本文首先介紹郎尼根思想中的多元主義。郎氏主張文化是多元的，每一個文化有一種或多種宗教，宗教是嵌在文化中的。因此，宗教也是多元的。辨識出多元文化為宗教交談提供了一個新的方式，即多元性是一種文化世界，在其中宗教交談被理解成宛如包含了文化交談。其次，探討原始儒家的天觀，即闡明孔子的自然之天、關懷之天和天命。再者，介紹基督宗教的天論，是以聖經中的創造與救援為主。最後，針對「天的屬性」、「創造和保存」、「孔子的仁與耶穌基督的愛」和「天人合一」四方面，進行原始儒家和基督宗教對於天觀的比對。

This paper first introduces the concept of pluralism in Lonergan’s thought. Lonergan argues that culture is plural. Every culture has a religion or religions. Religion is embedded in a culture. Thus, religion is plural. The recognition of plural cultures and religions provides a new way for interreligious dialogue. In other words, pluralism implies a new cultural world in which interreligious dialogue is understood as including inter-cultural dialogue. Secondly, the notion of Heaven in original Confucianism is investigated. It introduces Confucius’ nature of Heaven, care of Heaven, and the mandate of Heaven. Moreover, this paper explores the notion of God in Christianity. It discusses the creation and salvation in the Bible. Finally, the author focuses on four aspects: the attributions of Heaven/God, creation and sustaining power, love in the Bible and benevolence in original Confucianism, and the unity between Heaven and human beings to conduct a comparison between original Confucianism and Christianity.
