Here's one: You find yourself asking the clergy to take all the references to Jesus out of the service.
In 1987 we got married. My wife's name is Mary. I have since realized that priests may only get one or two Mary-and-Joseph combinations during a career. The local priest made the most of it.
We consider our union to be beautifully human -- in some places, strong, in other places, weak. But we are fully confident that our marriage is being perfected with each passing day.
