It should be addressed as Rev and Mrs John Doe.
The envelope should be addressed to: Mr. & Mrs. John Doe (his wife should be included as deceased was her mother-in-law.)
An envelope should be addressed to "The Reverends John and Mary Doe" An acceptable alternate would be: The Reverends, Mr & Mrs John Doe"
"The Rev. and Mrs. (his first and last name)" would be the correct way to address an envelope to a pastor and his wife.
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.
I was always told that you never seperate a man's name. So, if you are addressing a card or envelope informally, and the couple is married, it should be addressed: Jane and John Doe
On the outer envelope it should read: PERSONAL Mr. & Mrs. John Doe c/o Zero Acme Co., 0000 Hawthorne St. San Francisco, CA ZIP CODE #
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
When addressing an envelope to a husband and wife it should be: Mr. & Mrs. John Doe. If either of the partners are a doctor, etc., then it would read Dr. & Mrs. John Doe or Pastor & Mrs. John Doe, etc.
