If one party outranks the other in terms of educational degree or professional or social standing then their name always appears first on both the envelope 'Dr.(R) and Mr.(A) Smith' and on the letter itself 'Dear Ruth and Alan' (if you are on a first name basis) or Dear Dr. and Mr. Smith (if not).
Get this! Instead of putting Mr. you put......DR. I KNOW! CRAZY!!

The proper way to address a Doctor of Osteopathic Medicine (DO) (not Doctor of Osteopathy) is Doctor (Dr.) since they are medical physicians.

Doctor.
If the Pastor who is the third and not a Junior is the only Pastor then you address him and his wife: Pastor & Mrs. John Doe. If all three were Pastors then you would address the letter as: Pastor John Doe,III & Mrs. John Doe.
You could address it to Reverend and Reverend Smith. The alternative would be the Reverends Smith.
What is the proper etiquette to addressing a Reverend in a letter?
Dear Mr. Guy and Dr. Girl
I am fairly certain that you would address the letter by listing the names alphabetically on separate lines on the envelope, and then follow with the address. Example: Mr. John Jones Mrs. Jane Smith 200 Nowhere Lane Anyplace, State 00000-0000 It is handled differently if one of the individuals has a title (such as a doctor)...but, I can't remember the rule for that one.
Mr and Mrs (last name here) David and Joan (last name here) (last name here) family
Dr. and Mr. Smith
