I have another question (if you don’t mind) while I continue to think about Ephesians 5.
I can understand the concept of mutual submission from Eph 5:21 and how the the husband submits to his wife by loving her sacrificially.
I can understand that “submit” doesn’t imply that there is authority.
My question regards the meaning of “head” in this passage. If I use the context to work out the meaning of the head/body metaphor the head loves, feeds, cares for the body and is united as one with the body. There is no mention of authority. But if I go back to Eph 1:20-23 the head/body metaphor seems to be associated with authority. Is Paul using the metaphor in different ways within the one letter? Does anyone have any thoughts on this?
TIA.
