Chapter 5
Immorality in the Church
Paul addresses sexual immorality and church discipline
"It is actually reported that there is sexual immorality among you, and of a kind that is not tolerated even among pagans…"
1 Corinthians 5:1
Chapter Overview
1 Corinthians chapter 5, "Immorality in the Church," stands at the heart of the apostolic teaching forming the theology and practice of the early church. Paul addresses sexual immorality and church discipline. Here the reader encounters not merely ancient history or religious instruction, but the living word of a God who speaks with purpose — weaving themes of immorality and church discipline into a narrative that addresses both its original audience and every generation since.
It is actually reported that there is sexual immorality among you, and of a kind that is not tolerated even among pagans, for a man has his father's wife. Your boasting is not good. Do you not know that a little leaven leavens the whole lump? Paul (or the epistle author) weaves together doctrinal argument and practical exhortation in a way that demonstrates correct belief and right living are inseparable. Theology that does not transform behavior is no theology at all.
The theme of immorality is not incidental here — it is the load-bearing pillar of the chapter's argument or story. Alongside it, church discipline operates as a clarifying lens, sharpening the reader's understanding of what God is accomplishing and why it matters beyond the immediate circumstances.
Looking across the wider biblical landscape, 1 Corinthians 5 does not stand alone. The interplay between immorality and judgment appears at critical junctures throughout Scripture — moments when God reshapes his people's self-understanding and renews his covenant claims on their lives. This chapter is precisely such a moment: a turning point where the reader is invited to see with fresh eyes what it means to be formed and held by God.
