On Sunday, Pope Leo XIV celebrated a Mass in Madrid attended by hundreds of thousands, emphasizing the significance of flower carpets, a hallmark of Spanish popular piety, during the Catholic Corpus Domini feast. The procession featured 16 elaborate flower carpets, crafted by a florists association from Galicia, using over 30,000 flowers, predominantly in the colors of the Holy See flag. The event aimed to inspire youth engagement in faith, as demonstrated by the attendance of approximately 600,000 young Spaniards at a vigil service the previous night, where they knelt in silent prayer alongside the Pope. Leo urged the crowd not to shy away from considering vocations in the church. This tradition of flower carpets, which dates back two centuries, also holds cultural significance in Latin America and is being pursued for recognition as part of the world’s intangible cultural heritage. Later, the Pope is scheduled to meet with members of his Augustinian order and cultural leaders, promoting unity in a polarized society.
