"Opium of the People" - this phrase is familiar to us all. But who truly knows the religiously critical texts of Karl Marx? Bruno Kern first introduces the original texts of Marx and offers a thorough examination of this radical questioning of religion. In doing so, he clears away many popular misunderstandings and provides an account of "our hope" in conversation with Marx. Bruno Kern demonstrates how Marx should be rethought in the 21st century: a new reading of his texts from our present perspective has immediate consequences for the debate about religion, the debate about God. This creates a completely new basis for dialogue between politically engaged believers and non-believers. This book aims to inspire that conversation.
