and even revivalist in tone (especially in some conservative denominations), or strongly liturgical, approximating the practices of Lutheranism or more of Anglicanism (especially where Scottish tradition is esteemed), or semi-formal, allowing for a balance of hymns, preaching, and congregational participation (favored by many American Presbyterians). Most Presbyterian churches follow the traditional liturgical year and observe the traditional holidays, holy seasons, such as Advent, Christmas, Ash Wednesday, Holy Week, Easter, Pentecost, etc. They also make use of the appropriate seasonal liturgical colors, etc. Many incorporate ancient liturgical prayers and responses into the communion services and follow a daily, seasonal, and festival lectionary. Other Presbyterians, however, such as the Reformed Presbyterians, would practice a cappella exclusive psalmody, as well as eschew the celebration of holy days. Among the paleo-orthodox and emerging church movements in Protestant and evangelical churches, in which some Presbyterians are involved, clergy are moving away from the traditional black Geneva gown to such vestments as the alb and chasuble, but also cassock and surplice (typically a full-length Old English style surplice which resembles the Celtic alb, an ungirdled liturgical tunic of the old Gallican Rite), which some, particularly those identifying with the Liturgical Renewal Movement, hold to be more ancient and representative of a more ecumenical past.

The Lord's Supper (also known as Communion), in which Presbyterians believe in the Real Presence of Christ (pneumatic presence) in the spiritual sense, in the bread and wine through the Holy Spirit, as opposed to being locally present as in transubstantiation or consubstantiation. Architecture Some early Presbyterians, which were influenced by the puritan movement, were careful to distinguish between the "church," which referred to the members, and the "meeting house," which was the building in which the church met. Until the late 19th century, very few Presbyterians ever referred to their buildings as "churches." Presbyterians believed that meeting-houses (now called churches) are buildings to support the worship of God. The decor in some instances was austere so as not to detract from worship. Early Presbyterian meeting-houses were extremely plain. No stained glass, no elaborate furnishings, and no images were
