What Do Christians Believe About Other Religions?

Q: What does the Bible say about mixing Christian faith with other beliefs?

Paul draws a sharp line in 2 Corinthians 6:15 — what concord hath Christ with Belial? or what part hath he that believeth with an infidel? 2 Corinthians 6:15 — suggesting incompatibility between Christian faith and other religious commitments. Most Christian traditions interpret this as a warning against syncretism.

TL;DR: This question is fundamentally Christian in scope. Christian views on other religions range widely — from strict exclusivism (salvation only through Christ) to inclusivist and pluralist positions. Scripture like 2 Corinthians 6:15 raises questions about the relationship between believers and non-believers 2 Corinthians 6:15, while 1 Corinthians 15:14 underscores the centrality of Christ's resurrection as the non-negotiable core of Christian faith 1 Corinthians 15:14. Philippians 1:18 shows even early Christians debated the boundaries of authentic proclamation Philippians 1:18. Theologians like Karl Barth, John Hick, and Clark Pinnock represent the spectrum of these ongoing debates.

Judaism

Not applicable. This question concerns specifically Christian theological positions on other religions and has no direct counterpart in Judaism.

Christianity

And what concord hath Christ with Belial? or what part hath he that believeth with an infidel? (2 Corinthians 6:15, KJV)

Christian views on other religions aren't monolithic — they've been debated for centuries and remain contested today. Broadly, three positions dominate contemporary theology: exclusivism, inclusivism, and pluralism.

Exclusivism

The exclusivist position holds that salvation is available only through explicit faith in Jesus Christ. This view draws heavily on the resurrection's centrality to Christian identity. Paul writes in 1 Corinthians 15:14 that if Christ be not risen, then is our preaching vain, and your faith is also vain 1 Corinthians 15:14, and in 15:17 that without the resurrection, believers remain yet in your sins 1 Corinthians 15:17. The implication is that the specific content of Christian faith — not just general religiosity — is what matters. Karl Barth (20th century) is the most famous exclusivist theologian, arguing that all religion, including Christianity as a human institution, stands under divine judgment, but that Christ alone is the revelation of God.

The sharp contrast Paul draws in 2 Corinthians 6:15 — what concord hath Christ with Belial? or what part hath he that believeth with an infidel? 2 Corinthians 6:15 — has historically been cited to support a firm boundary between Christian faith and other religious systems.

Inclusivism

Inclusivists, like Vatican II theologians and scholars such as Karl Rahner (d. 1984), argue that Christ is the unique savior but that his saving grace may operate through other religions without their adherents explicitly knowing it. Rahner's famous concept of the "anonymous Christian" reflects this. Philippians 1:18 offers a suggestive parallel: Paul rejoices that every way, whether in pretence, or in truth, Christ is preached Philippians 1:18, suggesting a certain openness to unexpected channels of divine activity.

Pluralism

Pluralists like John Hick (d. 2012) argue that multiple religions offer equally valid paths to the divine. This is a minority position among orthodox Christians and is rejected by most evangelical and Catholic authorities, who maintain Christ's uniqueness. The New Testament's emphasis on Christ as the singular "Rock" — that Rock was Christ (1 Corinthians 10:4) 1 Corinthians 10:4 — is frequently cited against pluralism.

Practical Attitudes

Most mainstream Christian denominations today encourage respectful dialogue with other faiths while maintaining their own truth claims. The Catholic Church's Nostra Aetate (1965) acknowledged truth and holiness in other religions. Evangelical bodies tend toward exclusivism while still affirming human dignity across traditions. There's genuine, unresolved disagreement here — don't let anyone tell you Christians all think alike on this.

Islam

Not applicable. This question concerns Christian theological positions on other religions and has no direct counterpart in Islamic doctrine as framed here.

Where they agree

Since only Christianity is in scope for this question, a cross-religion agreement section isn't applicable. Within Christianity, virtually all traditions agree that the resurrection of Christ is the non-negotiable center of Christian identity 1 Corinthians 15:14 1 Corinthians 15:17, and that this distinguishes Christian faith from other religious systems in some meaningful way — even if they disagree sharply on what that distinction implies for the salvation of non-Christians.

Where they disagree

Position	View on Other Religions	Key Proponents	Scriptural Anchor
Exclusivism	No salvation outside explicit Christian faith	Karl Barth, most evangelical denominations	1 Cor. 15:14 1 Corinthians 15:14; 2 Cor. 6:15 2 Corinthians 6:15
Inclusivism	Christ saves universally; other religions may mediate grace unknowingly	Karl Rahner, Vatican II Catholics	Phil. 1:18 Philippians 1:18
Pluralism	Multiple religions offer equally valid paths to God	John Hick, liberal Protestant theologians	Largely argued against scripture; minority view

Key takeaways

Christian views on other religions span three main positions: exclusivism, inclusivism, and pluralism — with exclusivism being the historically dominant view.
The resurrection of Christ (1 Cor. 15:14, 15:17) is the theological anchor that makes Christian faith distinct in the eyes of most Christians.
Paul's sharp contrast in 2 Corinthians 6:15 between believers and non-believers has historically supported firm boundaries between Christianity and other religions.
Scholars like Karl Barth, Karl Rahner, and John Hick represent genuinely different — and still debated — theological frameworks on this question.
This question is Christian-specific; Judaism and Islam are not in scope.

FAQs

Do Christians believe people of other religions can be saved?

It depends on the tradition. Exclusivists say no — salvation requires explicit faith in Christ, grounded in the resurrection's centrality 1 Corinthians 15:14. Inclusivists say Christ's saving work may reach beyond the visible church. Pluralists say yes, through their own paths — though this is a minority position among orthodox Christians.

What does the Bible say about mixing Christian faith with other beliefs?

Paul draws a sharp line in 2 Corinthians 6:15 — what concord hath Christ with Belial? or what part hath he that believeth with an infidel? 2 Corinthians 6:15 — suggesting incompatibility between Christian faith and other religious commitments. Most Christian traditions interpret this as a warning against syncretism.

Did early Christians debate the boundaries of authentic faith?

Yes. Philippians 1:18 shows Paul acknowledging that Christ was preached whether in pretence, or in truth and choosing to rejoice regardless Philippians 1:18, suggesting early Christians wrestled with questions of authenticity and boundaries from the very beginning.

Is the resurrection relevant to how Christians view other religions?

Very much so. 1 Corinthians 15:17 states that without the resurrection, believers are yet in your sins 1 Corinthians 15:17, making the resurrection the hinge on which Christian distinctiveness turns. If Christ truly rose, most Christians argue, that event is universally significant — which shapes how they assess other religious claims.

TL;DR: In the New Testament, the touchstone for assessing any message is Christ himself—especially his resurrection; without it, faith is empty 1 Corinthians 15:14. Christians also see value in Christ being proclaimed, even when motives are mixed, which tempers rivalry as they encounter competing claims Philippians 1:18. The bond between Christ and the church is called a “great mystery,” shaping Christian self-understanding in relation to the wider religious world Ephesians 5:32.

Judaism

Not applicable. Concerns a Christian-specific question about how Christians view other religions; no direct Jewish counterpart required by the prompt.

Christianity

And if Christ be not risen, then is our preaching vain, and your faith is also vain.

The New Testament frames evaluation of any message by its relation to Christ’s resurrection: if Christ is not risen, preaching and faith are vain, making the resurrection the decisive criterion when Christians weigh other claims 1 Corinthians 15:14.

Paul also reports rejoicing whenever Christ is preached—even if done from mixed or rival motives—indicating a posture that prizes the proclamation of Christ above party spirit, which influences how Christians face competing messages and communities Philippians 1:18.

Further, the church’s union with Christ is called “a great mystery,” reinforcing a distinctive self-understanding that guides Christian engagement with religious others from within a Christ–church paradigm Ephesians 5:32.

Islam

Not applicable. The question targets Christian belief and New Testament grounding; Islamic doctrine is not the focus here.

Where they agree

Within this Christian framing: (1) the resurrection functions as the non-negotiable core for judging truth-claims 1 Corinthians 15:14; (2) Christ being preached is a cause for joy even amid imperfect motives, moderating rivalry in public witness Philippians 1:18; and (3) the Christ–church union as a “great mystery” shapes the church’s distinct identity vis-à-vis the world Ephesians 5:32.

Where they disagree

Area of tension	How the text is used	Citation
Criterion for truth	Some readings emphasize the resurrection as the definitive test for any message about God or salvation.	1 Corinthians 15:14 1 Corinthians 15:14
Attitude toward rival proclaimers	Debate over how far Paul’s joy at Christ being preached extends when motives or affiliations differ.	Philippians 1:18 Philippians 1:18
Church’s boundary and identity	Discussion on how the “great mystery” of Christ and the church informs engagement with non-church communities.	Ephesians 5:32 Ephesians 5:32

Key takeaways

Christ’s resurrection is the central Christian criterion for evaluating truth-claims 1 Corinthians 15:14
Proclaiming Christ is prioritized over rivalry, even when motives are mixed Philippians 1:18
The Christ–church union as a “great mystery” shapes Christian self-understanding in public engagement Ephesians 5:32
These anchors guide many Christians as they consider and respond to other religions’ claims Philippians 1:18
Assessments revolve around Christ’s person and work rather than generic theism 1 Corinthians 15:14
