On 24 April 2011, Waller officially converted from Anglicanism to the Roman Catholic Church.[5] He was ordained as Catholic deacon on 14 May 2011 and as a priest on 11 June 2011, both times by Thomas McMahon, Bishop of Brentwood.[5] He was parochial administrator of St John the Baptist church, Ilford, from 2011 to 2015, and then parish priest of Christ the King, Chingford, from 2015 to 2024.[1] In 2020, he was additionally appointed vicar general of the Personal Ordinariate of Our Lady of Walsingham by its ordinary, Keith Newton.[6]
Episcopal ministry
On 29 April 2024, it was announced that Pope Francis had appointed Waller as the next ordinary of the Personal Ordinariate of Our Lady of Walsingham.[7] He is celibate and was therefore consecrated as the first bishop-ordinary of Our Lady of Walsingham; his predecessor Newton was married and therefore ineligible for the episcopate.[8][9]
On 2 July 2024, Waller undertook his first ordination; that of Richard Pain, a former Anglican bishop, to the diaconate.[15] He then undertook his first ordinations to the priesthood of four men including Pain, on 20 July.[16][17]
