St. Mary's Church and St John's, Churchill form one Parish of the Locking Deanery in the Diocese of Bath & Wells. The adult population of Langford according to the Register of Electors of 1999 comprises 1214 adults in approximately 584 dwellings. Practically all live within less than 3/4 of a mile of St. Mary's Church, the majority being in the area bounded by Bridgwater Road, Ladymead Lane, Pudding Pie Lane and Stock Lane.
Families very much dominate the population scene. Additionally there is some local authority housing for elderly in St. Mary's Gardens very close to the Church and also a significant population of Vet students and others associated with Langford House, some of whom live on the campus and others in the surrounding villages.

Relations between the Church and Churchill Primary School are good and Church work with children of Primary School age is probably among the healthiest within North Somerset. Other places of worship comprise an Independent Evangelical Chapel, and Churchill Methodist Church. The nearest Catholic Church is in Cheddar.
