This Sunday's Gospel (Luke 12:13-21) tells the parable of the Rich Fool, who stores up his crops and goods in barns, never thinking that he can't take them into eternity with him. “Fool! This night your soul will be required of you; then whose will those things be which you have provided?”
In a General Audience on October 20, 2004, St. (Pope) John Paul II spoke about covetousness and wealth:
“In his riches, man lacks wisdom: he is like the beasts that are destroyed” (Psalm 49: 13). In other words, untold wealth is not an advantage, far from it! It is better to be poor and to be one with God.... A profound blindness takes hold of man if he deludes himself that by striving to accumulate material goods he can avoid death. Not for nothing does the Psalmist speak of an almost animal-like “lack of understanding.”
...The rich man, clinging to his immense fortune, is convinced that he will succeed in overcoming death, just as with money he had lorded it over everything and everyone. But however vast a sum he is prepared to offer, he cannot escape his ultimate destiny. Indeed, like all other men and women, rich and poor, wise and foolish alike, he is doomed to end in the grave, as happens likewise to the powerful, and he will have to leave behind on earth that gold so dear to him and those material possessions he so idolized.
