You want to talk the Bible........is swinging (adultery) a sin or not?..........is this so hard? You sit here and criticize me for pointing out the obvious.
They are sinners, so are you, and so am I. Moral relativity is what you will have to engage in to show me that whatever sins the Van Dams may be guilty of, are worse than the sins that you and I are guilty of.
They are all sins, and we are all sinners in His eyes.
BTW, I like the way that you twist scripture to suit your need. Sometimes it's allegorical, others it's literal.
You and I (I think you anyway) both know what the tale of the adultress meant. Don't BS me.
