Pope Francis has challenged the world's business elite to do more to help the poor and vulnerable.
In an address read by Cardinal Peter Turkson at the World Economic Forum in Davos, Switzerland, the leader of the world's 1.2 billion Catholics said it was intolerable that thousands die each day from hunger.
The pope urged leaders to adopt a new "political and business mentality" and to put their skills to work for the benefit of those living in dire poverty.
"I ask you to ensure humanity is served by wealth and not ruled by it," he said.
Since taking up his post in March 2013, Pope Francis has been outspoken about the problem of income equality, a central topic of this year's conference.
The papal address comes on the heels of an Oxfam report that found the world's 85 richest people now own as much wealth as the poorest 50% of the population.
Pope Francis said tackling inequality would require action to achieve a better distribution of wealth.
