I fear you are indulging in sola scriptura, an unfortunate heresy.  The bible may say all kinds of things, but we are taught by the One True Church  to call many men on Earth "father," all priests, and of course the popes a/k/a Our Holy Father.  So, you see, tradition replaces scripture.  That's how it works.  Many things in the bible have been tossed because Holy Mother church no  longer teaches those things.  It's all tied up with the infallibility of the Magisterium, tradition, and so forth.
