Each semester I assign students in my online class (Exploring the Christian Faith) to attend a Christian church service dissimilar from their own tradition. If they don’t have a church background, I give them some ideas and I also encourage Protestants to visit a Catholic or Orthodox church (and vice versa) if they haven’t been to one. It’s been a great assignment and students have done well with it.
One student went to a large church and she said that the ushers were “friendly but not inviting.” You know those moments; though there were smiles, handshakes, and warmth, she never felt like they wanted to know her. There was no empathy, just a performance.
