According to the Torah ( and ), the criteria for a person to be considered a prophet or speak for God in Judaism are that he must follow the God of Israel (and no other god); he must not describe God differently from how he is known to be from Scripture; he must not advocate change to God's word or state that God has changed his mind and wishes things that contradict his already-stated eternal word. There is no concept of the Messiah "fulfilling the law" to free the Israelites from their duty to maintain the "mitzvot" in Judaism, as is understood in much of Christianity or some Messianic Judaism.
