You are exactly correct; seeing them in person is very special. I have read and listened to the Copelands for years, and I've never heard them preach anything that I couldn't confirm in the Bible.
The distrust comes because people don't know what's in the Bible and they are too lazy to look it up and see if what the Copeland's are preaching is correct.
Then, when they get taken in by some shyster minister, it's all GOD's fault and ALL MINISTRIES are suspect. Typical.
I think mistrust comes when preachers act like idiots on tv, stamping and shouting and threatening and shaking fists. Makes one wonder who these people are who sit and take being treated that way.
Gloria Copeland is lovely. I can be open to her teachings because she behaves like a perfect lady. The shouters turn me very off.
