As Mark McGinnes said, indeed, the new Pope is a breath of fresh air!
Catholicism has a mixed legacy as you would expect from a church that hopes to be all inclusive, but the recent change in the leadership of the Roman Catholic Church (RCC) bodes well for the poor and the planet. Pope Francis has made both the poor and the environment real priorities. In the past there have been many priests and entire orders within the RCC that labor for the poor and advocate for the environment. After all it is the poor who suffer the most from climate chaos. Until recently they had only tepid support from the Vatican.
One priest who worked for the poor was Father Oscar Romero. He was performing a Mass when he was gunned down for his opposition to the killing of the poor in El Salvador. Thanks to Pope Francis he is now on the path to well-earned sainthood.
