Then there is supernatural authority. Which comes from the Church, and through the sacraments.
But the Sacraments have the true faith as their end.

Which means not only could a wife disobey her husband who refuses the resistance position, she could possible be justified in separating from him. As also a husband could shun his wife for the same.
