Third Vicar of St Jude's church, he served for nearly 20 years from 1936-1954 when he sadly died in office. Under his time as Vicar the Church's organ was moved to its current position and Charles Proctor (who became Rosemary Rennie's husband) a composer and conductor, became the organist.
Rennie also introduced voices from the laity speaking, which included such prominent figures as C S Lewis.
