Reprobation, in Christian theology, is a corollary to the Calvinistic doctrine of unconditional election which derives that some of mankind (the elect) are predestined by God for salvation. Therefore, the remainder are left bound to their fallen nature and certain damnation. This same state of unbelief is also known as reprobation. In Calvinist terminology, the non-elect are often referred to as the reprobate. Similarly, when a sinner is so hardened as to feel no remorse or misgiving of conscience, it is considered as a sign of reprobation.
