Ranald the Protector is an Idealist who despises everything the Empire stands for, and will not hesitate to acts of extremism to overthrow it.
Honestly, it can actually be argued that worshipping Ranald is a violation of the Articles:
Ranald the Protecter is in direct opposition to the "Ideals and Laws of Sigmar's Holy Empire". By worshipping Him, by obeying His commandments, and by heeding His lessons, we are in direct violation of the First Article, because Ranald teaches us that the Ideals and Laws of the Empire are illegitimate, and the Articles commands us to uphold those Ideals and Laws as sacred.
We can not be loyal to both—To be a Ranaldian is to betray the Empire, and to be a Magister is to betray Ranald.
And yet, we are, because we are a Grey Wizard, and dancing on the line between two extremes is literally the the metaphor our soul is made out of.
Also because the Deciever thinks it's the funniest thing He's ever seen. She turned herself into a living contradiction.
