Addressing a Husband and Wife Who Are Ministers
When addressing a letter to a husband and wife who are both ministers and are both referred to as "Reverend," how should they be addressed? Does the wife's name come first?
The appropriate way to address a letter to a husband and wife who are both ministers is: The Reverends Mary and John Smith. The wife’s name always comes first.
One other thought about honorific titles: If you're unsure of how to address someone with a doctorate, follow this general rule of thumb. It's better to "Dr." a person who would rather be referred to as "Mr." or Mrs." than to do the reverse.
