"I protect my right to be a Catholic by preserving your right to believe as a Jew, a Protestant, or non-believer, or as anything else you choose. We know that the price of seeking to force our beliefs on others is that they might some day force theirs on us. This freedom is the fundamental strength of our unique experiment in government. In the complex interplay of forces and considerations that go into the making of our laws and policies, its preservation must be a pervasive and dominant concern."
