In a meeting with Italy's Anti-Mafia Parliamentary Commission on Thursday, Pope Francis said that dismantling the mafia begins with a political commitment to social justice and economic reform.

Corruption "has a contagious and parasitic nature, because it does not nourish what good produces, but…it subtracts and robs," Pope Francis said Sept. 21.

The meeting landed on the 27th anniversary of the death of Servant of God Rosario Livatino, who was a deputy prosecutor in an Italian court before being killed by mafia for his fight against corruption.

Called a "Martyr of Justice" by John Paul II, the Italian magistrate was commended by Pope Francis, who also praised two other judges – Giovanni Falcone and Paolo Borsellino – both killed in 1992.

The Pope's criticism of the mafia made global headlines when he publicly denounced organized crime in 2014. He said members of it were "excommunicated," which was not a reflection of canon law per se but a call to conversion.

The fight against the mafia and organized crime is essential, the Pope said Thursday, particularly because "they steal the common good, taking away people's hope and dignity."

However, the battle extends beyond the mafia to corrupt organizations which must also be reclaimed and transformed – and this needs commitment on an economic and political level, he said.

First, authentic politics is an important form of charity, which can work "to ensure a future of hope and to promote the dignity of each person." And second, economic reform must be shifted to remove systems which magnify inequality and poverty.

The Pope warned that corrupt organizations can serve as an alternative social structure which roots itself in areas where justice and human rights are lacking. Corruption, he noted, "always finds a way to justify itself, presenting itself as the 'normal' condition, the solution for those who are 'shrewd,' the way to reach one's goals."

Earlier this year, Pope Francis expressed concern that these criminal groups were using economic, social, and political weaknesses as a "fertile ground to achieve their deplorable projects."

"The money of dirty affairs and mafia crimes is blood money and produces an unequal power," he said.

He said that these criminal organizations, whose members often claim to live a devout Christian life while continuing to carry out heinous crimes, create a "social wound."

He then challenged the international community to greater collaboration and determination to ensure justice and defense for the weakest in society.
