Ma`rifat Adyan

Having a behavioral and moral system in the relations between individuals, communities and nations is necessary. Considering the completeness of the religion of Islam and the completion of the mission of the prophets of God, it is expected that this religion works in a systematic way in interaction with other religions, especially the People of the Book who believe in one God and the divine book. This issue, for reasons such as the abundance of followers of Christianity, the historical interaction of Islam with them and the confrontations that Jews have had with Muslims, becomes more necessary in relation to Christians. Certainly, designing a moral system without considering the theory of "value" makes that moral system meaningless. Therefore, before anything in interaction with Christians, it is necessary to explain the theory of "value" in relation to them. From the point of view of Islam, the purpose of human creation is to reach the position of closeness to God through worshiping and serving God alone. Using analytical-descriptive method and foucsing on the verses of the Holy Qur'an, this paper seeks to show how to achieve this goal, as the most complete way to reach real perfection and happiness in relation to Christians.
