Passage: Present-day Christian religious bodies known for conducting their worship services without musical accompaniment include some Presbyterian churches devoted to the regulative principle of worship, Old Regular Baptists, Primitive Baptists, Plymouth Brethren, Churches of Christ, the Old German Baptist Brethren, Doukhobors the Byzantine Rite and the Amish, Old Order Mennonites and Conservative Mennonites. Certain high church services and other musical events in liturgical churches (such as the Roman Catholic Mass and the Lutheran Divine Service) may be a cappella, a practice remaining from apostolic times. Many Mennonites also conduct some or all of their services without instruments. Sacred Harp, a type of folk music, is an a cappella style of religious singing with shape notes, usually sung at singing conventions.

Passage: Like much of the south Atlantic region of the United States, Jacksonville has a humid subtropical climate (Köppen Cfa), with mild weather during winters and hot and humid weather during summers. Seasonal rainfall is concentrated in the warmest months from May through September, while the driest months are from November through April. Due to Jacksonville's low latitude and coastal location, the city sees very little cold weather, and winters are typically mild and sunny. Summers can be hot and wet, and summer thunderstorms with torrential but brief downpours are common.

Passage: The chapter house has an original mid-13th-century tiled pavement. A door within the vestibule dates from around 1050 and is believed to be the oldest in England.[citation needed] The exterior includes flying buttresses added in the 14th century and a leaded tent-lantern roof on an iron frame designed by Scott. The Chapter house was originally used in the 13th century by Benedictine monks for daily meetings. It later became a meeting place of the King's Great Council and the Commons, predecessors of Parliament.
