If God were invisible and Jesus says he “is the image of God,” then why was Jesus visible? If you were going to argue with concrete thinking, then you must end with concrete thinking. Unless the image was referring to another framework such as behavior and attitude of which both males and females are capable of emulating. How many fathers have told their daughters, “ You are just like me” or daughters wishing “ to be just like my dad?”
Unless egocentric and concrete thinking are preventing a higher level of interpretation, that is. Of course, someone who is into male headship cannot think of otherwise, even if he tried his best.
