本論文是一個歷史神學研究的練習。這個神學研究辦法是從初期不同群體基督徒中去看,經過了幾年後他們還持續相信的與他們所做的是什麼,嘗試理解在他們正式信仰體系中,是什麼與他們記錄下的。本論文將感恩聖事的研究方法做一種優先性地討論,也就是說感恩聖事是被經驗到的,而非實踐上的安排,如同將這樣的實踐視為神學的延長。感恩聖事是一個行動(ergon),它早先於討論 (logos)。當我們理解到這一點,後續的研究進路就會回到很容易的回到初期教會與教父學的著作研究中。這個觀念是一種光照,如同當我們沉浸在光中,我們會真正了解感恩聖事的真正意義是在基督內感謝天父。本論文嘗試在教派合一運動中跳躍過雙方的衝突點,嘗試在禮儀中開始實踐合一的對話與行動。
This thesis is an exercise in historical theology. This theological approach seeks to examine what various groups of Christians have continued to believe in and do over the years, closely adhering to what they have as an official set of theory, to provide roots for essential reflection. Whether I can form a background for inquiring further traditional theological questions, such as what is the fundamental essence of the Catholic council’s understanding regarding the Eucharist, and providing a central essence for discussions on SACROSANCTUM CONCILIUM from Vatican II council, such as whether or not there is a solution to solve the traditional dilemma between churches, and whether or not returning to our past can enable us to see a brand new future.
