随着近期学术界由宗教对话引起对多重宗教归属(multiple religious belonging)和多重宗教身份(multiple religious identity)的讨论不断加增,宗教对话已进入了另一个阶段,一个建构自我宗教身份的阶段。在这个原因下,其他宗教便成为建构自我宗教身份的元素。因此本文首先讨论多重宗教归属和多重宗教身份的差别,其次本文讨论东亚基督徒的双重宗教身份的实况和宗教传统在历史中演变的问题。最后,从比较神学的方法,特别以南乐山(Robert C.Neville)的波士顿儒家学说来回应儒耶双重宗教身份的可行性。 With the recent debate in religious circles over multiple religious belonging and multiple religious identities arising from the rise of religious dialogue, religious dialogue has entered another phase of construction of self-religious identity. For this reason, other religions become elements of self-religious identity. Therefore, the article first discusses the differences between multiple religious affiliations and multiple religious identities. Second, the article discusses the reality of the dual religious identity of East Asian Christians and the evolution of religious traditions in history. Finally, from a theatrical theological approach, particularly the Boston Confucian doctrine of Robert C. Neville, responds to the feasibility of dual religious identity in both Confucianism and Judaism.
