Conclusion—Periodizing Secularization
Since most chapters contain individual summaries, they are not reproduced in the conclusion. Rather, there is a holistic overview of religious allegiance and churchgoing across seven micro-periods between 1880 and 1980, with reference to a hybrid measure of adult ‘active church adherence’ relative to population. This declined continuously and gradually, undermining arguments for ‘revolutionary’ secularization in the 1960s. A second section considers six dimensions of ‘diffusive religion’, a basket of alternative performance indicators cited by some scholars who contend religion has not declined but simply changed, moving away from institutional expressions. Such claims are not judged evidentially strong. The third section updates secularization’s historiography, critiquing previous work on the alleged religious crisis of 1890–1914, the religious impact of the world wars, and the so-called religious revival of the 1950s and crisis of the 1960s. The causation of secularization is discussed, and weakening Sabbatarianism and religious socialization of children are emphasized.
