7. The underlying doctrinal motivation that inspires this document comes from the conviction that marriage is a value that takes its origin from the Creation and that it is rooted in human nature. "Have you not read that he who made them from the beginning made them male and female, and said, For this reason a man shall leave his father and mother and be joined to his wife, and the two shall become one?'" (Matthew 19: 4-5). Therefore, what the Church does for the family and marriage certainly contributes to the good of society as such and to the good of all. Furthermore, as an expression of the new life made possible by the Risen Christ, Christian marriage always expresses the truth about married love and is like a prophecy that clearly proclaims a human being's real needs: that man and woman are called upon from the beginning to live in a communion of life and love and that this complementarity will lead to strengthening the human dignity of the spouses, the good of the children and of society itself, through "...the defence and promotion of life...everyone's task and responsibility" (EV 91).
