1. Is it in the Bible?
Ac 20:29 For I know this, that after my departing shall grievous wolves enter in among you, not sparing the flock.
2. What do we believe it means?
Anyone who would speak against pastoral authority, or divide a church--is a "grievous wolf"
3. What does it really mean?
Perhaps I ought to sign my name "grievous wolf", for writing such foul stuff as this-!
Here once again, some words are taken out of Bible context and "fit" into the already established traditions and definitions of the church. the grievous wolves the Bible speaks of in Acts 20 were people who literally were persecuting believers and physically attempting to stop their meetings and apostleship.
Certainly God is against this, and we should be warned of people who would destroy the church. But--the point we are missing is that the church which the Bible is speaking of does not exist. The greatest attack that God would warn of would be an attack on the servant hood of all believers--and the functioning of apostleship--the example of Jesus--as the call for Christians to collectively strive toward.
I put forth an unusual opinion.
Perhaps the "grievous wolves" have already done their job--hundreds of years ago. Perhaps, Satan himself has tampered with the church--not destroyed it--but affected it--changed it--re-defined "ministry"--re-defined the functional plan the Bible sets forth--and now uses these Bible buzzwords to defend this incorrect operational plan!
