The community was descended from the pietisticSchwarzenau Brethren movement of Alexander Mack of Schwarzenau in Germany. The first schism from the general body occurred in 1728—the Seventh Day Dunkers, whose distinctive principle was that the seventh day was the true Sabbath. In 1732, Beissel arrived at the banks of Cocalico Creek in Lancaster County. Around this charismatic leader a semi-monastic community with a convent and a monastery was established, called "Ephrata". The members of the order were celibate. Members were required to sleep on wooden benches wide, with wooden blocks for pillows. They slept six hours per night, from 9 P.M. to midnight, and from 2 A.M. until 5 A.M., with a two-hour break to "watch" for the coming of Christ. They ate one small vegetarian meal a day. The only time the followers of Beissel were permitted to eat meat was during the celebration of communion when lamb was served. The members of the cloister spent much time at work or praying privately. Services every Saturday were led by Beissel, often being several hours long. During the time that this group formed, there was a hint of dissatisfied intellectualism of churches. Many wanted to be away from state established churches. Strict religious lives caused these brothers and sisters to come together to worship God in other ways. Instead of practicing their religion, they applied it by helping others to become more spiritual and celibate. Among the sisterhood and brotherhood there included a married order of householders, which were families who supported and engaged in the everyday activities. Other than practicing quiet lives by praying and doing charity work, the Cloisters had a duty to keep up with the tasks of living at Ephrata. Farming and industrial work were the typical workload on a daily basis. Although the Cloisters often practiced their religion by interpreting Biblical works, they also engaged in carpentry and papermaking. Other tasks included gardening, preparing meals, and mending. Not only were the cloisters famous for their writings and hymns on the printing press but they became very busy people especially when it came to chores. They manufactured clothing on a mill and kept their lives busy by creating duties and obligations. The Cloisters had a positive outlook on life; they respected their neighbors, land and environment. Education was also important in their society. It was important that every child maintain their education. Children that came from families were also encouraged to be educated in the German school. Educating the young was one of the charity works that the Cloisters accomplished. They also helped the poorby passing around bread to the poor families. Other believing families settled near the community, accepted Beissel as their spiritual leader and worshipped with them on Sabbath. These families made an integral part to the cloister, which could not be self-sustaining without them. The brothers and sisters of Ephrata are famous for their writing and publishing of hymns, and the composition of tunes in four voices. Beissel served as the community's composer as well as spiritual leader, and devised his own system of composition. The Ephrata hymnal was printed in 1747. The Ephrata Cloister had the second Germanprinting press in the American colonies and also published the largest book in Colonial America. The book, Martyrs Mirror, is a history of the deaths of Christian martyrs from 4 B.C. until 1660. Before the publication began at the request of a group of Mennonites from Montgomery County, it had to be translated from the original Holland Dutch into German, which was completed by Peter Miller of the Ephrata Community. Work began in 1748 and was finished about three years later. Many of the books were purchased by the Montgomery County Mennonites who had initiated the process. Beissel died in 1768, and this contributed to a declining membership. The monastic aspect was gradually abandoned, with the last celibate member dying in 1813. In 1814, the Society was incorporated as the German Seventh Day Baptist Church. Branches were established in other locations, some still surviving in 2009. In 1941, a Ephrata tract of land with remaining buildings was conveyed to the Commonwealth of Pennsylvania for use as a state historical site. The Pennsylvania Historical and Museum Commission led excavations there which, among other things, uncovered the Cloister's use as a Revolutionary War hospital. Of special note, the only glasstrumpet of its kind in North America was unearthed by archaeologists in 1998 at the Cloister. The trumpet, which likely came from Germany, was found in excellent condition which led archaeologists to believe it was intentionally buried. The mouthpiece was the only part missing from the trumpet, so it is unknown if it has ever been played. At its height, the Ephrata community grew to inhabited by about 80 celibate men and women. The married congregation numbered approximately 200.
