This work is an analysis of the causes of the decline of religious faith in British society through the birth and emergence of new doctrines and concepts such as capitalism, the Enlightenment, science and reason. As indicated throughout this work, the emergence of new philosophies must be considered as the main causes of the decline of religion in British society because it has encouraged British society questioning things that were never questioned before. Today, with the emergence of the religious faith crisis in the United Kingdom, many questions arise about its causes and its consequences. On the basis of these changing realities in the area of religious faith and practice, this article is very important because it tries to underline the doctrinal causes of this phenomenon. To conduct this work we decided to adopt two different methodological approaches: a descriptive approach and an analytical approach which allowed us to present and analyze the two different parts. The descriptive approach allows us to describe how the birth of new doctrines is impacting religion in British society and an analytical approach which is a particular type of research and involves critical thinking and evaluation of facts and information emanating from this phenomenon.
