The Orzhov Syndicate may cloak themselves in a veneer of religion, but it's all a sham. This false piety is only a smokescreen, and a means of control. Their real business is business: there's no financial dealing or trade that the Orzhov do not know about, if not outright manipulate. The Ghost Council, made up of the immortal spirits of past Orzhov leaders, make sure that nothing stands in the way of the Syndicate ruling Ravnica through gold and greed.
Now compare that to
The Protocols of the Learned Elders of Zion.
