Upon graduating theological college, Bateman-Champain was made deacon at Advent 1903[6] and ordained priest the following Advent (18 December 1904) — both times by George Forrest Browne, Bishop of Bristol, at Bristol Cathedral.[7] He served his title as assistant curate of St Mary Redcliffe, Bristol until 1908;[1] from 1904 onwards, John Maud (his future father-in-law) was Vicar of St Mary Redcliffe.[8] His first post was overseas (South Africa) as vicar of Krugersdorp and St Boniface Church, Germiston.[9] On the Feast of the Ascension (16 May) 1912, he was instituted Vicar of St Mary Redcliffe.[10] During the Great War he was interviewed for a commission with the Army Chaplains' Department, and was described as an 'attractive personality A1'. He was sent to the Western Front and, from 1918, served at General Headquarters.[11]
Bateman-Champain was part of a large cricketing family. His brothers Claude, Francis and Hugh all played first-class cricket, as did his brother-in-law Frederick Currie. His uncles Fendall Currie, Revd Sir Frederick Currie, Robert Currie and William Currie also played first-class cricket.
During his second time at Redcliffe, he married in 1912, Jean Monsell Maud, eldest daughter[1] of John Maud, previously Vicar there (while Bateman-Chapmain was Curate)[8] but by then Bishop of Kensington; they had two sons and two daughters.[1] One son was killed on active service in 1943.[17] Bateman-Champain died at Westbury-on-Trym on 22 October 1950.
