This book covers theoretical aspects of Catholic Religious Education in schools and examines them from multiple theoretical and contextual perspectives. It captures the contemporary academic and educational developments in the field of Religious Education while discussing in detail the challenges that Religious Educators face in different European, Asian, African, Australian, American and Latin American countries. The edited collection investigates how to pass on a Catholic heritage as a “living tradition” in diversely populated schools and communities. In this way it explores and asserts the proper identity of Catholic Religious Education in dialogue with Catechetics and with the wider discipline of Religious Education. As the different articles of this publication demonstrate - through a series of interesting and critical points of view - Catholic Religious Education is confronted with many challenges from the risk of marginalization to the confusion produced by a religious indifferentism leading to a strictly comparative or neutral method in the study of religions. It is essential to take into account in our research perspectives that Catholic Religious Education is not only a subject but also a mission in the light of the diakonia of truth in the midst of humanity H.E.
