For a New York Times article What is it About Mormonism?, the following lines which made me guffaw:
The framers recognized, of course, that a candidate’s religion (or lack thereof) would enter political debate, and they were prohibiting only a formal test for taking office. But they were also giving their imprimatur to Jefferson’s appealing notion that a person’s beliefs about religion were no more relevant to his politics than his beliefs about geometry.
Leaving aside jokes about the candidates debating whether the universe is open, flat, or closed, I’m guessing that the Renaissance man Jefferson would actually have cared quite profoundly about a candidate’s mastery of geometry.
Update: See this is exactly a case of extralusionary intelligence: Wim points out in the comments that the Virginia Statute of Religious Freedom included not just a reference not just to religion mattering no more than view on geometry, but also views on physics. Oh Thomas, why have you forsaken me?
