The election of William Linn as Chaplain of the House on May 1, 1789, continued the tradition established by the Continental Congresses of each day's proceedings opening with a prayer by a chaplain. The early Chaplains alternated duties with their Senate counterparts on a weekly basis. The two conducted Sunday services for the Washington community in the House chamber every other week.
In addition to opening proceedings with prayer, the Chaplain provides pastoral counseling to the House community, coordinates the scheduling of guest chaplains, and arranges memorial services for the House and its staff. In the past, Chaplains have performed marriage and funeral ceremonies for House members.

From 1855 to 1861 the local clergy in the District of Columbia conducted the opening prayer. Thereafter, the House has elected a Chaplain at the beginning of each Congress.
