Church not a museum?  Why then in the  museum business?
Money stream!  Francis can yap on but as long as it clings to investing YUGE resources of personnel, etc. Vatican is primarily a museum.
Imagine follow-up to Francis' assertion, headlines in L'Osservatore Romano: Francis to divest Vatican museums, return stolen property, inappropriate gifts, resources to pay off pedophile claims and daily bread for the poor.  Now that's evangelization!
Facta, non verba!
