I know what an unbeliever is...it is an unrepentant sinner. I was confused by your use of both in ascribing to two different camps.doulous said:An unbeliever is a person who has never been born again. I used "unrepentant sinner" to describe a professing believer who is in unrepentant sin. I believe the scripture clearly teaches (1 Cor. 11) that a believer can sin and be chastened by God if they do not repent. Of course, only God knows the heart and whether the professed believer who is in sin is actually a believer. The approach they have to dealing with sin in their life before coming to the Lord's table speaks volumes.
