This study would investigate how the Family Federation for World Peace and Unification, a new Christian religion, understands death and the educational implications in its understanding of death. Since the preceding studies do not deal with the aspect of the change of the independent term by which the Family Federation for World Peace and Unification refers to death, their contents are restrictive and limited. Thus, this study investigates the process of the change of the term for death in the Family Federation for World Peace and Unification too to discuss its educational implications. The Family Federation for World Peace and Unification considers the death of the physical self man encounters the inevitable Providence of the One and Only God. It believes that man consists of the physical self and the spirit self and was created to live forever as the object of the love of the One and Only God as the spirit self in the spiritual world after the death of the physical self. The man’s living on this land with the physical self is also ultimately a process of preparing for eternal life after the death of the physical self through the growth of the spirit self on the ground of the physical self. Thus, the Family Federation for World Peace and Unification does not understand the death of the physical self as something to be feared or sad for. Also, since the death of the physical self is interpreted not as the price of sin, it neither emphasizes the rebirth of the physical self nor mentions the necessity of it. The Family Federation for World Peace and Unification has expressed death as ‘Seunghwa’ but currently refers to death as ‘Seonghwa.’ Seunghwa was a term referring to death, which emphasized the dimension of the migration of the spirit self as told by the Family Federation for World Peace and Unification. In other words, it had educational implications that would make people aware of another world after death and overcome the fear and sorrow of death. Death as Seonghwa has an educational significance that emphasizes the completion of life as a believer who realized religious ideals. The expression of death as Seonghwa on the other hand provides the opportunities for the reflection and awakening of how one has lived as a believer, compared to Seunghwa. In other words, death reconceptualized as Seonghwa suggests how death should be recognized in the life of a believer of the Family Federation for World Peace and Unification by maximizing the meaning of death as the completion of life.
