Pope Leo XIV called for greater global unity and denounced the harms of unchecked capitalism and power during his inaugural Mass in St Peter's Square before tens of thousands of people, including state guests, on Sunday. "In our time, we still experience too much discord, too many wounds caused by hatred, violence, prejudice, fear of others, and an economic model that exploits the Earth's resources and marginalizes the poorest," said the new pontiff at the Vatican.
