Addressing Envelope for Clergy

Dear Dr. Dave and Dr. Dee,

When addressing the envelope for clergy, do we need to write the title?

Signed,

Uptight

Dear Uptight,

For formal correspondence, the title goes with the full name. Because different denominations have different titles, here are some examples: Reverend John Doe, Father John Doe, or Rabbi John Doe

If married, then: The Reverend and Mrs. John Doe

If the woman is a clergyperson and the man is not, then write: The Reverend Jane Doe and Mr. John Doe.
