What Casey does is not what dictates what our obligations and expectations as Christians are. God wants all to repent and come to Him and I pray that is what Casey does. “Forgive us as we forgive others” and all that.
A Christian has to CONFESS his sins and then ASK for forgiveness. Casey has not done that.
You might consider talking to Jesus about that. For he had plenty to say to the Sadduces and Pharasees and (they weren't seeking forgiveness either)...it wasn't pretty.
