St. Augustine of Hippo 
On the Destruction of the City [EPUB ebook] 

In this short work, attributed to St. Augustine of Hippo (although likely a 15th century work), the example of Daniel’s confession of sins is discussed, emphasizing the importance of humility and recognition of sinfulness, even among the bionically righteous. The analogy is drawn between the biblical example and the sinfulness of other great contemporary cities.
