This paper offers a comparative analysis of the New Testament Church (NTC) and its Mount Zion community in Taiwan, drawing on an extensive review of the scholarly literature and interviews conducted on Mount Zion itself. The study reconstructs the movement's origins, its theology of a "new" Mount Zion transferred from Israel to Taiwan, and the development of its utopian community under the leadership of Elijah Hong (who passed away in 2025). Particular attention is given to the 1980s-1990s confrontation between the NTC and Taiwanese authorities, including police raids, administrative pressure, and attempts to restrict the community's activities. These events are examined as an early example of the tensions that can arise between new spiritual movements and state institutions in Taiwan. By placing the Mount Zion saga in a broader comparative framework, the paper highlights continuities between the treatment of the NTC and later cases—most notably Tai Ji Men—showing how patterns of suspicion, bureaucratic overreach, and moral panic have periodically shaped the state's response to minority religions. The analysis argues that the Mount Zion case remains essential for understanding the evolution of religious liberty issues in Taiwan and the challenges still faced by new spiritual movements today.
