The F Street Church was established in 1803 with James Laurie as pastor by leaders of the Associate Reformed movement, known as Covenanters, who had seceded from the Church of Scotland in the mother country and retained a separate identity in North America. After holding initial worship services in the U.S. Treasury building, in 1807 the congregation began meeting, still under the leadership of Dr. Laurie, in an imposing brick building that stood where the F Street entrance to the Willard Hotel today opens on to Peacock Alley—just two blocks from the church's present location on New York Avenue between 13th and 14th Streets, NW. The F Street Church, or Willard Hall, was one of the first buildings erected in Washington for Protestant worship. In 1824 Laurie led the congregation out of the Associate Reformed Presbyterian group to join the Presbyterian Church in the United States of America (PCUSA), which represented the mainstream of American Presbyterianism descended from the state-established Church of Scotland.
