The idea is not new. East Block countries (where religions were in disgrace) were creating various organizations. With the ideal of brotherhood, common ideology and their rituals (think about the International Workers' Day March). In any case, I do not share author's optimism. Believing in supernatural is not that bad; what is bad is we-vs-them mentality, fanaticism (you don't need a religion, but an ideology); and rituals, while comforting, tend to froze progress.
