Bishop of Utrecht, Apostle of the Frisians, and son of Saint Hilgis, born in Northumbria, 658; died at Echternach, Luxemburg, 7 November 739. Willibrord made his early studies at the Abbey of Ripon near York, as a disciple of Saint Wilfrid, and then entered the Benedictine Order. When twenty years old he went to Ireland and spent twelve years in the Abbey of Rathmelsigi (identified by some as Mellifont in Co. Louth) under Saint Egbert. From him Willibrord and eleven companions received the mission to Frisia, at the request of Pepin. They came to Utrecht but did not remain there, repairing to the court of Pepin. In 692 Willibrord went to Rome, received Apostolic authorization, and returned to his missionary labours. At the wish of Pepin he went for a second time to Rome, was consecrated Bishop of the Frisians by Sergius III (21 November 695) in the Church of Saint Cecilia, and given the name of Clement. He also received the pallium from the pope. On his return he laboured among the people assigned to him; to raise recruits for future apostolic work he founded a monastery at Utrecht, where also he built a church in honour of the Holy Redeemer and made it his cathedral. In 698 he established an abbey at the Villa Echternach on the Sure; this villa had been presented to him by Saint Irmina, daughter of Saint Dagobert II, the donation being legally confirmed in 706.
When Radbod gained possession of all Frisia (716) Willibrord was obliged to leave, and Radbod destroyed most of the churches, replaced them by temples and shrines to the idols, and killed many of the missionaries. Willibrord and his companions made trips between the Maas and the Waal, to the North of Brabant, in Thuringia and Geldria, but met with no success in Denmark and Helgoland. After the death of Radbod he returned (719) and repaired the damages done there, being ably assisted in this work by Saint Boniface. Numberless conversions were the result of their labour. Willibrord frequently retired to the Abbey of Echternach to provide more particularly for his own soul; he was buried in the oratory of this abbey, and after death was almost immediately honoured as a saint. Some relics were distributed in various churches, but the greater part remained at the abbey. On 19 Oct., 1031, the relics were placed in a shrine under the main altar of the new basilica. His feast is celebrated on 7 Nov., but in England, by order of Leo XIII, on 29 November. Since his burial Echternacht has been a place of pilgrimage, and Alcuin mentions miracles wrought there. The old church was restored in 1862 and consecrated in September 1868. Another solemn translation of the relics took place on 4 June 1906, from the Church of Saint Peter to the new basilica. On this occasion occurred also the annual procession of the holy dancers. Five bishops in full pontificals assisted; engaged in the dance were 2 Swiss guards, 16 standard-bearers, 3045 singers, 136 priests, 426 musicians, 15,085 dancers, and 2032 players.
No writing can with certainty be attributed to Saint Willibrord except a marginal note in the Calendar of Echternach giving some chronological data. The Life was written by Alcuin and dedicated to BEORNRAD. (Abbot of Echternach). He probably made use of an older one written by a British monk, which is lost. This was used also by THEOFRIC.
