If I type "church" into a Google Map the results are plentiful. In fact, just around the corner from where I live there are two churches literally side by side (see photos below).
This modern phenomenon always causes me to wonder: what would Jesus have said if Jews in his day built two synagogues side by side? What would Paul have said if two Jewish Christian communities existed side by side yet never talked to one another?
