John Adams put it even more briefly...
"I could express my Faith in shorter terms. He who loves the Workman and his Work, and does what he can to preserve and improve it, shall be accepted of him."
- letter to Thomas Jefferson, 18 June 1812
Adams had the ambivalent and skeptical view of religion common to a lot of intelligent people. Check out this quote:
"Twenty times, in the course of my late reading, have I been upon the point of breaking out, 'This would be the best of all possible Worlds, if there were no Religion in it,' ! But in this exclamation I should have been as fanatical as Bryant or Cleverly [a minister and a schoolteacher, mentioned earlier in the letter]. Without Religion, this World would be Something not fit to be mentioned in polite company, I mean Hell."
- letter to Thomas Jefferson, April 19, 1817
The entire quote shows a man thinking hard about the subject, but not firmly in any camp. What's kind of funny is that I've seen each half of this quote, with the rest chopped off, used to "prove" in one case that Adams was an atheist, and in the other case that Adams was devoutly religious.
