The new mortal sins were listed by Archbishop Gianfranco Girotti at the end of a week-long training seminar in Rome for priests, aimed at encouraging a revival of the practice of confession.
These lists contain movies that focus heavily on these sins, showing us that these vices are not only prevalent, but a key focus of our popular culture! Maybe the Vatican is onto something.
Wealth has always been frowned upon by the Christian church, Jesus himself asked all his disciples to ditch their belongings in order to follow him. Our spiritual connection to God can get clouded by the desire to accumulate trappings, and we can find ourself worshipping our goods over our God. It is a well known fact that "It is easier for a camel to pass through the eye of a needle, than it is for a rich man to get into heaven".
