Pope Francis warned against the abandonment and neglect of the elderly, calling it a "hidden euthanasia" rooted in today's "poisonous" culture of disposal and an economic system of greed.
In the presence of his predecessor, Pope Francis also thanked retired Pope Benedict XVI for staying to live at the Vatican and being like "a wise grandfather at home."
"A people who don't take care of their grandparents and don't treat them well is a people with no future. Why no future? Because they lose the memory [of the past] and they sever their own roots," he said.
