Some Christians in Ephesus--Paul singles out two leaders, Hymenaeus and Alexander (v. 20)--made this mistake (and Paul's language, rejected and blaspheme, suggests that it was a conscious one), with devastating results to their relationship with God. Shipwrecked raises images in the mind of "destruction," not "setback." Furthermore, the disciplinary measures taken are severe. Handed over to Satan refers to excommunication from the church back into Satan's realm. We should not misunderstand the nature of this process. It was not simply intended to "cut out a cancer" in order to preserve the rest of the body, as some churches view it today. Neither is it a practice that the church today can afford to ignore, as if it were an aberration belonging to the Inquisition. Taken together, Matthew 18:15-17, 1 Corinthians 5:5, 2 Corinthians 2:5-11 and 2 Thessalonians 3:14-15 reflect the development of a carefully measured process. Each step was designed to bring the erring individual to the point of admission and true change of mind and behavior. Even if the individual persisted in a stubborn refusal to change (like the two mentioned here), the final step of expulsion from the fellowship back into the hostile world was ultimately intended as a means (desperate and last-ditch though it be) of reclamation. To be handed over to Satan (compare 1 Cor 5:5) is to be exposed, without the protection God promises to his people, to the dangers of sin. For some it takes being cast off into the sea to realize the advantages on board ship.
