Pope Leo led Sunday (June 7) mass in Madrid's iconic Cibeles Square after driving past more than one million people who lined the streets to see him on the second day of his Spain tour.

Leo urged the crowds to live their Catholic faith by helping others in his sermon for the Mass.

The mass falls on the Catholic Corpus Christi feast day, or body of Christ, and the pope led a procession of the faithful around the square, also lined with hundreds of thousands of people hoping to catch a glimpse of him and walking on flower beds arranged along the route.

Cibeles Square, with its 18th century marble fountain and neo-classical architecture is also where people traditionally gather to celebrate Real Madrid football club's victories.

After Mass, Leo was scheduled to hold a private meeting with fellow members of his Augustinian religious order in the afternoon before meeting figures from the world of entertainment, sport and culture at a concert venue in central Madrid.

“It is not merely a matter of bringing out the monstrance, but of allowing ourselves to be brought out of our selfishness and indifference, of a comfortable, private faith, so as to respond to his invitation to conversion, to change our perspective, and to welcome his presence which transforms us and makes us builders of a new world.''

“Herein lies the task of Spain today and in the future: to ensure that the religiosity which has shaped and defined this country for centuries is not a museum of the past to be visited, but a school of faith from which to draw even today: A school that teaches us to kneel before God and before our neighbour, because no one can kneel before the Lord and despise their brother.''
