St. Peter's Church, Chantilly, is a primarily English-speaking Christian community made up of members of many different nationalities and denominations. It is part of the Church of England Diocese in Europe, which is a member of the worldwide Anglican Communion of churches.

After many years of financial support from the Intercontinental Church Society (ICS), up until the 1980s, St Peter's now relies entirely on the giving of its congregation to finance its resident chaplain and all the building running expenses, maintenance and upkeep.
