text: I don't think it's merely a "small-t" tradition.  Those words attributed to Jesus (description of God as "Father") and which Christians consider Scripture belong to the larger Deposit of Faith and "large-T" Tradition.  I don't believe that Jesus could err - as God that would be impossible - and, again, He knew the cultural traditions into which he was being born.  If He'd wanted something different, there were other cultures available.
