2 Corinthians 13:10 shows Paul's authority is for building up, not tearing down — clarifying that the punishment here is restorative, not destructive.

1 Corinthians 5:5 specifies the punishment as delivering to Satan for destruction of the flesh — the very punishment Paul says is sufficient here.

Matthew 18:17 gives the church discipline process culminating in treating the unrepentant as an outsider — the procedure behind the punishment here.

In 2 Thessalonians 3:15, Paul says to admonish as a brother, not treat as enemy — reinforcing that church discipline aims at restoration.
