I judge that a couple has an egalitarian marriage insofar as neither one makes any decision or takes any action that affects both without advice and consent of the other….
If a person does NOT agree with that, then I worry that he or she is in a hierarchical, dysfunctional relationship that both subjects truth to power and will lead to abuse (not necessarily physical, but not all abuse is physical).
Roger Olson: A final comment (for now) about complementarianism
When a person in a position of authority is manifestly wrong and a person under his or her authority is manifestly right, true authority belongs, in that instance, with the “underling.” For a Christian, especially, to assert the “rightness” of the authority of the person in the wrong just because he or she holds a position, is a betrayal of truth. It is the job of all lovers of truth to hold others, including those higher in the “chain of command,” accountable to truth. And it is the job of all lovers of truth to bow to it even when it is being communicated by someone lower in the “chain of command.”
