1 Corinthians 11:17-19

1Co 11:17 But as I give this command, I cannot show appreciation, because when you come together it is not for the better but for the worse.
1Co 11:18 Because first, I hear that there are schisms among you when you come together as a church, and to some extent I believe it,
1Co 11:19 because there must be groups with different preferences among you, so that those of you who are approved may become obvious.

1. Hairesis did not mean “heresy” in Paul’s day

The Greek word hairesis originally meant:

• a group
• a faction
• a school of thought
• a party within a larger community

It was used of:

• the Pharisees
• the Sadducees
• the Essenes
• the followers of various philosophers

None of these groups were considered “heretics” in the later, technical sense. They were simply identifiable subgroups.

Danker’s lexicon is right:
the later doctrinal meaning of “heresy” does not occur in the New Testament.

When English readers see “heresy,” they imagine false doctrine, damnable error, and theological rebellion. But Paul’s word simply described clusters of like‑minded people within a congregation.

2. Paul’s point: factions happen—but they reveal character

Paul acknowledges that such subgroups appear in many churches. People naturally gravitate toward those who share their preferences, practices, or personalities. That tendency is not automatically sinful. In fact, Paul says it can serve a purpose:

• It reveals who is genuine
• It exposes who is divisive
• It clarifies who is walking in love and who is not

In other words, differences can help the church discern maturity.

But that only works as long as the subgroups remain charitable and humble.

3. When does a subgroup become a destructive “heresy”?

A subgroup becomes dangerous when it stops being a preference and starts becoming a power play.

Paul’s concern is not that believers have different practices. His concern is when one group:

• tries to dominate the whole church
• demands conformity
• excludes or shames others
• elevates its own preferences to divine law

That is the point where hairesis becomes what 2 Peter 2:1 calls a destructive heresy—not because of doctrinal nuance, but because of divisive ambition.

The problem is not difference.
The problem is division.

The problem is not variety.
The problem is animosity.

The problem is not clarification of truth.
The problem is tearing the body apart.

4. Paul’s message: truth must be clarified, but unity must be preserved

Paul never feared honest disagreement. He welcomed it when it led to clearer understanding of the gospel. But he opposed any spirit that:

• weaponized differences
• created hostility
• exalted one group over another
• fractured the church into rival camps

Clarification is God’s will.
Factionalism is not.

Paul’s concern is always the same:
the church must be able to tell the difference between healthy diversity and destructive division.

And that remains just as necessary today.

LORD, keep us true to your word, and appreciative of our different approaches to it.
