In his letter to the Ephesians, Paul amplifies what he says to the Colossians in fewer words, wherefore the first named is longer. But why does this matter? It matters because of the argument that mutual submission is found only in Ephesians but not elsewhere, wherefore husbands should not submit to their wives. But if these two letters are identical - and they are - and submission is mutual and voluntary in Ephesians, husbands cannot be excluded from submitting to their wives in Colossians. If want to exclude husbands from submission in Colossians - and elsewhere - we must also agree that wives should not love (agape) their husbands since such directive is not found in either of the two letters.
