"Religion inside and outside Traditional Institutions" combines conceptual reflection, methodological proposals, and research results that help to understand contemporary religious praxis. These contributions to empirical theology thereby adopt a perspective which includes religious praxis outside traditional institutions.

Heinz Streib (Ph.D., 1989, Emory University, Atlanta, U.S.A.; Habilitation, 1995, Johann-Wolfgang-Goethe-Universität, Frankfurt/M., Germany) is Professor for Religious Education and Ecumenical Theology at the Universität Bielefeld, Germany. One of his theoretical projects is faith development theory and method. His more recent empirical research has focussed on deconversion.
