The book includes a continuation of Part III “Religious and Ideological Systems”, consisting of sections 3.3.3 The religious system of historical Islam and the culture of the Koran” and 3.3.4 “Freemasonry and Marxism”. The fourth book ends with a separate section, “Theology of Russian Civilization.” The chapter on the religious system of historical Islam ends the cycle of consideration of the three main “world” religious systems (Judaism, Biblical Christianity and historical Islam), considered “Abrahamic,” and their interrelations. The next chapter, “Freemasonry and Marxism,” continues the theme of the biblical concept from the position of the expediency of the global scenario. And finally, the last chapter of the fourth book is a look at some basic aspects of Russian theology.

This section of the Study Guide is not included in the scope of the third chapter and therefore is not numbered.
