The citation noted his "particular gallantry and zeal during the operations from Medevja-gora to Unitsa, 8 June to 26 July 1919". Church first stood for Parliament at the 1922 general election, when he was unsuccessful in the Conservative safe seat of Spelthorne. After five years out of Parliament, he took Wandsworth Central at the 1929 general election from the Conservatives with a majority of only 300 votes (11% of the total).
In July 1931, Church introduced to the House of Commons a Ten Minute Rule Bill promoted by the Eugenics Education Society.
Although the eugenics measure was "a Bill to enable mental defectives to undergo sterilizing operations or sterilizing treatment upon their own application, or that of their spouses or parents or guardians," its underlying purpose was the eventual introduction of compulsory sterilisation as well, with Church describing it as "an experiment on a small scale so that later on we may have the benefit of the results and experience gained in order to come to conclusions before bringing in a Bill for the compulsory sterilisation of the unfit." The Commons voted by 167 votes to 89 to deny the Bill a second reading. He followed MacDonald into the new National Labour Organisation, but did not stand again in Wandsworth at the 1931 general election.
Instead he stood as a National Independent in the London University constituency, where he came second of two candidates, with only 27% of the votes. He stood again twice, as a National Labour candidate in Bristol East at the 1935 general election and in Derby at a by-election in July 1936, and in Tottenham South as a National candidate at the 1945 general election but never returned to Parliament.
