 A century later, in 1785, a clergyman with Unitarian ideas took his congregation and formed an independent Unitarian church.To this day, King's Chapel believes itself to be both a Unitarian church and an extramural Anglican church as it uniquely uses the "Book of Common Prayer According to the Use in King's Chapel" in its worship.In Canada, the first rupture with the incipient national church came in 1871, with the departure of the Dean of the Diocese of British Columbia, Edward Cridge, and many of the congregation of Christ Church Cathedral over the issue of ritualism.
