Burke's religious writing comprises published works and commentary on the subject of religion. Burke's religious thought was grounded in the belief that religion is the foundation of civil society. He sharply criticised deism and atheism, and emphasised Christianity as a vehicle of social progress. Born in Ireland to a Catholic mother and a Protestant father, Burke vigorously defended the Anglican Church, but also demonstrated sensitivity to Catholic concerns. He linked the conservation of a state (established) religion with the preservation of citizens' constitutional liberties and highlighted Christianity's benefit not only to the believer's soul, but also to political arrangements.
