Upon the death of Archbishop Cornelius van Steenoven on April 3, 1725, Barchmann Wuytiers was unanimously elected by the Chapter of Utrecht on May 15, 1725 to fill the vacant see. As in the case of Barchman Wuytiers' predecessor, the Chapter notified the pope of the election of the archbishop-elect, requesting the pope's confirmation of the election and a dispensation for consecration by a single bishop. On August 23, 1725, Pope Benedict XIII issued a condemnation of the election of Barchman Wuytiers as Archbishop of Utrecht. The papal condemnation was even harsher than that of Barchman Wuytier's predecessor, Steenoven, suggesting that both Archbishop Steenoven and a priest named Theodore Doncker, who was present at Steenoven's consecration, died due to divine vengeance. Doncker, who was actually still alive, would later use the false statement of his death in the condemnation to argue against papal infallibility. On September 30, 1725, in the Church of St. James and St. Augustine in The Hague, Barchman Wuytiers was consecrated Archbishop of Utrecht by Bishop Dominique Marie Varlet. He received more than 100 letters of congratulation, signed by more than 2,000 ecclesiastics, including all the Roman Catholic bishops who had congratulated his predecessor, Steenoven.
Barchman Wuytiers sent word of his consecration to Pope Benedict XIII, who responded by excommunicating Barchman Wuytiers and all who assisted, encouraged and followed him. Barchman Wuytiers replied that he would offer to resign as Archbishop of Utrecht on the condition that Benedict XIII would recognize the rights of the Chapter of Utrecht and not force him and his priests to accept Unigenitus, the papal bull written in 1713 by Pope Clement XI condemning 101 purportedly Jansenist propositions.
Refuge for the Persecuted
Barchman Wuytiers received into his archdiocese clergy and religious who were persecuted in other places for their refusal to accept Unigenitus, including 31 Carthusian monks and 14 Cistercian monks from France. He attempted to form a mission to Indo-China by French missionaries who refused to accept Unigenitus.
The Chapter of Utrecht subsequently inquired of canonists in Louvain whether it had the right, as chapter of the metropolitan see, to appoint a vicar general for Haarlem, if the Chapter of Haarlem refused or delayed in doing so. With the assent of the canonists, the Chapter of Utrecht appointed Barchman Wuytiers as vicar general of the Diocese of Haarlem. He thus governed the parishes of the Diocese of Haarlem, both in his capacity as vicar general of the diocese and as metropolitan. Barchman Wuytiers was anxious to consecrate a bishop for the Diocese of Haarlem. After consulting Zeger Bernhard van Espen and others, he notified the Chapter at Haarlem that he would exercise his right as metropolitan to name a bishop, if they failed to elect their own candidate within three months. Three months passed, and Barchman Wuytiers assembled his chapter, which unanimously elected Theodore Doncker, who died before he was consecrated bishop of Haarlem.
Death
Archbishop Barchman Wuytiers died suddenly in his home at Rhynwyck, near Utrecht, on May 13, 1733.
