The life of St Willibrord of Utrecht
Five years into that mission Pope Sergius consecrated him archbishop in Rome, giving him the name Clement and the charge of organizing a church throughout Frisia from a seat at Utrecht.
He gave the rest of his long life to that work, his travels as a missionary reaching as far north as Denmark. Around 698 he founded the abbey of Echternach, in what is today Luxembourg, which became both a center of his mission and, in time, his own resting place. He died there in 739, having served forty-four years as bishop and having given the Frisian and Dutch lands their first sustained encounter with the Gospel.
He is remembered as the first bishop of Utrecht and as the apostle who brought Christian faith to a people who had not known it, his relics still honored at the abbey he built. His place in Orthodox commemoration reflects the veneration of saints of the pre-schism West kept by some jurisdictions, notably the Russian Orthodox Church Outside of Russia, rather than a fixture of every local calendar.
