Aim of revolution, in France? Goodness! (2,3)

I believe the answer is:

ma foi

I'm a little stuck... Click here to teach me more about this clue!

'france? goodness' is the definition.
I don't know anything about this answer so I cannot judge whether it can be defined by this definition.

'aim of revolution' is the wordplay.
'revolution' is an anagram indicator.
'aim'+'of'='aimof'
'aimof' with letters rearranged gives 'MA FOI'.

'in' is the link.

Can you help me to learn more?

(Another definition for ma foi that I've seen is " my goodness!".)

I've seen this clue in The Globe and Mail.
