First and foremostly.. I was spanked as a child. Always with love, restraint and never in anger. If my father felt the need to physically discipline, it was always with his hand,never angry, and never leaving marks more than redness,merely hard enough so i knew what I'd done wrong.
If my wife has something different in mind, I will look at it, but as I stand now, physical discipline without anger and consistently applied for certain behaviors, works just fine and as far as i can tell, is never spoken against within Scripture.
Now, four things to think over and perhaps clarify if you wouldn't mind, sister,
1) to tell me what i can't do because of my experience, before, telling me i need to look at scripture. Hmmm.
2) Comparing smacking your partner to disciplining your child is ludicrous. You are guiding children, a marriage is two people coming together to make one.
3) writing out bible verses as a form of punishment? associating Scripture to punishment rather than grace for trivial punishments? instead of anything else? even discipling your children physically? Interesting.
4) What studies are you citing with this? smacking children on the bottom can cause sexual arousal. Could you provide the case study involved? Do you think that maybe, if the issues underlined in said study, are there, (yes, im aware of these studies) perhaps it was from something other than merely being "smacked" in love, restraint, and without anger? Perhaps, nearly anything other?
