Wikipedia Overview

The history of popular religion in Scotland includes all forms of the formal theology and structures of institutional religion, between the earliest times of human occupation of what is now Scotland and the present day. Very little is known about religion in Scotland before the arrival of Christianity. It is generally presumed to have resembled Celtic polytheism and there is evidence of the worship of spirits and wells. The Christianisation of Scotland was carried out by Irish-Scots missionaries and to a lesser extent those from Rome and England, from the sixth century. Elements of paganism survived into the Christian era. The earliest evidence of religious practice is heavily biased toward monastic life. Priests carried out baptisms, masses and burials, prayed for the dead and offered sermons. The church dictated moral and legal matters and impinged on other elements of everyday life through its rules on fasting, diet, the slaughter of animals and rules on purity and ritual cleansing. One of the main features of Medieval Scotland was the Cult of Saints, with shrines devoted to local and national figures, including St Andrew, and the establishment of pilgrimage routes. Scots also played a major role in the Crusades. Historians have discerned a decline of monastic life in the late medieval period. In contrast, the burghs saw the flourishing of mendicant orders of friars in the later fifteenth century. As the doctrine of Purgatory gained importance the number of chapelries, priests and masses for the dead within parish churches grew rapidly. New "international" cults of devotion connected with Jesus and the Virgin Mary began to reach Scotland in the fifteenth century. Heresy, in the form of Lollardry, began to reach Scotland from England and Bohemia in the early fifteenth century, but did not achieve a significant following.
