[Romulus]

Non-Catholics are not expected to call the Pope "Holy Father". Indeed, it would be incorrect, since it would imply a spiritual relationship that isn't really there. "Your Holiness" is always correct, however. Will that do?

Your Holiness

That's almost as offensive to me. Would Pope be ok?

I don't ever see an occassion to be in his presence but if I were would Sir be ok?
