I just noticed that the Martin Luther King Day quotes I linked to earlier are a collection of some of his most religious statements.

My heart throbs anew in the hope that inspired by the example of Lincoln, imbued with the spirit of Christ, they will cast down the last barrier to perfect freedom.

Those who advocate strict separation of church and state tend not to think of this connection between religion and government. Imagine the opposition there would be to a nominee for the federal judiciary who had written:

A just law is a man-made code that squares with the moral law or the law of God. An unjust law is a code that is out of harmony with the moral law. To put it in the terms of Saint Thomas Aquinas, an unjust law is a human law that is not rooted in eternal and natural law.
