I cn’t think of anyone in your group that I would want to call
“instructor” so, no problem.
Again we are expected to imprint the limitations of English onto Scripture and accept what it gives us. It is similar to watching a modern High Definition movie on an old black and white TV. Father (πατηρ Pator) in Greek had three distinct meanings; genitor, metaph, and God. When Protestants tell us in English that we are to call no man "father" they are being way too vague to be taken seriously.
