In 1 Corinthians 5:5, handing over to satan for the destruction of the flesh is usually taken metaphorically as in removing the immoral man from the church.
However, in 5:13 Paul says “remove the wicked man from among yourselves.” This quotes multiple passages in Deuteronomy (17:7; 19:19; 22:21, 24; 24:7) which use this same phrase (LXX is identical). All of these passages except perhaps one (19:19) refer to putting one to death for serious sin.
Why would we not see this as Paul telling the Corinthian church to put this member to death “destruction of the flesh”, and then clarifying in case there was any uncertainty by saying “put away the evil from among you”?
Perhaps verses 9 & 11 are the basis for an excommunication interpretation, but the language in 13 seems very strong.
