Calvary Episcopal Church of Danvers, Massachusetts, has just announced it will begin offering a monthly worship service for dogs. Besides being driven to the service by Starbucks-jittered suburban elites in trademark Volvo station wagons, the canine faithful will enjoy the unique pleasure of being lived through vicariously. Perfect Paws Pet Ministry , as Calvary officials call it, will include a form of communion and prayers offered for the pets. While surely a natural outgrowth of American Episcopalianism, what really bugs me about it is the rank discrimination involved. Calvary Episcopal has announced that only well-behaved dogs may attend, and feline and equestrian companions are roundly excluded from the economy of salvation. Why not invite the local strays, or, better, invite them to preach?
