By Naomi O'Leary VATICAN CITY (Reuters) – Pope Francis attacked unfettered capitalism as "a new tyranny" and beseeched global leaders to fight poverty and growing inequality, in a document on Tuesday setting out a platform for his papacy and calling for a renewal of the Catholic Church. The 84-page document, known as an apostolic exhortation, was the first major work he has authored alone as pope and makes official many views he has aired in sermons and remarks since he became the first non-European pontiff in 1,300 years in March. In it, Francis went further than previous comments criticizing the global economic system, attacking the "idolatry of money", and urged politicians to "attack the structural causes of inequality" and strive to provide work, healthcare and education to all citizens. "How can it be that it is not a news item when an elderly homeless person dies of exposure, but it is news when the stock market loses 2 points?" The pope said renewal of the Church could not be put off and said the Vatican and its entrenched hierarchy "also need to hear the call to pastoral conversion".
