"Anxious Angels" provides a comprehensive introduction to the religious currents of existentialism that gained significance in the 20th century. The book sheds light on the thought processes of prominent religious thinkers who often exist in the shadow of their atheistic counterparts. It argues that these thinkers represent an independent and relevant voice within existentialism that deserves attention even in today's postmodern era. Through a critical analysis of their ideas, the reader is invited to explore the complex connections between religion and existentialism and to understand their influence on modern thought. The author, G. Pattison, offers a nuanced perspective that takes into account both the philosophical and theological dimensions of this school of thought.
