Is the Iglesia ni Cristo a “Cult”? (An Apologetic Examination — Doctrine, History & How to Judge a Religious Group)

Claiming that INC 1914 is the Church of Christ is a big lie.

Is the Iglesia ni Cristo (INC) a cult? This evidence-based article examines doctrinal criteria, Scripture, the Fathers, church history, theologians, and the Catechism to explain how Christians judge movements and why many theologians classify INC as a non-orthodox sect.

 

First of all, let me tell you what do I mean for Cult.

Christian Theological Definition of Cult:
“A religious group that claims to be Christian but denies one or more essential doctrines of historic Christianity (such as the Trinity, the divinity of Christ, or salvation by grace).” — Walter Martin, “The Kingdom of the Cults”

 

 


Introduction — why this question matters

“Cult” is a loaded word. People often use it as an insult, but in theology and religious studies it has specific criteria: departure from historic Christian doctrine, a novel founder or revelation, claims of exclusive salvation, and organizational control that replaces apostolic authority. This article explains how Christians should evaluate any group (including the Iglesia ni Cristo / INC), presents the relevant biblical and historical standards, compares INC teaching with orthodox Christianity, and offers a pastoral conclusion—respectful, careful, and evidence-based.


1 — How to define a “cult”: theological & sociological criteria

Before judging, we need clear criteria. Below are commonly used markers from apologetics, theology, and sociology.

Type of criterionWhat to look for
DoctrinalDenies core Christian doctrines (Trinity, deity of Christ, substitutionary atonement).
AuthorityNew founder/prophet who claims exclusive authority or new revelation superseding the apostles.
SoteriologyClaims that only membership in the movement guarantees salvation.
EcclesiologyRejects apostolic succession / catholicity and posits a separate “true church.”
Practice/ControlAuthoritarian governance, discouraging outside critique or exit.
Historical continuityLacks continuity with the historic, apostolic Church (1st–4th centuries).

Important caveat: A group may have one or more cultic features yet be harmless socially; conversely social harm may exist without doctrinal deviation. Our focus is primarily theological (orthodoxy) and ecclesiological (claims about being the sole true church).

 

2 — Biblical benchmark: what is essential Christian doctrine?

Historic Christian orthodoxy is summarized in Scripture and in ecumenical creeds. These items are the measuring stick.

Biblical / Creedal benchmarkWhy it matters
Trinity (One God in three persons) — e.g., Matthew 28:19; Nicene CreedDefines God’s revealed nature and Christian worship.
Christ’s full deity & humanity — John 1:1,14; Chalcedonian definitionsNecessary for atonement and salvation (Hebrews; Romans).
Salvation by grace through Christ — Ephesians 2:8–9; Acts 4:12Establishes the means of reconciliation with God.
Apostolic authority / continuity — Acts 2; 1 Timothy 3:15The Church is rooted in apostolic witness and teaching.
Scripture as normative (canon + apostolic Tradition) — 2 Peter 1:20–21; 1 Tim 3:15Guides interpretation and guards error.

If a religious body repudiates one or more of these essentials, historic Christian theologians have labeled it heterodox — and often “cultic” when combined with exclusivist claims.


3 — What INC teaches (doctrinal summary) — reported teachings, summarized respectfully

Below is a concise, neutral summary of INC doctrinal positions as presented in INC literature and commonly noted by scholars and Christian apologists. (The aim here is description, not polemics.)

  • Founder / origin: Iglesia ni Cristo (INC) was organized by Felix Y. Manalo in the Philippines (registered 1914).

  • Christology: INC teaches that Jesus Christ is a human being with divine authority (not God the Son in the Trinitarian sense). They deny the doctrine of the Trinity and the full ontological divinity of Christ in the classical Christian sense.

  • Trinity: INC rejects the doctrine of the Trinity — affirming strict monotheism but not Trinitarian formulation.

  • Ecclesiology / salvation: INC teaches that it is the one true church established by Christ in the last days and that salvation is mediated through INC membership and its rites.

  • Authority: Felix Manalo is regarded by INC as God’s messenger who restored the true church. Leadership is centralized in the INC administration.

  • Scripture: INC accepts the Bible but interprets it through the lens of its own doctrines and authoritative leadership.

Note: Descriptions above are summary-level; for exact INC statements consult their official publications and position papers.


4 — How does INC compare with historic Christian orthodoxy?

TopicHistoric Christian OrthodoxyINC teaching (summary)Result
TrinityOne God in three persons (Father, Son, Holy Spirit)Denies Trinity; Christ is not God the Son in Trinitarian senseMajor doctrinal divergence
Christ’s natureJesus is fully God and fully man (hypostatic union)Jesus is a man given divine authority; not ontologically GodMajor divergence
Atonement & salvationChrist’s atoning death & resurrection save sinners by grace (universal offer)Emphasizes church membership and INC administration as means to salvationSignificant divergence
Authority / foundingChurch founded by Christ, apostolic succession (historic continuity)Founded by Felix Manalo (1914); claims restored “one true church”No apostolic continuity
ExclusivityCatholic/Orthodox/Protestant vary on particulars but accept catholicity of the ChurchTeaches exclusivity: INC as the true church and path to salvationSectarian

Interpretation: The INC departs from the core of historic Christian doctrine (especially Trinitarian Christology and ecclesiology). From a classical Christian theological viewpoint, those are essential matters. That is why many Christian theologians and apologetic works classify INC as a non-Trinitarian sect and, in theological language, as “cultic” in belief (i.e., heterodox with exclusivist claims).

 


5 — Historical context & development (timeline)

Year / PeriodEvent
1914Felix Y. Manalo registers Iglesia ni Cristo as a religious organization in the Philippines (INC’s founding date).
1920s–1930sINC expands in the Philippines; builds organizational structures, central administration.
Post-WWIIRapid growth domestically and formation of missionary activities overseas.
Late 20th c.–21st c.Political influence in the Philippines, large gatherings, continued claim of exclusivity.

 

6 — What did the early Church and Fathers teach about heresy, schism, and “false teachers”?

The patristic witness provides the criteria the Church has historically used to identify heresy:

  • Irenaeus (2nd c.) emphasized apostolic succession and the rule of faith preserved by the churches as a safeguard against novel doctrines (see Against Heresies).

  • Tertullian and Origen argued for fidelity to apostolic teaching and warned against private reinterpretations.

  • Councils (e.g., Nicaea 325) defined core doctrines (Trinity, Christ’s divinity) and condemned divergent teachings (Arianism).

Application: When a later movement denies what ecumenical councils and the apostolic consensus taught about God and Christ, the Fathers would label it heretical. If that movement asserts itself as the only true church and claims new revelation or a restorative founder, it fits patterns of past sectarian movements the Fathers contested.

 

 

7 — Why many theologians/apologists call INC “cultic” (summary of reasoning)

Based on the criteria earlier, the common reasons are:

  1. Doctrinal departure from core doctrines (Trinity, Christ’s divinity).

  2. Exclusive soteriology: teaching that salvation is bound to INC membership and rites rather than to Christ alone in the universal offer.

  3. New authoritative founder: Felix Manalo presented as God’s messenger who restored the true church — a pattern similar to other restoration movements.

  4. Ecclesial claims: INC claims to be the one true Church restored in the modern era (a classic hallmark of sectarian movements).

  5. Sociological dynamics: strong centralized leadership and clear boundary maintenance (though levels of social control vary and not all INC communities show extreme authoritarian behavior).

Because of those features, INC is classed by many orthodox theologians and Christian apologists as a non-Trinitarian sect or a movement with cultic characteristics in belief. That is a theological classification, not necessarily a moral judgment of individual members.


8 — Pastoral considerations & how to engage respectfully

Labeling a group “cult” is theological, but pastoral charity is essential.

  • Respect people, critique doctrine. Members are beloved persons; we correct beliefs, not people. (Ephesians 4:15; 1 Peter 3:15).

  • Focus on evangelization through witness. Live and explain the Gospel clearly: Christ’s divinity, atoning work, and the free offer of salvation by grace.

  • Encourage study of history and creeds. The ecumenical creeds and patristic writings show what historic Christianity has always confessed.

  • Warn about exclusivist claims. Teach that the Bible warns against movements that add conditions to Christ’s salvation (Galatians; 2 Peter).

  • Pray and dialog. Dialogue can uncover sincere motives, cultural contexts, and ways to witness truth in love.


9 — Recommended primary & secondary sources

Scripture (key passages to study):

  • Ephesians 4:4–6 — “One body… one Lord, one faith, one baptism.”

  • John 1:1–14; Colossians 1:15–20; Hebrews 1 — Christ’s divinity and preeminence.

  • Acts 2; Matthew 16 — apostolic foundation and authority.

Patristic / classical references:

  • Irenaeus, Against Heresies — apostolic succession and rule of faith.

  • Athanasius, On the Incarnation — defense of Christ’s divinity.

  • Council of Nicaea (325) — Nicene Creed.

Modern apologetics & reference works:

  • Walter Martin, The Kingdom of the Cults — survey of modern movements and criteria.

  • Henry Bettenson, Documents of the Christian Church — primary texts and creeds.

  • Catechism of the Catholic Church (relevant paragraphs on the Trinity, Christology, salvation, and ecumenism).

  • Scholarly articles on INC’s doctrines (theological reviews and religious studies analyses).


10 — Short FAQ

Q: Is it sinful to be in INC?
A: Individual conscience and culpability are matters for God. Theologically, the Church teaches that error about essential truths harms one’s standing in the truth; pastoral care and evangelization should be applied with charity.

Q: Are all INC members cult victims?
A: Not necessarily. Many joined out of sincere conviction, family ties, or cultural reasons. “Cultic” as a theological term describes beliefs and ecclesial claims; social dynamics vary.

Q: Can INC doctrines be corrected?
A: Yes — as with historic heresies, patient teaching, scriptural exegesis, and appeal to the creeds and Fathers have remedied error in the past.


Conclusion — a measured apologetic summary

  • Definition matters. “Cult” should be used as a precise theological term — not as a slur.

  • Measured verdict: By classical Christian standards (Trinity, Christology, apostolic continuity, and soteriology), Iglesia ni Cristo departs significantly from historic, orthodox Christianity and therefore is theologically classified by many scholars and apologists as a non-Trinitarian sect with cult-like doctrinal characteristics.

  • But pastoral charity matters more than labels. We should respond with truth, patience, and love: explain the Gospel, point to Scripture and the Fathers, and pray for conversion of hearts.
