[noe-eht’-ik] (Greek noesis, “understanding” from Greek nous, “mind”)
The concept in Christian theology that argues for the negative effect of sin on the minds of all people. This effect changes man’s thinking and ability to understand. It is not that the mind is incapacitated, but that sin has a deteriorating effect on our ability to think and believe. This effect is primarily seen with regard to our understanding and perception of spiritual things. All Christian traditions believe that sin has debilitated the mind, but some will differ with respect to the degree or what the remedy is.
