Actually, it was Christ who was called Rabbi by Nicodemus in John 3:

John 3:5 Jesus answered, Verily, verily, I say unto thee, Except a man be born of water and of the Spirit, he cannot enter into the kingdom of God.This is the primary connection it would seem to me. The appearance of "rabbi" in this context may have some significance but it's hard to tell.
