Vestments are liturgical garments and articles associated primarily with the Christian religion, especially by Eastern Churches, Catholics (of all rites), Lutherans, and Anglicans. Many other groups also make use of liturgical garments; among the Reformed (Calvinist) Churches this was a point of controversy in the Protestant Reformation and sometimes since, in particular during the Anglican ritualist controversies in England in the 19th century.
Origins of ecclesiastical vestments
In the early Christian churches, officers and leaders, like their congregations, wore the normal dress of civil life in the Greco-Roman world, although with an expectation that the clothing should be clean and pure during holy observances. From the 4th century onward, however, modifications began to be made to the form of the garments, and as secular fashions changed from the 6th century the church retained the original forms of their garments, although with separate development and with regional variations. Having separate, consecrated clothing for the ceremonies and rites in the churches emphasized the sacred nature of the functions the priest and ministers carried out at the altar. The Catholic Church's vestments had essentially established their final forms by the 13th century.
The Reformation brought about a new approach towards simplicity, especially under the influence of Calvinism. The Church of England experienced its own controversies over the proper use of vestments. On the other hand, Lutheranism largely retained many pre-Reformation vestments, especially in Scandinavia, e.g. Church of Sweden. The resulting varieties of liturgical dress are described below.
The rubrics (regulations) for the type of vestments to be worn vary between the various communions and denominations. In some, clergy are directed to wear special clerical clothing in public at all, most, or some times. This generally consists of a clerical collar, clergy shirt, and (on certain occasions) a cassock. In the case of members of religious orders, non-liturgical wear includes a religious habit.
