"The life of the father is like the life of the son. Only the one who sins shall die."
-- Ez 18: 1-10, 13b, 30-32
"Human life is sacred because from its beginning it involves the creative action of God and it remains for ever 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 circumstance claim for himself the right directly to destroy an innocent human being."
-- CCC 2258
