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.
Mind and body altering narcotics are condemned by the church for a plethora of reasons. Firstly, because they alter our mental state and draw our mind away from God, but mostly because of the waves of excessive vice which follow the drug trade.
