在潘霍華《聖徒相通》中，他用跨學科的方法思考宗教共同體的二維性－－這種二維性在基督宗教的組織層面表現為啟示與歷史的二元張力。以往漢語研究把潘霍華早期關於宗教共同體的思考結構理解為我－上帝－他人這樣的單調線形結構。與此不同，本文意圖首先呈現《聖徒相通》方法論的複雜性和前瞻性，在此書中潘霍華綜合運用了哲學、社會學以及神學概念工具分析宗教共同體。其次，本文將追溯潘霍華思想的起源和發展，比較其與自由派神學家澤貝格以及辯證神學家巴特的相似性和重大差異。通過比較這三種思考進路，本文展示了潘霍華早期思想的獨創性。

In his doctoral dissertation Sanctorum Communio, Bonhoeffer develops an interdisciplinary method to study the two-dimensionality of the religious community, whose manifestation in Christianity is the church as revelation and the empirical church in history. Previous research on this issue among Chinese scholars has presented Bonhoeffer's ecclesiology as a simple I-Thou-you structure. Unlike earlier studies, this article aims to represent the methodological complexity and farsightedness of Bonhoeffer's ecclesiology, in which he analyses the religious community with philosophical, sociological and theological conceptual tools. Moreover, this article traces the origins and development of Bonhoeffer's thought, highlighting both its similarities with and significant departures from the ecclesiology of the liberal theologian Reinhold Seeberg and the dialectical theologian Karl Barth. By comparing these three approaches to ecclesiology, the present article shows the originality and the creativity of Bonhoeffer's early thinking.
