Not only did God destroy Sodom, but Matthew 18:15-17 shows that Jesus taught that Christian congregations are to ultimately expel unrepentant sinners.
In fact, 1 Corinthians 5:13 shows that Paul reflected on Jesus’ teaching of Matthew 18 by instructing the Corinthians to expel the sexual offender.
Paul later clarified in 1 Cornithans 15:33 that bad company corrupts good character.
catholic teaching seems to always fall short of the theologians here at Frre Republic
Suffice it to say that the catechism teaching is just fine Expelling is a weird term. Inncatholicism admonishing the sinner, instructing the ignorant and keeping good company, including not reading crappy books nor watching bad movies, is sufficient
Not good enough for the protestants who will endlessly seek fault with Catholicism but good enough for many
