Dr Mark Clavier has been installed as Residentiary Canon at Brecon Cathedral.

Archbishop John also licensed Rev Richard Allen as chaplain of Christ College, during the service at the cathedral on Sunday.

Canon Mark, who is originally from South Carolina, spent 13 years serving parishes in Maryland and North Carolina before moving to Britain nearly nine years ago.

While researching the idea of delight for his PhD, he served for three years as a “house for duty priest” in former mining villages in County Durham and subsequently two years as priest-in-charge of three churches at Steeple Aston, North Aston and Tackley in the diocese of Oxford.

In 2012, he moved to Cardiff to become the dean of residential training at the former St Michael’s Theological College, where he was responsible for overseeing the formation of future stipendiary clergy for the Church in Wales.

Between 2014 and 2016, he also served as the acting principal during St Michael’s transition towards becoming St Padarn’s Institute. Afterwards, he returned to Oxford to be the vice principal and director of pastoral studies at St Stephen’s House.

Mark has a 17-year-old son named Paul and was got married earlier this month to Sarah, who grew up in north Wales and has a doctorate in 17th-century Welsh history. They have two spaniels named Cuthbert and Humphrey.

Mark is an avid outdoorsman and has trekked in Norway and Iceland and has also spent countless hours exploring the Beacons.

Dean of Brecon Cathedral, the Very Rev Dr Paul Shackerley, said Mark “will bring an infectious enthusiasm, human pastoral warmth and clear theological insights to Brecon Cathedral and to the Diocese of Swansea and Brecon”.

“Mark’s gifts in teaching will help the people of God grow in faith, and encourage us all in our journey to become more Christ-like and faithful disciples,” he said. “I know that he will be warmly welcomed in Brecon and the diocese.”
