I must ever believe that religion substantially good which produces an honest life, and we have been authorised by one, whom you and I equally respect, to judge of the tree by it’s fruit. Our particular principles of religion are a subject of accountability to our god alone. I enquire after no man’s, and trouble none with mine: nor is it given to us in this life to know whether your’s or mine, our friend’s or our foe’s are exactly the right.

Thomas Jefferson (1743-1826) American political philosopher, polymath, statesman, US President (1801-09)
