Addressing formal envelopes

How do I address an envelope for a formal wedding rehearsal dinner to two Methodist ministers? In other words, both the husband and wife are ministers.
Thank you

It would be suitable (in my opinion) to say:

Mr. and Mrs. So and So

~R

I think, based on how you do it if both are doctors, you list the woman first, and list both titles.
The Reverend Mary Dillworth Smith
The Revevend John Smith

If one (or both) is "The Reverend Doctor" you should include that.

Often, the companies that produce wedding invitations have helpful stuff on their Web sites for things like this.
