Paul says he consulted NO ONE other than Jesus Christ in his instructions for his ministry...So it was from Jesus to Paul to elders...
Just as it was from Peter to likely the elders...
And when the scripture was completed, one can see it's all over the scripture for pastors, deacons, and anyone in leadership positions...
So no, I didn't cancatenate anything...My understanding is right on track...
Except your posting of Mat 16:18.
