This study will look at how middle age philosophy or Christian pop-culture impacted its world. While the Christian Church is significantly addressed in middle ages study, the central theme of what the Church taught is often understated as to its impact. Pieces of evidence reflect that medieval philosophy was dictated by theological teachings of sin and salvation. It was St. Augustine of Hippo, who was a key influence in the development of this Christian world view. The concepts were prevalent in the way society thought, acted, as well as performed funeral customs. It was also evident in the many frescos of the period. This philosophy’s importance is a key aspect to grasping the middle age successes and downfalls while continues as a part of modern history. It was of fundamental historical importance that Augustine laid a philosophical foundation of sin and salvation in the Medieval Period, that gave hope to a dark world and mission to carry out; that nevertheless, subsequently, history substantiated the hypothesis by revealing the corruption of the very institution that sought to absolve the concepts’ reality. Sin and salvation theology is essentially the medieval philosophy that shaped how people thought, lived and died in the middle ages.
