Observations on romantic love: the husband is to love his wife as Christ loved the Church and gave His life for her.
Love necessarily requires sacrifice. However, there is an important distinction between sacrifice for the bride and sacrifice to the bride. The former is what Christ does. It maintains the proper structure of authority and headship found in the Bible. On the other hand, the latter reverses the authority structure, and corrupts the symbol.
When a man sacrifices for a woman he loves—when he is willing to give up convenience, comfort, and life for her—he is properly reflecting Christ. However, when he gives in to her every whim and becomes subservient he has ceased to reflect the truth of Christ and the Church. He is now sacrificing to her and has crossed the line into idolatry.
