While I visited the Popes home in the Vatican city he decided to visit the US. During his visit, Pope Benedict XVI gave a consistent and prophetic call to U.S. Catholics that might have something to say to humans everywhere:

I want to encourage you and your communities to continue to welcome the immigrants who join your ranks today, to share their joys and hopes, to support them in their sorrow and trials, and to help them flourish in their new home. This, indeed, is what your fellow countrymen have done for generations. From the beginning, they have opened their doors to the tired, the poor, the “huddled masses yearning to breathe free.” These are the people whom America has made her own.
