To discriminate against a thoroughly upright citizen because he belongs to some particular church, or because, like Abraham Lincoln, he has not avowed his allegiance to any church, is an outrage against that liberty of conscience which is one of the foundations of American life. You are entitled to know whether a man seeking your suffrages is a man of clean and upright life, honorable in all of his dealings with his fellows, and fit by qualification and purpose to do well in the great office for which he is a candidate; but you are not entitled to know matters which lie purely between himself and his Maker.
