Restorationism in the context of "Unitarianism"

Western Christianity is one of two subdivisions of Christianity (Eastern Christianity being the other). Western Christianity is composed of the Latin Church and Western Protestantism, together with their offshoots such as the Old Catholic Church, Independent Catholicism and Restorationism.

The large majority of the world's 2.3 billion Christians are Western Christians (about 2 billion: 1.3 billion Latin Catholic and 1.17 billion Protestant). One major component, the Latin Church, developed under the bishop of Rome. Out of the Latin Church emerged a wide variety of independent Protestant denominations, including Lutheranism and Anglicanism, starting from the Protestant Reformation in the 16th century, as did Independent Catholicism in the 19th century. Thus, the term "Western Christianity" does not describe a single communion or religious denomination but is applied to distinguish all these denominations collectively from Eastern Christianity.

Memorialism is the belief held by some Christian denominations that the elements of bread and wine (or grape juice) in the Eucharist (more often referred to as "the Lord's Supper" by memorialists) are purely symbolic representations of the body and blood of Jesus Christ, the feast being established only or primarily as a commemorative ceremony. The term comes from the Gospel of Luke 22:19: "Do this in remembrance of me", and the attendant interpretation that the Lord's Supper's chief purpose is to help the participant prayerfully remember Jesus and his sacrifice on the Cross, and symbolically renew commitment.

This viewpoint is commonly held by Anabaptists, the Plymouth Brethren, many Restorationist denominations (such as Jehovah's Witnesses), some Baptists, Pentecostals, and most Non-denominational churches, as well as those identifying with liberal Christianity.

The United Society of Believers in Christ's Second Appearing, more commonly known as the Shakers, are a millenarian restorationist Christian sect founded c. 1747 in England and then organized in the United States in the 1780s. They were initially known as "Shaking Quakers" because of their ecstatic behavior during worship services.

Espousing egalitarian ideals, the Shakers practice a celibate and communal utopian lifestyle, pacifism, uniform charismatic worship, and their model of equality of the sexes, which they institutionalized in their society in the 1780s. They are also known for their simple living, architecture, technological innovation, music, and furniture. Women took on spiritual leadership roles alongside men, including founding leaders such as Jane Wardley, Ann Lee, and Lucy Wright. The Shakers emigrated from England and settled in British North America, with an initial settlement at Watervliet, New York (present-day Colonie), in 1774.
