Here one for y'all to consider. Are there still places where it's common to start off a City Council or Planning Commission meeting with a prayer or invocation? How about a prayer asking Jesus for forgiveness and salvation, or otherwise getting fairly specific with regards to a particular religious belief?
One place I worked had different religious leaders offer invocations before each city council meeting -- sometimes it was a rabbi, other times a Catholic priest or Muslim cleric. Folks got uncomfortable if a specific prophet was mentioned, but otherwise it was common practice.
