This paper attempts to explore the issues of religious object collection through a case study of Taiwan’s first religions-themed museum, the Museum of World Religions. One of the questions it looks at is what are the differences between collection of religious objects and collection of other types of objects? It seems that sacredness is the most important differentiating factor, as religious objects are collected by museums due to their sacred implication. This paper will also discuss the themes and connections of collecting and religion and examine how this museum interprets religious objects, represents them in exhibitions and brings out their sacredness.
