Ethics philosophers have always focused on ethical conscience and how it was shaped. They seek to answer the question of whether conscience is an independent moral force or whatever is perceived by it is the same as the rules of practical reason? Psychologists have also talked about how external rules and regulations turn to internal ones for the individual. Assuming the acceptance of the truth of "moral conscience"، the present study examines the role of the mother with the religious approach and uses the findings of moral psychology and concluded that the best way to develop the sustainable traits of childhood is to develop moral conscience. In this paper، moral conscience is the ability to recognize the good and evil that triggers the practice of good and evil.

This paper seeks to explain the role of the mother in the issue of moral conscience formation and present a new model for the formation of moral conscience by presenting solutions in three areas of cognitive، emotional and behavioral (based on the giving of insight، deepening of beliefs and behavioral modification.
