Critical Theory is a philosophy, or school of philosophy which goes back to the early decades of the 20th century. The Critical Theorists were frustrated that by the 1920s the hoped-for revolution had not materialized. This talk suggests that Critical Theory is a kind of alternative religion–complete with its own view of creation or metaphysics, its own understanding of sin, and its own understanding of redemption and eschatology. Indeed, Critical Theory is best understood as a vision of the world which is parasitic on Christianity. The Christian faith provides the better understanding of God, man, and the world–an understanding that Critical Theory cannot produce from its own commitments and insights.
