“We seek, and have, the support of the Church in what we do. At the head of the pilgrimage we carry La virgen de la Guadalupe because she is ours, all ours, Patroness of the Mexican people. We also carry the Sacred Cross and the Star of David because we are not sectarians, and because we ask the help and prayers of all religions.”

Context: And finally, let's remember that our leadership is defined not just by our defense against threats but by the enormous opportunities to do good and promote understanding around the globe, to forge greater cooperation, to expand new markets, to free people from fear and want. And no one is better positioned to take advantage of those opportunities than America. Our alliance with Europe remains the strongest the world has ever known. From Tunisia to Burma, we're supporting those who are willing to do the hard work of building democracy. In Ukraine, we stand for the principle that all people have the right to express themselves freely and peacefully and to have a say in their country's future. [... ] We do these things because they help promote our long-term security.
