In light of shared moral responsibility to help the millions of people who are bought, sold, transported and held against their will in slave-like condition, a conference entitled “A Call to Action: Joining the Fight Against Trafficking in Persons” was held at the Pontifical Gregorian University in Rome on June 17, 2004. The event was part of the 20th anniversary celebration of full diplomatic relations between the United States and the Holy See, and their shared work to promote human dignity, liberty, justice, and peace.
