Lynn Cohick claims seeing authority in headship 'violates Paul's intention in metaphor'

Lynn Cohick argues that to see headship as implying authority is to 'violate Paul's intention in metaphor.' She also claims kephale 'typically refers to the physical head resting on the neck' and that while it can be used metaphorically for 'leader' in Hebrew, Latin, and English, 'it is difficult to make the case that it refers to leader in Greek, for we have almost no evidence of this.' Mike notes she provides no footnote for the claim about violating Paul's intention.
