Anglicanism most commonly refers to the beliefs and practices of the Anglican Communion, a world-wide affiliation of Christian Churches, most of which have historical connections with the Church of England .
Leon Bertoletti, in "Anglicanism" at Hic Sunt Leones (24 June 2008)
The concept of our established Church is occasionally misunderstood and, I believe, commonly under-appreciated. Its role is not to defend Anglicanism to the exclusion of other religions. Instead, the Church has a duty to protect the free practice of allfaiths in this country.
The Church of England depends, for its existence, almost entirely on the solidarity and conservatism of the English ruling class. Its strength is not in anything supernatural, but in the strong social and racial instincts which bind the members of this caste together; and the English cling to their Church the way they cling to their King and to their old schools: because of a big, vague, sweet complex of subjective dispositions regarding the English countryside, old castles and cottages, games of cricket in the long summer afternoons, tea-parties on the Thames, croquet, roast-beef, pipe-smoking, the Christmas panto, Punch and the London Times and all those other things the mere thought of which produces a kind of warm and inexpressible ache in the English heart.
Perhaps one explanation of the sterility and inefficacy of Anglicanism in the moral order is, besides its lack of vital contact with the Mystical Body of the True Church, the social injustice and the class oppression on which it is based: for, since it is mostly a class religion, it contracts the guilt of the class from which it is inseparable.
