Smelly Little Orthodoxies
Orwell thought all abstract doctrines misled the local people from correcting obvious wrongs based on their own perceptions or common sense. Orwell referred to socialist, capitalist, Christian (ironically, especially Catholic) and other doctrines as "smelly little orthodoxies."
In the most recent issue of First Things, Paul J. Griffiths in an article titled "Orwell for Christians" points out the many things Christias can learn from Orwell.
Importantly, Griffiths points out how closely Orwell's suspicion of smelly little orthodoxies echoes that of the Roman Catholic Church. From Leo XIII's Rerum Nevorum to John Paul II's Centismus Annus, the Popes have insisted in not identifying a single political or economic doctrine to answer social questions, but instead has concentrated on identifying instances of offense against natural law and natural rights which are associated with certain political or economic doctrines.
In my opinion, Orwell and the Roman Catholic church (at its best) share similar approaches to Big Brother.
