From 1995 to 1998 Newton was Rural Dean of Brislington. From 1998 to 2001 he was area dean of the new deanery of Bristol South. On 7 March 2002, Newton was consecrated as an Anglican bishop by George Carey, who was then Archbishop of Canterbury. Newton was subsequently named Bishop of Richborough and provincial episcopal visitor for the Province of Canterbury in 2002. He held this post until 31 December 2010.
Ordination in the Roman Catholic Church
In 2008 Newton met officials of the Congregation for the Doctrine of the Faith to discuss the possibility of joining the Roman Catholic Church. On 8 November 2010, Newton announced his intention to leave the Church of England at the end of the year in order to join the proposed personal ordinariate of the Roman Catholic Church for former Anglicans. Newton was received into the Roman Catholic Church on 1 January 2011, at Westminster Cathedral, with his wife Gill, by Bishop Alan Hopes. Also received at the same ceremony were Andrew Burnham, John Broadhurst and his wife Judith, and three former sisters of the Society of St Margaret – Sister Carolyne Joseph, Sister Jane Louise and Sister Wendy Renate. On 13 January 2011 he was ordained to the diaconate with the two other former Church of England bishops, Andrew Burnham and John Broadhurst. Two days later, on 15 January 2011, they were ordained to the priesthood by Vincent Nichols, Archbishop of Westminster, in Westminster Cathedral. On this date Pope Benedict XVI appointed Newton the first ordinary of the Personal Ordinariate of Our Lady of Walsingham in England and Wales. According to its teachings, the Catholic Church will not permit his consecration as a Bishop, because he is married. On 17 March 2011, it was announced that Pope Benedict XVI had granted Newton the title of protonotary apostolic. Although Newton, as ordinary, does not have an episcopal ministry, he has been granted the use of pontificals by the Holy See in the same manner as some abbots. Newton became a cruise chaplain with seafarers' welfare charity Apostleship of the Sea in 2014.
Personal life
Newton is married to Gill, a teacher, with whom he has three adult children – Lucy, Tom and James.
