Pope Francis has wrapped up a historic trip to Mongolia to visit the minuscule Catholic community, in a visit that was also notable for his overtures to neighbouring China over freedom of religion. Francis ended his five-day visit with a stop to inaugurate the House of Mercy, a multi-purpose structure to provide temporary health care to the most needy in the Mongolian capital as well as to the homeless, victims of domestic abuse and migrants. Situated in a converted school and the brainchild of Mongolia's top Catholic cleric, Italian Cardinal Giorgio Marengo, the House of Mercy is destined to serve as a sort of central charity co-ordinating the work of Catholic missionary institutions and local volunteers. "The true progress of a nation is not gauged by economic wealth, much less by investment in the illusory power of armaments, but by its ability to provide for the health, education and integral development of its people," Francis said at the house on Monday. He said he wanted to dispel "the myth" that the aim of Catholic institutions was to convert people to the religion "as if caring for others were a way of enticing people to 'join up'". Mostly Buddhist Mongolia has only 1450 Catholics in a population of 3.3 million and in an unprecedented event on Sunday, just about the entire Catholic population of the country was under the same roof with the Pope. Mongolia was part of China until 1921 and the Pope's trip was dotted by allusions or appeals to the superpower next door, where the Vatican has scratchy relations with the communist government. At the end of Sunday's mass he sent greetings to China, calling its citizens a "noble" people and asking Catholics in China to be "good Christians and good citizens". On Saturday, in words that appeared to be aimed at China rather than Mongolia, Francis said governments have nothing to fear from the Catholic Church because it has no political agenda.
