He was assistant curate of Brighouse (1940โ42) before entering the Royal Naval Volunteer Reserve as a chaplain and serving in the Far East. In 1946 he was appointed chaplain of Cuddesdon College and he was briefly a member of the Oratory of the Good Shepherd. He spent the period 1949-52 as chaplain of St John's College, Cambridge (Cambridge MA 1949) and then he returned to Cuddesdon as principal from 1952 until 1960.(Johnson 2013, p. 174) He was noted for his imposition of a strictly disciplined lifestyle on his students. He particularly emphasised the 'custody of time'(Tustin 2013, p. 87) Later on Knapp-Fisher found that the 'custody of time' needed to be interpreted differently in South Africa.[1] As well as being the principal of the theological college at Cuddesdon he was also vicar of the Church of All Saints, Cuddesdon and he served as rural dean 1958โ60.
