How should Protestant clergy who prefer specific titles be addressed?

Protestant clergy who prefer specific titles should be addressed by their religious title because these titles reflect their role, responsibilities, and the respect associated with their position within the religious community. Using the correct title acknowledges their authority and the specific office they hold, which can vary from pastor and minister to reverend and elder. This form of address is essential in maintaining the decorum appropriate in a religious context and shows respect for their service and commitment to their faith.

In contrast, addressing them by first name may not convey the same level of respect or formal recognition of their office. Using Mr. or Mrs. could also fall short as these titles do not capture the spiritual or ecclesiastic nature of their roles. The choice of addressing them by "Doctor" alone is inappropriate unless the individual has earned a doctoral degree and prefers to be recognized in that manner; it disregards the specific religious title that they may prefer. Hence, addressing them properly by their religious title is the most respectful and appropriate choice.
