本文首先嘗試分析田立克以道的基督論到聖靈基督論的轉移，以解決整個神學本質和神學方法論的企圖仍然不成功。其核心主題「獨特性—普遍性」的張力無法得到妥當的處理。本文接著以一個田立克於1913年的作品中所重視、卻在晚期作品中忽略的三一觀點重整問題，在三一整個豐富和富果效的象徵中，使得上述的問題得以解決。

This paper, firstly, demonstrates the internal problem of Paul Tillich’s theology in general and theological method in particular in shifting his logos Christology to Spirit-Christology. The motif “particularity-universality” as a key notion is not well-balance through the theological development. Secondly, this paper proposes that the doctrine of Trinity, well-articulated in Tillich’s 1913 work and finds little attention in his mature work, provides a more fruitful and embracing symbol to release the tension and keep it in a dialectical way.
