Pope Francis greets the crowd as he arrives for his general audience at St Peter's square on November 27, 2013 at the Vatican.
Pope Francis has spent less than a year as head of the Catholic Church, but in that time a series of his pronouncements have gained a lot of attention.
He's offered welcoming words to atheists, for example. Regarding gays, he said, "Who am I to judge them? They shouldn't be marginalized." Now, in a major statement issued yesterday, he has the world — Catholic and non-Catholic — buzzing again:
"Just as the commandment 'Thou shalt not kill' sets a clear limit in order to safeguard the value of human life, today we also have to say 'thou shalt not' to an economy of exclusion and inequality. Such an economy kills."
For a look at what this signals about the future direction and philosophy of the Catholic Church, we're joined by Christopher Kaczor, professor of philosophy at Loyola Marymount University.
