You oversimplify a mystery of the faith.
"Seek and ye shall find"
Remember, the Church is not Calvinist, and has remained on the horns of the debate for over a thousand years, never veering too far in that direction, or toward pelagianism.
So, yes, even after being heretical, a person may be reconciled to the faith if they recant, and this has happened.
Now...will everyone quit picking at one small issue that was not my point at all? You asked for a critique of your linked article. I took the time to do that. If you have lost interest, at least let me know so I can move on. Thx.
