Hey Steven,
It's a tough one really. The Google guidelines state that you should not add unnecessary details such as the business location:
Adding unnecessary information to your name (e.g. "Google Inc. – Mountain View Corporate Headquarters" instead of "Google") by including marketing taglines, shop codes, special characters, hours or closed/open status, phone numbers, website URLs, service/product information, location/address or directions or containment information (e.g. "Chase ATM in Duane Reade") is not permitted.
But I can also understand why you would want to add it, especially if they are located fairly close together as it would help users determine which church to search for.
