They included Catholics, Muslims, and Orthodox prisoners from Italy and other countries.
Among the lyrics the inmates sang while they danced were “Tonight you are not alone, Francis is there, everywhere. Hallelujah!” and “Pope is pop, our hope is pope.”
One inmate appears in the video saying: “This small world inside our prison, which also has many foreigners from various faiths, makes you realise that we are all equal.”
“The Pope has opened the doors of the Church, embracing the most diverse cultures, accepting and welcoming people from different religious faiths,” a Muslim prisoner who remained anonymous said in a statement released by Igor Nogarotto, who organised the event.
“He is showing us we can live in harmony under the same roof despite our diversity, really as we are living here today.”
Saying Francis was a “man of the people,” Mr Nogarotto said the initiative was a “multi-ethnic, secular prayer” to mark the end of the Pope’s Holy Year of Mercy.
