2012-04-27 L’Osservatore Romano“The confrontation of diversity and sincere dialogue becomes a growth factor for justice and peace. This does not eliminate differences, on the contrary it intensifies dialogue”. This was enclosed in the message sent by Cardinal Tarcisio Bertone, Secretary of State, to participants in a seminar onf the person and works of Giuseppe Toniolo, on the value of the testimony of the founder of Italian Catholic Social Weeks, rightly considered the precursor to the Church's social teaching, beginning with Rerum novarum, and from Quadragesimo anno to Caritas in Veritate. The meeting's slogan is significant in this regard: “In the school of Giuseppe Toniolo”, organized in these days coming up to the Beatification of the great Italian economist and sociologist – which will be celebrated Sunday 29 April, in the Basilica of St Paul Outside-the-Walls – by five institutions which in some way are rooted in the teaching of Toniolo, in collaboration with the Pontifical Councils of Justice and Peace and for the Laity. The theme of the seminar is: “The commitment and the contribution of the laity within the international community for a more just, more peaceful and more humane world”.
