There is already a congregation of Huguenots meeting in Westminster. King Charles the Second agrees to make its existence official, but only on condition that its members change the way they worship. They must use a French translation of the Church of England prayer book. The new church holds its services in the Little Chapel in the Savoy Hospital.
There are now two different sorts of Huguenot church in London. The Savoy church is conformist: it conforms to the Church of England and uses the Anglican prayer book. The original French Church in Threadneedle Street is a nonconformist church. It continues to use the Calvinist form of worship that the first refugees brought from France, more than a hundred years earlier.
