Let me lay it out again:
Proponents of wife-beating rely upon the fact that it is generally permitted for a superior to physically discipline a subordinate.
But proponents of wife-beating do not take into account that the husband-wife relationship is not a simple superior-subordinate relationship.
God requires that husbands HONOR their wives.
In other situations where honor is required, honor precludes the use of physical violence because it's degrading to the one receiving it and incompatible with honor. So, for instance, it's considered a heinous act for a child to strike his parent.
OBJECTION: But it's wrong for a child to strike his parent because that's the case of a subordinate striking an inferior.
RESPONSE: No, it's not simply wrong, but a heinous act for a child to strike his parent. While it would be wrong for a soldier to strike his commanding officer ... under most circuмstances, it's not the same egregious and heinous act as that of a child striking a parent. Why? Because the latter represents a violation of the honor which children should have towards their parents.
Now the burden of proof is on the pro-wife-beaters to demonstrate that there's a valid distinction in types of honor that would on the one hand allow a husband to strike his wife while at the same time forbidding a child from striking his parent. Until such a distinction is proven without a doubt by wife-beating advocates, Catholics should consider it forbidden and incompatible with the honor owed by a husband to his wife to lay violent hands on her.
So, Jaynek, where's the "weakness" of this argument? Answer: it's only in your mind because you're emotionally invested for some reason in the opposite position. You simply keep parroting back over and over again how various Catholic authorities have considered it permissible. But I'm arguing that they're wrong ... because they forgot something. None of these authorities answered the objection I've made: What about "honor" in a husband-wife relationship? Since they failed to address that objection, I consider their positions to be unproven and invalid.
