Members of the Church of England are part of an ordered Church with a given liturgy. That order is deeply embedded in our story and today all clergy and lay ministers function and carry out their ministries on the authorisation of the bishop of the diocese. The Church of England is an institution which has its rules, laws and codes of conduct. Because we have no doctrinal formulations of our own, the liturgy in the Church of England expresses much of our theology. While there have been many changes in liturgy, a given liturgy, or a liturgical structure within which certain texts are prescribed, is part of how we are.
