Born in.....

The phrase Born in sin, come on in... was either said or quoted by S. King in his movie Storm of The Century. I'm not sure however, if it was mentioned in his novel (being that your read it in a book).

"Born in sin, come on in. Born in lust, turn to dust. Born in vice, say it twice." Andre Linoge, a character in Stephen King's "Storm of the Century."

I don't know if that's an old saying or if Mr. King made it up.
