Six-year-old Renzo Pons Mendoza, born in Buenos Aires and living in Barcelona for over three years with his family, experienced an unforgettable moment during Pope Leo XIV's visit to Catalonia. In front of the Pontiff, at the Sant Agustí church in the heart of Barcelona's Raval, Renzo read a letter he had previously sent, evoking great emotion and applause from those present.

This moving exchange was one of the highlights of the papal visit. Renzo, accompanied by his mother, shared his questions and reflections with the Pope, who responded with gestures of complicity and emotion. The story of this boy and his letter originated from an initiative by the Diocese of Barcelona to create a unique event during the Pontiff's visit to his favorite church.

The idea was carried out by Joan Costa, in charge of the parish visit, and parish priest Ferran Lorda, with the collaboration of the production company Daristoteles, directed by David Hernández. A video titled ‘Abre la carta’ (Open the letter) was created and shown before Renzo read the message in person.

Renzo, a football enthusiast and admirer of players like Leo Messi and Lamine Yamal, expressed his concerns about topics such as his parents' worries, his father's multiple jobs, injustices, poverty, the loneliness of the elderly, and the importance of forgiveness. The Pope answered all his questions, sharing childhood anecdotes and reflecting on faith and forgiveness.

Renzo's mother, Sandra, highlighted her son's sweet nature and the significance of this moment for the entire family, who came to Barcelona from Buenos Aires seeking a better future. The initiative had the approval of the Vatican.
