You scenario is somewhat glib, but it presupposes that the Apostle Paul and "...that church over there..." *must* have different or divergent messages. We, of the "church" I presume you're targeting, would beg to differ! ;-)
I'm not targeting anyone....I'm responding to the article this thread is based on.
I would prefer that the church and the words of the Apostle align.
My point is that IF there is occasion where they contradict, then the words of the Apostle bear greater weight.
