AN INTRODUCTION TO JUDAISM IN CHAPTER 16: The book "The sixteen chapters for knowledge Judaism" are the result of several years of work between the offices of the General Secretariat of the Italian Episcopal Conference - CEI - (National Office for Ecumenism and Interreligious Dialogue; National Office for Education, Schools and Universities; National Service for the Teaching of the Catholic Religion) and the Union of Italian Jewish Communities - UCEI). All this is a concrete expression of mutual esteem and fruitful collaboration based on open and honest dialogue, respect for differences and a deep knowledge of traditions. Underlying this project is a shared concern for the proper knowledge and transmission of a religious culture that can implement a process of mutual understanding and - specially - counteracting and preventing antisemitism. This joint work represents a real dialogue process that was initiated by the conciliar breakthrough in Nostra Aetate n.4 is alive and effective, with the aim of providing different educational agency systems (including Italian schools with quality IRC texts) promoting culture and knowledge as a true antidote to all forms of anti-Semitism competently, for the growth of our communities and society as a whole.
