Religion and culture are important issues in inter-cultural exchange, particularly in the case of Christianity. Christian missionaries have changed gradually from an attitude of superiority to open discussion on matters of local culture. This essay focuses on the comparison between the traditional ritual of giving names in Yami society and Catholic baptism for newborn infants. The goal of this essay is to stimulate further communication between the two different cultures. The Yami people of Orchid Island have their own traditional ritual of giving names (both to the infant and to the parents), which has been handed down for generations. The rites of the Yami people, such as dripping water into the hair root, rites of naming and blessings, have many similarities with Catholic baptism, both in form and symbolic meaning. In the past fifty years, both rituals have been applied in parallel among the Yami Catholics. Nevertheless, there is no metal understanding between them. In the future, further communication and learning may broaden the horizon for the tow cultures. Indigenization remains an essential issue for the Catholic Church to strife for.
