Remember that many would have been illiterate. They did not &quot;deliver the letter&quot; until the congregation had been gathered together, in order to stop any chance of gossip after some had read the letter and others hadn't. These are the kinds of basic wisdom that are needed in pastoral and mission work.</p>
