The son of a pastor of the
Dutch Reformed Church, Wallet converted to
Old Catholicism and completed his theological studies at the
University of Hull in 2005 and from the Old Catholic Seminary in
Amersfoort in 2006. He was ordained a deacon in 2006 by Archbishop
John Sentamu of the
Anglican Diocese of York. One year later, he was ordained a priest by Archbishop
Joris Vercammen at
St. Gertrude Cathedral in
Utrecht. From 2007 to 2010, Wallet served as assistant curate in
Northallerton, in the Diocese of York (
Church of England). On his return to the Netherlands, he served as personal assistant to Archbishop Vercammen, responsible for external relations with other Old Catholic churches of the
Union of Utrecht as well the
Anglican Communion. Wallet served as pastor of St. Gertrude Cathedral in Utrecht from 2015 to 2020. On 15 February 2020, he was elected
Archbishop of Utrecht by the cathedral chapter of Utrecht. At that time, he said, "I want to challenge our parishes to be open houses for those in their areas ... We must continue to be open to society and testify with joy to the hope that is in us." Wallet's episcopal consecration was first scheduled for 21 June, but was postponed because of the
COVID-19 pandemic. On 23 October 2020, the metropolitan chapter of Utrecht announced that the consecration, which had been scheduled for 7 November 2020 (the Feast of St
Willibrord, the first bishop of Utrecht), had to be cancelled a second time. He was eventually consecrated as a bishop on 18 September 2021 at the
Lebuïnuskerk in
Deventer by Old Catholic bishop Dirk Schoon, with bishops
Matthias Ring (
Catholic Diocese of the Old-Catholics in Germany) and
Robert Innes (
Church of England) acting as co-consecrators; other bishops of the Church of England, the
Episcopal Church, and the
Church of Sweden also took part, while the
Catholic Church, the
Protestant Church of the Netherlands and the
Ecumenical Patriarchate of Constantinople sent some delegates without taking part in the ceremony. He was enthroned on the following day in
St. Gertrude's Cathedral in
Utrecht. ==References==
