Anglo-Catholicism is the branch of the Church of England whose practices are closest to those of the Roman Catholic Church. Anglo-Catholic clergy may hear confessions and anoint the sick. It is sometimes referred to as 'High Church'.
It was promoted by the Oxford Movement (sometimes known as Tractarians) of the early Victorian period, whose leaders were John Keble, John Henry Newman and Edward Pusey. Newman, in fact, left the Church of England to join the Roman Catholic Church.
