The Method is a way to digest a potion. The Other must behave as prescribed by their stage until the power becomes part of them. Until the potion is digested, the bearer is vulnerable: the power is already there, but there is no control over it yet.
The roles of the path are service-oriented: the Sheriff maintains order and detains violators, the Investigator conducts inquiries and extracts the truth, the Judge makes decisions and is responsible for them.
The Method long remained the knowledge of a few: church hierarchies were in no hurry to reveal it, and many Others rose blindly, paying for it with their sanity.
