After laying out his reasoning, Paul concludes by appealing to the universal practice of the churches. Commentators explain this isn't just a demand for conformity, but a call for the Corinthian church to maintain peace and unity with the wider body of Christ. Rather than insisting on a unique or disruptive practice, they should respect the established, orderly customs of other believers. The Christian religion, scholars note, often sanctions local customs that align with truth and holiness.
