 The church regards itself as the continuation of the Catholic church introduced by St Augustine's 6th-century mission to Kent, although this is disputed owing to procedural and doctrinal changes introduced by the 16th-century English Reformation, particularly the Thirty-Nine Articles of Religion and the Book of Common Prayer.In 2010, the Church of England counted 25 million baptised members out of the 41 million Christians in Great Britain's population of about 60 million; around the same time, it also claimed to baptise one in eight newborn children.Generally, anyone in England may marry or be buried at their local parish church, whether or not they have been baptised in the church.
