Michael Schlatter (1716-1790), a Swiss of St Gall, sent to America in 1746 by the Synods (Dutch Reformed) of Holland, immediately convened Boehm, Weiss and Rieger in Philadelphia, and with them planned a Coetus, which first met in September 1747; in 1751 he presented the cause of the Coetus in Germany and Holland, where he gathered funds; in 1752 came back to America with six ministers, one of whom, William Stoy (1726-1801), was an active opponent of the Coetus and of clericalism after 1772.
Many churches and pastors were independent of the Coetus, notably John Joachim Zubly (1724-1781), of St Gall, who migrated to S.
Within the Coetus there were two parties.
The Coetus had actually assumed the power of ordination in 1772 and formally assumed it in 1791; in 1792 a synodical constitution was prepared; and in 1793 the first independent synod met in Lancaster and adopted the constitution, thus= becoming independent of Holland.
The principal organizations of the Church are: the Board of Publication (1844); the Society for the Relief of Ministers and their Widows (founded in 1755 by the Pennsylvania Coetus; incorporated in 1810; transferred to the Synod in 1833); a Board of Domestic Missions (1826); a Board of Foreign Missions (1838; reorganized in 1873), which planted a mission in Japan (1879), now a part of the Union Church of Japan, and one in China (1900).
