Yes, face to face is a figure of speech meaning to speak to someone in person, not through written correspondence or (in modern times) via electronic communication (although video chat could be considered face to face by some).
But that is completely beside the point, we are not discussing "face to face". We are discussing Scripture, and you have given no proof that any of the figures of speech in Scripture mean other than what they say.
Please give direct evidence, not your opinions, that prove Christ is not God.
