From the speech:
It is important to recognize that while differences in theology exist between the churches in America, we share a common creed of moral convictions. And where the affairs of our nation are concerned, it’s usually a sound rule to focus on the latter — on the great moral principles that urge us all on a common course. Whether it was the cause of abolition, or civil rights, or the right to life itself, no movement of conscience can succeed in America that cannot speak to the convictions of religious people.
