In my version, you are talking to your father directly. Breandán's version works better if you want to tell the world that your father is your protector and mentor (you are talking ABOUT him, not TO him, if that makes sense).
Yes, good point, Mick.
I assumed this was a description "(You are/this is) my protector, my mentor, my father", which I think still applies, but Mick's version is talking directly to your father actually calling him those names ("Father, may I borrow the car?" "My Lord, I beseech thee." - except it isn't archaic in Irish.)
