When addressing a business envelope where the husband is Mr. and the wife is Dr., the proper way to format the names is to list the titles in alphabetical order. Therefore, you would address the envelope as "Dr. and Mr. [Last Name]." For example: "Dr. and Mr. Smith." This shows respect for both titles.
Addressing a husband and wife who are both Reverends: Reverends John & Jane Doe.
When addressing an envelope to the wife of a doctor who is not a doctor herself then and he is Dr. John Doe, then address the envelope to her as Mrs. John Doe or Ms. (Mrs.) Jane Doe.
If the letter/invitation is primarily to the reverend but also her husband: Rev. Mary Smith and Mr. John Smith If the letter/invitation is primarily to the husband but includes the wife: Mr. John Smith and Rev. Mary Smith If it is strictly a business letter and not church related: Mr. & Mrs. John Smith
The Revd. & Mr. X
How about Mr. and Mrs.
If you know the name of the husband, it is proper etiquette to address the mailing envelope to "Mr. and Mrs. [his name here]". On the inner envelope the addressing can be much more informal, with a simple "John and Jane", etc.Another PerspectiveThis is the twenty first century. Women have names and an existence apart from their husbands. An invitation can be addressed to Margaret and William Anderson. Most etiquette books are decades behind the times.
When addressing an envelope to a female pastor and her husband, you would typically write her name first, followed by her title. For example: "Rev. Jane Smith and Mr. John Smith." If you prefer a more formal approach, you can use "The Reverend Jane Smith and Mr. John Smith." Be sure to include their full names and any relevant honorifics, and place their names centered on the envelope.

* Addressing a female doctor and her husband: Mr. John Doe and Dr. Jane Doe.
It should read: Rev.(Ret.) Mary & Mr. Smith
Dr. Mary Smith and Mr. James Doe
The same way you would if her husband were still alive. Even though a woman's husband has passed, she still retains his name.
