this temporal advantage that the Pope is obtaining for the Mortara boy?

Does "this temporal advantage that the Pope is obtaining for the Mortara boy" refer to "because of the Mortara boy, the Pope is getting the advantage for the time being"?

Context:

Whoever among us gives a little serious thought to the matter, compares the condition of a Jew - without a true Church, without a King, and without a country, dispersed and always a foreigner wherever he lives on the face of the earth, and moreover, infamous for the ugly stain with which the killers of Christ are marked . . . will immediately understand how great is this temporal advantage that the Pope is obtaining for the Mortara boy.
