The purpose of the Cambridge Edition is to offer translations of the best modern German edition of Kant's work in a uniform format suitable for Kant scholars. When complete (fourteen volumes are currently envisaged), the edition will include all of Kant's published writings and a generous selection of his unpublished writings such as the Opus postumum, handschriftliche Nachlass, lectures, and correspondence.

This volume collects for the first time in a single volume all of Kant's writings on religion and rational theology. These works were written during a period of conflict between Kant and the Prussian authorities over his religious teachings. His final statement on religion was made after the death of King Frederick William II in 1797. The historical context and progression of this conflict are charted in the general introduction to the volume and in the translators' introductions to particular texts.

All the translations are new with the exception of The Conflict of the Faculties, where the translation has been revised and re-edited to conform to the guidelines of the Cambridge Edition. As is standard with all volumes in this edition, there are copious linguistic and explanatory notes, and a glossary of key terms.
