But that’s not what he said. A personal achievement is something we accomplished. He’s saying his knowing God was something he did. That’s heresy.
The Reformation, as example, was Heresy under the judgment of the Roman Catholic Church.
Further, I cannot gainsay Leighton Flowers personal opinion concerning his coming to Christ.
He knows where he was when he found Jesus. Therefore, it could very well be a personal achievement for him. Achievement is also defined as something done through an act of courage. I don't think his remark qualifies as Heresy. But then again, according to the RCC I am a heretic, so there is that.
