Pope Leo in Sagrada Familia, Barcelona It is faith that shapes the stones and gives meaning to the edifice we inhabit together. In our prayer, therefore, we discover the original bond between all things and God, the Creator of heaven and earth. He is the Artist who has imprinted his splendour upon the cosmos. Created in his image, humanity responds to God’s work with its own ingenuity: this is how the artist transforms talent into praise and creativity into a testimony to the Creator himself. As an architect inspired by faith, the venerable Antoni Gaudí designed this place with the desire to narrate the mysteries of the Lord’s life. In this way, he has proposed to us a spiritual pilgrimage, leading to an encounter with Christ who for our sake was born, died and rose again. Together with Gaudí, as we commemorate the centenary of his death, we remember and give thanks this evening to all the supporters and benefactors, the artists and the workers who cooperated in the construction of an architectural masterpiece, which is also an eloquent catechesis made of stones, colours and light. In her wisdom, the Church thus renews the Biblia pauperum of the ancient cathedrals, which are in themselves rich messages of evangelization. In this age in which image is so prevalent, it becomes even more evident how art and beauty are privileged channels of evangelization.
