Late yesterday, the U.S. bishops released their weekly smackdown of a prominent American Catholic pol. And Washington’s Archbishop Wuerl added his own voice, in a letter to his priests:

Our Catholic faith proclaims what is already written in our human hearts and recognized in our conscience – to kill innocent human life is wrong. The commandment “you shall not kill” is, as the Catechism of the Catholic Church tells us, “a privileged expression of the natural law” (2070). Modern science has demonstrated beyond any doubt that this innocent human life begins at conception. Defense of innocent human life is not an imposition of personal religious conviction but an act of justice.

Read the whole thing. You owe it to yourself. So, for that matter, does the senator from Delaware.
