This idea has looked more and more clear to me for some time: that communism and capitalism (understood along with its close parallel of consumerism) are the twin children of modern secular thought. I therefore was interested to find this thought so succinctly expressed by the Standing Conference of the Canonical Orthodox Bishops in the Americas from the year 2000:
As bishops who have ties to many churches that suffered terribly under communism we believe that we have an understanding of that system that few other Americans share. The common belief that communism was predicated on atheistic materialism is true. However, we acknowledge that our capitalist system is no less predicated on purely materialist principles, which also do not engender faith in God. There is no place in the calculus of our economics to account for the “intangibles” of human existence. Reflect on how the simple accounting phrase “the bottom line” has shaped our whole culture. We use it to force the summarization of an analysis devoid of any externals or irrelevancies to the “heart of the matter.” This usually means the monetary outcome.
