The logo of the Holy Father’s apostolic trip – on the left hand side of the Holy See homepage – consists of a cross in the centre, representing Christ, the fulcrum of World Youth Day, from which there emerge two flames, red and blue, suggesting the rays of Divine Mercy, the blood and water that spring from Jesus’ rib, as in the image St. Faustina Kowalska was commanded to paint. The rays merge with the arm of a young person who embraces the cross. The logo has the shape of Poland, and the head of the young person corresponds to the geographical position of Krakow, while blue, red and yellow are the official colours of the city. The theme of this year’s World Youth Day is a phrase from the Gospel of St. Matthew: “Blessed are the merciful for they shall receive mercy”.
