I believe that distinctions in masculine and feminine roles are ordained by God as part of the created order, and should find an echo in every human heart.
Further I think Adam's headship in marriage was established by God before the Fall, and was not a result of sin.
In a marriage lived according to these truths, the love between husband and wife will show itself in listening to each other's viewpoints, valuing each other's gifts, wisdom, and desires, honouring one another in public and in private, and always seeking to bring benefit, not harm, to one another.
