Ultimately, though, it is what happened in this first church building, and its larger 1951 successor on the same site, that matters. The ministers of this church have repeatedly had the opportunity to speak truth to power. In addition to Adams, Jackson, and Lincoln, other Presidents of the United States attended services to hear their preaching, including William Henry Harrison, James K. Polk, Franklin Pierce, James Buchanan, Andrew Johnson, Benjamin Harrison, Dwight David Eisenhower, and Richard Milhous Nixon, as well as members of their Cabinets, Congress, and the Supreme Court.
