This is the first master degree paper to investigate into the process of PCT’s joining, leaving and rejoining of WCC. It is broken down into three periods: from joining to leaving, 1951-1970; from leaving to rejoining, 1970-1980; from rejoining to establishing an example for Taiwan’s international participation, 1980-1991. At the end of the paper, a chapter on the integrated study of PCT’ ecumenism is added to provide a complete study. This part of the paper breaks the history into five periods: beginning, 1948-1965; political intervention, 1965-1970; reestablishment, 1970-1980; break-through, 1980-1988; maturity, 1988-1991. These five periods of PCT ecumenism is the structure set by this study.
The five periods mark the process of PCT’s ecumenical involvement from encountering to maturity. The beginnings of both PCT and WCC have to do with unity as a matter of faith. The ecumenical spirit of the PCT is the reason behind its joining and rejoining the WCC. The sending churches of Taiwan’s missionaries and the help and advice of Rev. Dr. Shoki Coe were the key to the joining. The unity movement of Taiwanese local churches was also proposed by him. The leaving of WCC was caused by the ideology of the KMT government and the political intervention of ICCC. It resulted in the failure of the unity movement of Taiwanese local churches and the only General Assembly Meeting to fail to convene as a protest to the government in the history of PCT. It also resulted in the decisive turn in PCT's attitude toward political-religious relationship. The WCC was careful enough to postpone reviewing the application to leave and continued to keep a one-way communication with the PCT. This was the key to PCT’s rejoining. Meanwhile, GS Rev. Kao was set up by the KMT government as representing the PCT to hide political prisoner Shih Ming-teh. PCT finally turn from passively complying with the KMT government policies to actively confessing the practices of ecumenical care for society. The three documents of PCT were significant with “Our Appeal” as the most representative in this respect. And the Confession of Faith of the PCT is representative of the ecumenism of the PCT. Ecumenism of the PCT is the main part of Taiwanese ecumenism. It not only helped KMT government to change its mind about the WCC, but also helped the WCC during its seventh assembly to abandon the clause requested by the CCC to force Taiwan to leave upon its own joining. In the process PCT makes WCC a real fellowship of churches and helps Taiwan in its international isolation to establish a model of joining international meetings. The ecumenism of the PCT is an important part of Taiwanese ecumenism.
The essence of PCT ecumenism is its bottom-up unity rooted in this land. When faced with political crises, it based itself in the “confessing” tradition of the Reformed tradition to care for the society. The way of the cross is glorification through suffering.
