It is interesting they themselves recognize they are unclean.
The first reading on May 5 was from Acts 15. In verse 29 the word porneia (fornication) is mentioned among the particular prohibitions the new Gentile converts are being warned about...unfortunately the new translation obscures what the text says. I forget the exact wording but it was something like "irregular marriages."
Jewish morality was much stricter than Greco-Roman morality, so it is understandable that the converts would be admonished to avoid prostitutes (their pagan neighbors probably saw nothing wrong in going to brothels).
The most astute observation and comment on this thread! As freeper SAM comments,
most people are embarrassed and ashamed of their sins, habitual sins. don’t try to demand others tell them they are wonderful because of their sin. they don’t try to define themselves by their sinm. don’t spend their lives’demanding others pat them on the back for being such a good sinner. don’t demand laws protecting them because of their sins.
Shame has turned to pride, albeit through the legal system. Yet, subconsciously, as you well noted, they recognize their uncleanliness. No doubt the same is true for those who participate in abortions.
