Generally, it’s most respectful to call people what it is customary for them to be called. For example, I don’t consider an Jewish rabbi my teacher, but I would still call them “rabbi.” Or I don’t believe that Anglican bishops have valid holy orders, but I’ll still call them bishops.
Similarly, you’ll notice that non-Catholic politicians always call the Pope “His Holiness.” It’s just not respectful to deny a person their customary titles because you disagree with them.
Exactly! “When in Rome, do as the Romans do.” is the tradition, meaning that we do things out of respect for other cultures and make it a practice to be aware of these things. Thus, we don’t call a Catholic Priest “Sir,” but call him “Father.”
Protestant visitors to the Vatican, “VIPS”, people of all good faith, when meeting the Holy Father address him as “Your Holiness.” as in the above example given by** Aelred Minor.** Journalists follow this example when speaking of him as “The Holy Father,” or “Pope Benedict the Sixteenth”

etc. (or in print as Pope Benedict XVI."
While we are on the subject, :angel1:let’s clarify something regarding addressing protestant clergy, just to be al inclusive and grammatically savvy. I have heard this a number of times:
Example: Seeing the local minister nearby, a person says to another, “There goes the Reverend,” when what they should say is “There goes Reverend Farthingsworth,” or "There goes the minister, " or “There goes THE Reverend Farthingsworth.” Surprisingly, I saw examples of the above mistakes several times in the movie “Signs,” among other real- life examples such as “He’s our Reverend,” instead of the proper “He’s our minister, the Reverend Farthingsworth.”
Seeing him in person, it is correct to say “Good morning, Reverend Farthingsworth,” rather than “Hi, Reverend.” Often people will be heard to say “He is our Reverend,” when what they mean to say is “He is our minister,” or “He is our minister, the Reverend Farthingsworth.” (You may substitute “she,” if you like, for all those wanting to acknowledge that some protestants include the fair sex among their ordained clergy persons.)
I think it is always nice to act respectfully to people of all good cultures and faiths.:heaven: I’ve added “good” here, as there are, alas, some cultures whose basic political or social tenets may include obvious abuses of human rights. If pressed by chance to actually greet such a person, we have the right not to extend our hand nor to address them at all.
If writing something prepared for a journalistic review of such representatives, should they have a self- appointed title, we can choose quotation marks before and after whatever title is normally used, in order make our point known. I would use such a journalistic tactic when writing of the late "Reverend’ Jim Jones and the like, who was responsible for so many tragic deaths, although that choice would be a personal one. Language matters, and often makes possible a subtle allusion to another’s character that is a gentle but firm commentary.
Peace to all,:heaven::harp::grouphug:
