Why can’t the totality of all moral and religious norms, customs and traditions replace law?

Law, like morality, is a kind of result of social development, therefore, in their value orientations, they are close to each other. So, the concepts of legality and illegality of actions fixed in the law cannot seriously differ from the moral concepts of what is permissible and unlawful prevailing in society. Moreover, law and morality support each other in streamlining public relations, positively influencing the personality, forming a proper legal and moral culture, responsibility, and legal awareness among citizens. It is no accident that when applying the law in practice, one must remember that there is not only the letter, but also the spirit of the law, that the main task of law is to protect such a moral category as justice.
