In this article, I review my recent book Protestant Modernity. Weber, Secularisation and Protestantism, which reconstructs Weber's theory of secularisation and argues that this is formulated within a liberal Protestant framework. I argue that this theory is a part of his Protestant account of modernity. I also sketch some of the major issues involved in developing a Catholic account of modernity and provide some worked through examples of the sociological implications of this change of confessional presuppositions.
