The Sanctuary of the Angels Church has repeatedly been a target of vandalism.
The man was later hospitalized while the statue was returned to the church, apparently undamaged by the incident.
The vandals asked local authorities for "ransom" money.
The police seized the car and recovered the stolen items.
In January, two other religious buildings were broken into and desecrated in the Seine-Saint-Denis department.
The thief was arrested on the spot and taken to the responsible police station for further inquiries.
The series of thefts in Tuscany has been ongoing for the past few weeks.
