 The Catechism states : " 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 . ... no one can under any circumstance claim for himself the right directly to destroy an innocent human being . " Direct and intentional killing of an innocent human is considered a mortal sin . Considered by the Church to be of an even greater gravity is the murder of family members , including " <unk> , <unk> , <unk> , the murder of a spouse and procured abortion . "
