How should Military Chaplains be formally addressed?

Military Chaplains should be formally addressed as "Chaplain" followed by their rank and last name. This form of address recognizes both their military position and their role as spiritual leaders. Using "Chaplain" specifically honors their unique function as a member of the military who is dedicated to providing religious support, guidance, and care, regardless of denomination. Adding the rank serves to acknowledge their service and status within the military hierarchy, which is an important aspect of military protocol.

Individual preferences may exist, but in formal settings—such as in written correspondence, ceremonies, and official functions—this format is widely recognized and accepted for its clarity and respect towards both the individual’s military role and their religious vocation. The other choices would not convey the same level of respect or acknowledgment of their military status.
