I have often thought of my former "shepherd" like Saul before he became Paul. He has so much passion to serve God and he does it 100%. But does this mean I am to ignore the false teachings he instilled in me because he loves God so much and is trying so hard? Am I, as his supporters would suggest, to support his ministry because "his heart is in the right place"? His greatest misstep was teaching us (implicitly) that HE, instead of Christ, was the only mediator between God and man. And so, even though he has great passion for God and I'm sure he's trying to do the right thing, it's not pleasing to God. I still hope God will stop him in his tracks someday and say, "Why are you persecuting me?"
Passion and good motives still don't make abuse in the church acceptable. Not for Saul, and not for us.
