HERESY
Definition:
The Christian Meaning of “Heresy”
Heresy is a belief or teaching that contradicts the essential, core doctrines of the Christian faith as taught in Scripture and affirmed by the historic Church.
It is not:
a disagreement
a denominational difference
a matter of opinion
an interpretive variation
Heresy distorts the nature of God, the gospel, or the identity of Christ in ways that lead people away from saving truth.
DEFINITIONS
Biblical Meaning
The New Testament warns repeatedly against false teaching:
“False teachers… introducing destructive heresies.” — 2 Peter 2:1
“If anyone preaches a gospel contrary… let him be accursed.” — Galatians 1:8
Heresy is spiritually harmful, not merely incorrect
This truth shows that heresy is dangerous because it misleads hearts and distorts the gospel.
You can take Scripture’s warnings seriously as acts of divine protection.
WHAT QUALIFIES AS HERESY?
Heresy contradicts doctrines Christians across time and traditions consider essential.
1. The Nature of God
Denying the Trinity
Claiming multiple gods
Rejecting God’s sovereignty or holiness
2. The Identity of Jesus Christ
Denying Jesus is fully God
Denying Jesus is fully human
Denying the resurrection
3. The Gospel Itself
Salvation by works alone
Salvation apart from Christ
Adding to or subtracting from the gospel
4. The Authority of Scripture
Rejecting apostolic teaching
Replacing Scripture with new revelations
Key Idea
Heresy distorts truths necessary for salvation.
Reflection
Essential doctrines are the pillars of Christian faith. You can guard them with humility and conviction.
DISTINGUISHING HERESY FROM NON‑ESSENTIAL DIFFERENCES
Not heresy:
Church governance differences
Baptism methods
End‑times views
Worship styles
Spiritual gifts
Denominational traditions
These are important but not salvation issues.
Key Idea
Heresy strikes at the heart of the Christian faith.
Reflection
Unity requires distinguishing essentials from non‑essentials.
You can hold convictions firmly while showing charity in secondary matters.
HISTORICAL INSIGHT
The early Church confronted major heresies:
Arianism — denied Christ’s deity
Gnosticism — denied Christ’s humanity
Pelagianism — denied original sin and grace
Modalism — denied the Trinity
Docetism — claimed Jesus only “appeared” human
These controversies led to clearer doctrinal statements like the Nicene Creed.
Reflection
Heresy forced the Church to clarify truth. You can appreciate the creeds as gifts forged in theological struggle.
INFLUENTIAL CHRISTIAN THINKERS ON HERESY
Athanasius: “Heresy takes from Christ what is His.”
Augustine: Heresy is opinion contrary to Scripture.
Calvin: Heresy departs from the pure gospel.
C.S. Lewis: Christians may differ on many things, but a central core must be held.
Reflection
The Church’s greatest thinkers saw heresy as a threat to the gospel. You can learn from their clarity and courage.
WHY HERESY MATTERS
Heresy:
Distorts God’s character
Misrepresents the gospel
Prevents people from knowing the true Christ
Leads believers into deception
Divides the Church from truth
Truth saves. Error destroys.
Therefore Christians must:
Guard sound doctrine
Correct false teaching
Remain rooted in Scripture
Stay aligned with the gospel “once for all delivered” — Jude 3
Reflection
Truth is life‑giving. You can protect your faith by clinging to Scripture and the historic gospel.
