Sorry, but I can't accept that 'my father, my father' as an honorific title... or rather, as a basis for proof of a commonly used honorific title. It is an excited utterance under great stress. In fact, it is remarkable in it's uniqueness - if it were a common thing (as 'master' is), then we should see Elisha calling Elijah 'father' all the time.
