In the Eastern Orthodox view, the Assyrians and Orientals left the Orthodox Church in the years following the Third Ecumenical Council of Ephesus (431) and the Fourth Ecumenical Council of Chalcedon (451), respectively, in their refusal to accept those councils' Christological definitions. Similarly, the churches in Rome and Constantinople separated in an event known as the East–West Schism, traditionally dated to the year 1054, although it was more a gradual process than a sudden break.

The Eastern Orthodox Church considers Jesus Christ to be the head of the Church and the Church to be his body. It is believed that Church authority and the grace of God is directly passed down to Orthodox bishops and other clergy through the laying on of hands—a practice started by the New Testament apostles—and that this unbroken historical link is an essential element of the true church. The Eastern Orthodox Church asserts that apostolic succession requires apostolic faith, and bishops without apostolic faith, who are in heresy, forfeit their claim to apostolic succession.

The Eastern Orthodox Church, in understanding itself to be the Body of Christ, and similarly in understanding the Christian life to lead to the unification in Christ of all members of his body, views the church as embracing all Christ's members, those now living on earth, and also all those through the ages who have passed on to the heavenly life. "In general," Eastern Orthodox Christianity sees the Church "as a purely mystical body, the understanding of which cannot be attained through the development of a rational or natural theology."

Many mainstream Protestants hold a different view

This view is based on the Protestant principle of sola scriptura, which holds that the Bible is the sole infallible source of authority for Christian faith and practice. As such, Protestants reject the Catholic Church's claim of papal infallibility and its assertion that it is the one true church founded by Christ.

However, it is worth noting that there is no overarching authority within Protestantism, and denominations differ in their interpretations of the Bible. While some Protestant denominations may claim to be the one true church, this is not a consistent doctrine across Protestantism.

The dangers of the only-one-true-religion thesis

The belief that only one religion is true, known as religious exclusivism, is a dangerous thesis that has the potential to cause harm even if it is false. This is because people may still act on it, believing it to be true. One of the most significant dangers of this thesis is that it has been used to justify violence and oppression in conflicts between nations or peoples of different faiths. Religion has been exploited to validate opposing causes, and the conviction that one possesses the Truth can be used to justify extreme actions. Young men have been motivated by their religion to kill and be killed for their faith, and chaplains have assured them that their cause is righteous and just. As a result, countless lives have been lost, and civilians have been slaughtered, oppressed, discriminated against, or exploited in the name of God.

Another negative consequence of the "only-one-true-religion" thesis is that it creates an unequal power dynamic in inter-faith dialogue. Even if individuals from different faiths are personally courteous and friendly, the belief that only one religion is true means that each person believes they are speaking from a position of religious superiority. This dynamic can hinder meaningful and respectful dialogue between individuals of different faiths.

Furthermore, the "only-one-true-religion" thesis can lead to a sense of spiritual advantage or disadvantage based on one's birth. For example, a person born into a Catholic family in Ireland is likely to be a Catholic Christian, while someone born into a Muslim family in Pakistan is likely to be a Muslim. This idea of spiritual advantage or disadvantage based on birth can conflict with the belief in a God who loves all human children equally.

The belief that only one religion is true can also foster an "us versus them" mentality, leading to discrimination, intolerance, and religious persecution. It can also hinder spiritual growth and exploration, as individuals may feel confined to a single religious path without the freedom to explore other faiths or incorporate aspects of multiple traditions into their spiritual practice.

Finally, the "only-one-true-religion" thesis can lead to a sense of religious superiority and close-mindedness, making individuals believe that their way is the only right way. This can result in a lack of respect for other faiths and a refusal to acknowledge the validity of other religious traditions.

The one true religion depends on where you are born

The idea that there is only one true religion is a belief held by many people of different faiths. This is known as religious exclusivism or exclusivity, the doctrine that only one religion or belief system is true. This is in contrast to religious pluralism, the idea that multiple religions are true.

However, the religion that people follow is often heavily influenced by where they are born. For example, someone born into a Catholic family in Ireland is very likely to be a Catholic Christian, while someone born into a Muslim family in Pakistan is very likely to be a Muslim. While individual conversions do occur, they are statistically insignificant compared to the massive transmission of each faith from generation to generation within the same tradition.

This raises the question: if there is only one true religion, does that mean that there is a spiritual advantage to being born into that religion, and a corresponding disadvantage to being born into another faith? This idea can be troubling, as it implies that those who follow other religions are in error and do not have an equal opportunity to attain salvation.

Furthermore, the belief in one true religion has often been exploited to justify conflicts and violence against those of different faiths. Young men have been motivated by their religion to kill and be killed for their faith, with chaplains assuring them that they are fighting for a righteous and just cause.

In inter-faith dialogue, the belief in one true religion can also create an imbalance, as each person believes that they are speaking from a position of religious superiority, even if they are being courteous and friendly.

While it is comforting to believe that one's own religion is the only true path, it is important to recognize that people of other faiths hold similar exclusive claims about their own religions. As such, the notion that one's religion is the only true one based solely on the circumstance of birth may not be a compelling argument.

Instead, it may be more realistic and believable to adopt a pluralistic outlook, recognizing that different religions have similar ideas of love and the goal of benefiting humanity, even if their specific doctrines differ.
