"Let us not fail, young comrades; let us not write on the scroll of history that mankind had to go through yet new generations of wars and tumults and enslavements, because the youth of the international revolution could not lift themselves above those ancient personal vices which wrecked the fair hopes of their fathers—bigotry and intolerance, vindictiveness and vanity, envy, hatred and malice and all uncharitableness!"
I swear I didn't start reading this book to perfectly coincide with the latest battle between Church and State i.e. the Kim Davis controversy. It just so happened that it was the final book in my stack of "religion is dumb lol" books I had horded from when I worked at a bookstore. It just so happens that conflicts between religious belief and public policy is as old as... well, history as we know it. Frankly, I was surprised this even existed - the idea of such a harsh indictment of religion, especially Christianity (but specifically Catholicism), being published in 1918 seems unfathomable to me. However, here it stands and it's quite a ballsy critique/expose, which shouldn't be entirely surprising from the man who wrote The Jungle.
The book doesn't solely focus on religion, as Sinclair also takes time to make it clear that big business is the main source of corruption in religion. I definitely think there is something to be said for that too, especially when you take stock of the "mega churches" that pockmark the American landscape, which seem more like temples devoted to Capitalist demagoguery than anything Jesus would have considered appropriate to his core teachings.
This book is a nice read though, and certainly belongs in the pantheon of must-read religious critiques, along with Bertrand Russell's "Why I am Not a Christian" and Sam Harris's "The End of Faith"
