Keener on Paul 'avoiding' the words obey and rule -- argument from absent words

Keener argues Paul avoids the words 'obey' and 'rule' in Ephesians 5, and this avoidance is significant. Mike responds this is an argument from absence: Paul could be said to 'avoid' any word. There's no evidence he intentionally omitted these terms. Keener interprets the absence to mean all Christians submit to each other and love each other equally -- so there's nothing truly different between husband and wife callings.
