五十年前，在二十世紀影響教會的關鍵事件──第二屆大公會議（梵二）──結束之際（1965年12月8日），羅馬公教會頒布了《教會對非基督徒態度宣言》（Nostra Aetate, NA) ，定立了教會針對其他宗教的評價方式，成為與他教交流的里程碑。該宣言承認了宗教在人類歷史上所發揮的中心角色，從此，人類的存在便被認定為是各宗教間交流和互惠的具體平台。宗教應更加團結，扮演其最擅長的角色，追求人類存在的種種迷思和痛苦的解答。對於走在相互對話道路上的信仰者而言，時逢《教會對非基督徒態度》宣布五十週年之際，實為認識共同關切議題的好時機，同時也是各宗教團體相互努力，共思如何為更多的合作和共同的發展鋪路的好機會。

50 years ago (Dec 8,1965), at the conclusion of Vatican II, the greatest event marking the life of the Church in the 20th Century, the Roman Catholic Church issued “Nostra Aetate.” The declaration has been a landmark for the Church’s relation and appraisal of other religions. It acknowledged the central role religions play in the history of humanity. Humanity has henceforth been identified as the concrete platform calling on interactions and cross-fertilization among religions. Religions are to be more united in what they are best at: striving for answers to the existential riddles and sufferings of human persons. For those on the path of dialogue, the 50th anniversary of NA is an opportune occasion to acknowledge shared concerns and to ponder on how respective efforts of religious groups pave the road to more cooperation and mutual enrichment.
