Although the idea for a document concerning the rela-tionship with the Jews was proposed by Pope,now Saint,John XXIII already in the initial preparations for the Council,this was eventually abandoned in favor of a text speaking tothe variety of religions present in the world today.PopeJohn's concern for the Jewish people is clearly expressed inthe profound final paragraphs of Nostra Aetate(NA),whichhave had far reaching impacts on relations between Catholicsand Jews.But the remainder of the document has alsobrought about a radical transformation in relations with otherreligious communities.One aspect of NA of particular interest It is also the fiftieth anniversary of Nostra Aetate(theDeclaration on the Relationship of the Church to Non-ChristianReligions)promulgated on October 28,1965.Nostra Aetateremains one of the most controversial,as well as one of themost influential,documents of the Council.It laid a theo-logical foundation for a more fruitful relationship betweenthe Roman Catholic Church and adherents of non-Christianreligions,opening new doors for interacting with non-Christians and affirming the work that had already begundecades earlier by many who had lived in close proximitywith members of other religious communities.It is a veryshort document,only six long paragraphs.Yet its length isdeceiving.The final product reflects careful and numerousrevisions intended to express continuity with orthodox teachingwhile pointing a way forward toward overcoming the tensionand strife that has plagued past relations with other religious continued on page 2 Dr:Sandra Toenies Keating is the Director of the Develop-ment of Western Civilization Program and AssociateProfessor of the Department of Theology at ProvidenceCollege,Providence,RI.

FAQs

What is Nostra Aetate, and why is it important to Christian witness?

Nostra Aetate is a Vatican document on the relationship of the Church to non-Christian religions. It provides a theological foundation for more fruitful relations while shaping Christian witness through more careful engagement across faiths.

How did Nostra Aetate change Catholic relations with other religious communities?

It moved from a pre-conciliar approach that drew strict boundaries to a framework that recognizes varying degrees of commonality and difference. The text points to shared elements of truth while also affirming substantial differences among religions.

Why does lack of Christian unity affect dialogue and witness to Muslims?

The lack of unity is described as a major stumbling block because it creates divisions that the Qur’an cites as evidence that Christians abandoned God’s true religion. The article links this directly to the urgency of visible Christian unity.
