As mentioned previously, I hope that some preachers will take up the challenge of preaching on Ephesians this coming summer.
Because of the liturgical context, some preachers might choose to avail themselves of the short form of the reading to avoid an erroneous association of the Ephesians passage with the “hard saying of the gospel of the day.
Too many years ago (forty?!) Daniel Harrington wrote enlighteningly of the Ephesians passage (in Interpretation, I seem to recall; I can’t put my hands on it now); and I have kept track of writing on it ever since. I’ve distilled my understanding onto the first link above, helped by A Profound Mystery: The Use of the Old Testament in Ephesians by Thorsten Moritz (Leiden: Brill, 1996). All depends on the main verb in verse 21: Be subject to one another and is bracketed by verse 33. What Moritz calls a digression is for Harrington (I seem to recall) the central point in verse 30: because we are members of his body.
Shall we have a civil conversation?
