Catholics are normally seen as Christians who sing the Alleluia without smiling, keeping their arms firmly by their sides and pointed towards the floor at all times.
Under Pope Francis, this is changing. 

Last Saturday, along with around 60,000 charismatic worshippers, the Latin American pontiff stood in Rome’s Circus Maximus praying with his arms slightly outstretched, hands raised and eyes closed. In the crowd there was dancing, singing and speaking in tongues, and flanking him on either side were two female leaders of the Catholic Charismatic Renewal.
