In 690 St. Egbert sent Willibrord as head of a company of twelve monks to take the Gospel to the pagan lands around Frisia. The holy missionary first went to Rome to receive the blessing of Pope Sergius, then with his fellow-monks preached the Gospel throughout Holland.
In 695 Pope Sergius consecrated Willibrord Archbishop of Utrecht, instructing him to organize the Church throughout that area. As Archbishop, Willibrord continued to labor tirelessly for the spread of the Gospel in those pagan lands; his missionary travels took him as far as Denmark. He reposed in peace in 739 at Echternach Monastery (located in present-day in Luxembourg), having served for forty-four years as a bishop and for most of his life as a monastic. His tomb soon became a place of pilgrimage.
