Over the years, Torah Keepers have struggled with what title to use in reference to a Torah teacher. Should they just be called 'teacher'? What about 'pastor'? Some prefer the Jewish term 'Rabbi' while others wholeheartedly oppose it. This opposition typically stems from a verse in the Gospels.
Mattithyahu [Matthew] 23:8 - But do not be called Rabbi; for One is your Teacher, and you are all brothers.
Because of this, many in this walk have opposed the title, and I have personally witnessed numerous heated debates and arguments over the use of said title.
