World Communion Sunday was started in 1940 as a Presbyterian-led initiative of the Federal Council of Churches toward ecumenical celebration of Communion by some Protestants in the United States on the same Sunday at a time when most U.S. Protestant denominations celebrated Communion infrequently (quarterly at most), and rarely on the same schedule. Not all churches involved in the Federal Council at the time chose to participate, but there was fairly strong uptake by Presbyterians, Methodists, Congregationalists (now known as UCC), and some Baptist groups at the time. These, in turn, generally promoted the idea across their missionary networks outside the United States so there would be more of a feel of worldwide Communion on that day, even if the practice was (and remains) in fact largely limited to a few U.S. Protestant denominations.
