What does "the husband is the head of the wife" (Ephesians 5:23) mean?

This statement occurs between two calls for the wife to be subject (verses 22 and 24). The reason for submission is her husband's headship. The pattern for this headship is also mentioned: "even as Christ is head of the church." The headship of Christ, as explained in Ephesians 1:20-23 and 4:16, involves authority and supply. The same is true here. A husband's headship involves authority. Since Christ is the pattern, this will preserve the relationship from becoming tyrannical. His authority over the church is matched by His affection. His control is coupled with care. Such should also apply in the human relationship. Also, as the physical head supplies the human body with direction and nourishment, so the husband in his role of head gives his wife provision, protection, and guidance.
