""We are obviously not semi-Pelagians," Patterson said. "We do believe that the entire human race is badly affected by the fall of Adam. However, we don't follow the Reformed view that man is so crippled by the fall that he has no choice.""
Like the Arminians (Semi-Pelagians) these guys underestimate sin.
Alternatively sin itself as a power (dominion) over man in his natural estate, prevails upon the sinner to prevent him perceiving all truth. This then may be the sign of an unconverted church goer!
