The impression I got from this passage is that only God has authority over us. I did not see any mention to the elders appointed by the church, which is why i included that verse. What you mean by 'lord over others' can be interpreted in various ways.
Right. That is what I believe. Only God has authority over us.
The verse you mention appears to say otherwise. So what?

just kidding..
Very interesting subject and I appreciate your kindness in not
just blowing me off as a kook before giving me a chance to clarify.
Unless we know each other better than I originally thought..
17Obey(A) your leaders and submit to them,..
Who is your leader? Who chose him as your leader?
(Sort of a rhetorical question unless you dont believe
that chooser to be God)
for they are keeping watch over your souls, as those who will have to(C) give an account.(D)
Tells us why we should obey and submit to them, which also helps us to
know how far we should go in obedience and submission. (consider the
scandals in the news even as we speak

.. what would you tell those
kids about obeying and submitting to priests? kwim now?)
Let them do this with joy and not with groaning, for that would be of no advantage to you.
Amen. It's all bout you! (sounds good?! lol)
I do believe that i am the only one who can determine who "my" teacher
is and also we can have more than one mentor or teacher.. God is generous
and if we're hungry and seeking more and more, He'll accomodate us
Don'tcha think?
Again, all my own opinion based on what I've understood from Scripture and experience...
I try to look at all things through a lens of logic and application...
Thanks again ...
God bless you!
