Part of his welcome address to the people of Slovakia:
"Do not be satisfied with the sole quest for economic advantages. Great affluence, in fact, can also generate great poverty"
It's a interesting paradox that nearly all good things can be turned on their head to become something disordered, misused - an object of sin. I'm sure many worldly people will think this quote is referring the struggle between the rich growing in their riches and the poor staying poor, but I'm sure he means more than that. Anything placed before God can create a poverty in our lives: the poverty of having love for things that will pass away.
I'm glad to hear that the Holy Father is persevering in the adversity of his failing health. He is striving to do the work of the Lord even to the end.
