Guzman Carriquiry, Vice President Emeritus of the Pontifical Commission for Latin America (Cal); Fabrice Hadjadj, writer and philosopher; Maria Francesca Righi, Abbess of the Cistercian Monastery of Valserena; Joseph Weiler, University Professor at NYU Law School and Senior Fellow at the Center for European studies at Harvard. Introduced by Roberto Fontolan, Director of the International Centre of Communion and Liberation.

On 15 October 1922 was born Luigi Giussani, priest, educator, founder of the Communion and Liberation movement, and great friend of the Meeting (where he spoke in 1983 and 1985). Four exceptional witnesses speak about his figure and work: two met him in person and two did not. What emerges is a multi-voiced, original and profound portrait.
