When the state does not place its power at the service of the rights of each citizen, and in particular of the more vulnerable, the very foundations of [the] state…are undermined.
Human life is sacred because from its beginning it involves the creative action of God and it remains forever in a special relationship with the Creator, who is its sole end. God alone is the Lord of life from its beginning until its end: No one can under any circumstances claim for himself the right directly to destroy an innocent human being.
Human life must be respected and protected absolutely from the moment of conception. From the first moment of his existence, a human being must be recognized as having the rights of a person—among which is the inviolable right of every innocent being to life.
God, the Lord of life, has entrusted to men the noble mission of safeguarding life, and men must carry it out in a manner worthy of themselves.
Before I formed you in the womb I knew you, and before you were born I consecrated you. Jeremiah 1:5
