By Bishop Joseph Strickland - The Pre-eminent Moral Mandate: The Right to Life... The most important foundational teaching and principle of Catholic Social Teaching is that every human life is sacred from conception to natural death, because every man and woman is created in the Image of God. Further, there is a fundamental Right to Life, which is confirmed in the Natural Moral Law, the Sacred Scripture, and the unbroken Tradition of the Catholic Church. Every Civil Law must respect that fundamental Human Right to Life, or such a law is an unjust law.
