I am not sure about the meaning of the highlighted part of the following sentence:
A clear foe of the brute force deployed so unilaterally by the stupidly authoritarian Roman Empire, Getafix stands surety for another concept of order, based on much more humanist values.
Does that mean that he exchanges surety for another, better concept?
The dictionaries I've consulted don't feature this kind of construction.
Or is "surety" a spelling mistake and should be "surely"? I would have expected "firmly" then, though.
(EDIT: As I've commented below, I hadn't realised that "stand surety" is a phrase, otherwise I would have found it in a dictionary and not checked all the meanings of the entry for "stand").
