"The Foundations of Social Order was, and remains, the most unique book ever written in the history of Christendom. Nothing like it has been written before, and nothing like it has been written since. Christian and non-Christian historians have generally agreed on at least one thing about creeds and history: they are not connected in any meaningful, comprehensive way. A few non-Christian historians-Harold Berman and his Law and Revolution being a good example-have mentioned that the Christian creeds have been instrumental in shaping the legal views and therefore the legal structure of the West. But a general study of how the creeds formed the West and its unique outlook has always been lacking; the reason being that both Christian and non-Christian authors are eager to constrain the significance of the creeds to the church and the history of theology. Even Philip Schaff in his three-volume work, The Creeds of Christendom, confines their value and use to the church. The view of the creeds has been dualistic; creeds were separated from history, and history was left to follow its own course, independent from the development of Christian theology and the perfection of the faith of the saints.

"Rushdoony challenged that outlook, and he is the first author ever to create a systematic study of how the creeds of Christendom became the foundation for the worldview of Western civilization. Based on his Reformed faith, he clearly saw that ideas have consequences, and that the transformation of the pagan empire into the civilization of Christendom had its foundation in the formulation of what Christians believed about God, Jesus Christ, the Holy Spirit, about the two natures of Christ, the history and the nature of redemption, the church, etc. The creeds were not just for the church; they were the foundations of social order as we know it today, in every area of life. What we believe about politics-and therefore how we act in the political realm-will be determined by what we believe about the Trinity and the nature of redemption. What we believe about economics-and therefore how we act in the economic realm-will be determined by our beliefs about God, Jesus Christ, and His salvation. What we believe about any area of life, be it science, family, education, technologies, international relations, psychology, arts, etc.-and therefore how we act in all these areas of life-will be determined by our creeds. When Christianity set out to create a creedal culture, that creedal culture was not to be limited to the church and the personal faith of the individual. Anything not of faith was sin; and therefore everything had to be based on faith, and that faith had to be carefully formulated and communicated. Everything, including politics, and economics, and law: all life had to be based on faith, and therefore creeds mattered to all of life." - Bojidar Marinov
