Have you ever paid attention to Romans 16? Twelve times, Paul commands his readers to “Greet” someone or a group of people.
Who did Paul intend to do the “greeting”? What did it mean for them to “greet” others? Who were they “greeting”?
I think, if we examine this passage (and other similar passages) closely, and we identify who Paul was talking to, who he was talking about, and what he intended them to do, then we would recognize how far we’ve come from the interactive and interrelational attitude of those early churches.
Today, we don’t even know one another… how could we possibly greet people who do not meet with us?
