Wolf – No one calls Shmule or Dovid or Sholmo with a title.
Titles BELITTLE the greatness.
Am I belittling Dovid or Shlomo if I add the title “HaMelech?”
Am I belittling Shmuel if I add the title “HaNavi” or “HaChozeh?”
Am I belittling Moshe if I add the title “Rabbeinu?”
Firstly, Godol MeRabbon Shmo is a chazal, so if there is a question, it is to CHazal.
But secondly, all the examples are NOT prefix but a suffix, you don’t ever say Rabi Moshe Rabbeinu, or Rabbon Dovid Hamelech or Rav Shmuel Hanovee.
(The prefix is a title while the suffix is the “job description”).
