How should we understand and apply the New Testament texts about excommunicating and (perhaps) even shunning people? 1 Corinthians 5 tells the church not to eat with a so-called brother who is sleeping with his stepmother; 2 Thessalonians 3 and Titus 3 talk about having "nothing to do with" some sorts of people; 2 John urges us not to greet people who do not bring the right teaching; two passages talk about "handing over to Satan" a person who has sinned in a particular way; and of course Jesus talks in Matthew 18 about the need to treat unrepentant people like tax collectors. We might be confident of what these texts meant in their original context, or we might not, but how should we apply them now?
