Most Anglican crises, including recent ones, seem to boil down in the end to two linked questions — those of identity and authority. Is the Church of England pre-eminently a national or a catholic Church, a Protestant Church (and if so, of what kind?) or Anglican and sui generis? With which of these types of Church should it align itself? Where lies the famed via media, and which are the extremes to be avoided? And who has the authority to decide: as a national Church, parliament, the government, the monarch personally; as an episcopal Church, the bishops? Or should the clergy in convocations (or, latterly, the General Synod, including representatives of the pious laity) take decisions? Anglican crises have always raised these twin problems of identity and authority. In the mid-eighteenth century — from the end of the 1730s and particularly in the 1740s — the Church of England faced another crisis. The Anglican bishops had to come to terms with the movement known as the ‘evangelical revival’. Principles had to be applied to a new situation. The bishops had to decide how to categorise the new societies (or would they become new churches?) which were springing up all over England.
