"The rights of some individuals are affirmed at the cost of the fundamental right to life of another individual. This is why every legalization of abortion implies the idea that law is based on power...
"...No one denies that the concrete existential situation in which the decision is reached to have an abortion can sometimes be dramatic. Nevertheless, it is a fact that this claim to exercise real rights is demanded to the detriment of the life of an innocent human being whose rights are not even taken into consideration. In this way, one becomes blind to the right to life of another, the smallest and weakest person involved, one without a voice."
Joseph Ratzinger, 1997 Address to the Pro-Life Movement, in Christianity and the Crisis of Culture, San Franscisco: Ignatius, 2006, 62-63.
"We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness. — That to secure these rights, Governments are instituted among Men, deriving their just powers from the consent of the governed, — That whenever any Form of Government becomes destructive of these ends, it is the Right of the People to alter or to abolish it, and to institute new Government, laying its foundation on such principles and organizing its powers in such form, as to them shall seem most likely to effect their Safety and Happiness."
