The new music video sweeping the internet involves a group of sweet Polish nuns not praying, walking, ministering to the faithful, doing charitable work — or handling any other of their key duties and responsibilities.

No — in this video, the nuns are dancing for joy.

They’re welcoming all the young pilgrims traveling to Poland for World Youth Day, which is next week.

The group of nuns are from Mysliborz in West Pomerania, Poland. The sisters are part of St. Faustina’s order and they pulled off their own flash mob, according to Euronews.

The creative welcome to the thousands of young pilgrims even included a large picture of Jesus’ Divine Mercy.

Their exuberance and deep faith are absolutely contagious.

See their dancing skill below in living color:
