Senate
When the Senate first convened in New York City on April 6, 1789, one of its first orders of business was to appoint a committee to recommend a candidate for chaplain.

Since that time, the Senate has been served by chaplains of various religious denominations, including Episcopalians (19), Methodists (17), Presbyterians (14), Baptists (6), Unitarians (2), Congregationalists (1), Lutherans (1), Roman Catholic (1), and Seventh-day Adventist (1).
