St Peter's, Calow is a Victorian (Grade II listed) church prominently situated immediately to the east of Chesterfield on the main road to Bolsover. It is usually open on Sundays from 9.00am until 11.30pm, often for longer, and on other days as well. It serves a community of around 3,000 people and is part of a united benefice which includes St Mary's, Sutton Scarsdale . On the first Wednesday there is a coffee morning from 1030-12 and on the third Wednesday a parish lunch from 12-1330
St Peter's has always been in the catholic tradition, and the PCC requested that alternative episcopal oversight be granted by The Bishop of Derby . The parish is now under the pastoral care of The Bishop of Ebbsfleet. The ethos is best described as Anglo Catholic. Vestments, incense and bells are used at the 10am Sung Eucharist and the blessed sacrament is perpetually reserved, Common Worship Order 1 usually is used, traditional hymns predominate .
Between a quarter and a third of the regular congregation live outside the parish, but the majority of those are former residents. Patients and staff from the nearby Royal Hospital bring variety to the congregation from time to time.
A Parish Safeguarding Officer is in place covering the whole benefice and the parish uses the Derby Diocesan standard provision for the care of vulnerable people.
