After the country had been evangelised by the itinerant monks and preachers, the next process was to establish a church in every village, and to provide a pastor to minister therein. Archbishop Theodore encouraged the thanes to build and endow churches on their estates, and introduced to this country the parochial system, by means of which all villages could have the services of a resident pastor. Then the thane's house was not considered complete without its chapel; and in the scattered hamlets and village communities churches arose, rudely built of wood and roofed with thatch, wherein the Saxon _ceorls_ and _cottiers_ loved to worship. The great Churchmen of the day were not content with such humble structures. They had travelled to Rome, and seen there some of the fine buildings dedicated for divine service; so they determined to have the like in their own country. One of these noble builders was Benedict Biscop, founder of the twin monasteries of Wearmouth and Jarrow. When he built the former, he imported foreign artists from Gaul, who constructed the monastery after the Roman style, and amongst other things introduced glazed windows, which had never been seen in England before. Nor was his new house bare and unadorned. He brought from Rome vast stores of church furniture, many books, and the "arch-chanter" John, to teach his monks the music and ritual of Rome. Aldhelm, Abbot of Malmesbury, and first Bishop of Sherborne, was one of the foremost church-builders of the time, and the beautiful churches at Malmesbury, Sherborne, Bradford-on-Avon, Frome, and Wareham, owe their erection to his instrumentality. Wilfrid also was one of the saintly architects of the period. Here is a description of the church of St. Andrew, at Hexham, taken from the writings of Richard, prior of the monastery there:--
