From the article; "There's no doubt Catholic parishes have a lot to learn from their Protestant neighbors about how to throw out the welcome mat for people who perhaps have not darkened the door of a Catholic church in many years, if ever."

How true that is.

As a general rule, in a Catholic church, if you see a group of people either before or after Mass talking and being sociable, you can pretty much bet it is the "in crowd" enjoying each other's company and not taking time to include others. And that includes any priest involved in the conversation. Even if the priest wants to talk to others, the "in crowd" stymies that effort.
