But a day late. Apparently I'm a Second Day Adventist. Anyway, 1 Corinthians 5 is usually misunderstood. Paul berates the Corinthians because he has heard that one of them is boinking his father's wife, and they apparently all think this is just fine and dandy. Even Skeptics Annotated Bible doesn't get what's really happening here, presuming that woman is the man's stepmother. No she isn't.
Remember that men could have more than one wife. The story of co-wives Leah and Rachel is well known. Solomon supposedly had hundreds of wives. I expect that polygamy was less common in the first century but since the Torah law was still accepted and Rabbinical Judaism had not emerged it was presumably perfectly legal and acceptable. Furthermore, women had to be married. Yes, Boaz was evidently a nice guy and there was fondness between Ruth and Boaz, but she set out to seduce him and get him to marry her because her alternative was abject poverty. That she picked a much older wealthy man was a sensible choice. (We would call her a trophy wife.)
Note further that the sin of Onan is almost always misconstrued. That he spread his seed on the ground does not mean that he masturbated, it means that he practiced coitus interruptus in order not to impregnate his brother's widow. Torah law required men to marry and impregnate their brother's widows in order that a) the widow would not end up like Ruth before she married Boaz, subsisting on charity and B) so that the man's lineage would continue. That's what marriage was all about.
So likely what happened here is that an old man took a young second (or possibly higher order) wife, and when he died she developed a relationship with his son, to whom she was biologically unrelated. his was perfectly natural -- presumably they were of a similar age, he had inherited the estate, so it meant she could stay in her home and be with the man with whom she already had at least a friendship if not romantic feelings. It seems perfectly right for the Corinthians to be happy about this benevolent outcome, but excoriates them because it is contrary to the Torah law.
Paul also is harshly judgmental in general and calls upon them to expel and shun sinners. This is after he has gone to great lengths in Romans to say that everyone is a sinner and that we cannot be saved by good works but only by the grace of God, i.e. believing in the whole Jesus myth, in which case your sins will be forgiven. So which is it?
All this also serves to remind us that cult leaders are generally narcissists, and furthermore that they frequently contradict themselves and that their followers engage in doublethink in order to accept the contradictions. Hmm. Remind you of anybody?
5 It is actually reported that there is sexual immorality among you, and of a kind that even pagans do not tolerate: A man is sleeping with his father’s wife. 2 And you are proud! Shouldn’t you rather have gone into mourning and have put out of your fellowship the man who has been doing this? 3 For my part, even though I am not physically present, I am with you in spirit. As one who is present with you in this way, I have already passed judgment in the name of our Lord Jesus on the one who has been doing this. 4 So when you are assembled and I am with you in spirit, and the power of our Lord Jesus is present, 5 hand this man over to Satan for the destruction of the flesh,[a][b] so that his spirit may be saved on the day of the Lord.
6 Your boasting is not good. Don’t you know that a little yeast leavens the whole batch of dough? 7 Get rid of the old yeast, so that you may be a new unleavened batch—as you really are. For Christ, our Passover lamb, has been sacrificed. 8 Therefore let us keep the Festival, not with the old bread leavened with malice and wickedness, but with the unleavened bread of sincerity and truth.
9 I wrote to you in my letter not to associate with sexually immoral people— 10 not at all meaning the people of this world who are immoral, or the greedy and swindlers, or idolaters. In that case you would have to leave this world. 11 But now I am writing to you that you must not associate with anyone who claims to be a brother or sister[c] but is sexually immoral or greedy, an idolater or slanderer, a drunkard or swindler. Do not even eat with such people.
12 What business is it of mine to judge those outside the church? Are you not to judge those inside? 13 God will judge those outside. “Expel the wicked person from among you.”[d]
