A Catholic survey found that the most common sin for women was pride, while for men, the urge for food was only surpassed by the urge for sex.
The report was based on a study of confessions carried out by Fr Roberto Busa, a 95-year-old Jesuit scholar. The Pope's personal theologian backed up the report in the Vatican newspaper.
Msgr Giertych said the most difficult sin for men to face was lust, followed by gluttony, sloth, anger, pride, envy and greed. For women, the most dangerous sins were pride, envy, anger, lust, and sloth, he added. The survey on a self-reported sins so there may be a bias in the results.
The Scotsman's Fiona MacGregor talked with four men about the report.
