The story in Genesis 17 and 18 of the Lord’s telling first Abraham and then Sarah that they would have a son in their old age is one of the places in Scripture where a “sin of omission” is often committed.
The complementarian conviction that women are under male authority and therefore must be excluded from (some) positions of leadership, rests in no small measure on their interpretation of God’s eternal, created order as established in Genesis 1-2.
Men and women struggle to understand each other and to thrive together as God intended. God’s design of an Edenic relationship where the male and the female together nurture and steward the earth rarely seems to happen.
Only as individuals, cultures, groups, and generations grasp the equality of females and males intended by God at creation can the legacy of pain inherited by all women from the fall continue to be reversed.
If God’s design for male-female relationships was unity and interdependence, and if hierarchy in relationships came as a result of sin, perhaps we need to reevaluate teachings on male “headship” in marriage today.
