CCC 2270 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.1
Before I formed you in the womb I knew you, and before you were born I consecrated you.2
My frame was not hidden from you, when I was being made in secret, intricately wrought in the depths of the earth.3

CCC 2584 In their “one to one” encounters with God, the prophets draw light and strength for their mission. Their prayer is not flight from this unfaithful world, but rather attentiveness to The Word of God. At times their prayer is an argument or a complaint, but it is always an intercession that awaits and prepares for the intervention of the Savior God, the Lord of history.4
