Neither Kim Sung-do, nor Baek Nam-ju recorded their doctrines, which meant that they
disappeared with the groups’ dissolutions, and the division of the peninsula. However,
due to Kim’s documenting his efforts, this new biblical interpretation did not disappear,
and was spread to the south and became the canon for countless groups in the country,
including the Unification Church and JMS. Despite the continuation of the books in
Theology of the Holy Spirit (聖神神學) published in January, 1954; Basic Principle of
Christianity (基督敎根本原理) released in March, 1958; and Theory of Personality and Faith
(信仰人格論) published in October, 1970; Kim’s core doctrine can be summarized as three
main ideas (Euh, 2008: 216-221):
a) The history of Salvation is divided into three different periods, connecting it to the
concept of the Trinity. In other words, each entity of the Trinity (Father, Son and
Holy Spirit) fulfils its role during a different time period. In this way, God governed
the Old Testament, the Son ruled the New Testament, and the Holy Spirit controls
the third and last stage when the second advent takes place, named the Complete
Testament. According to Kim’s theological vision, the Old Testament and the New
Testament referred to an old and a new promise respectively. Just as the name the
Complete Testament indicates, it is the time when God completes or fulfils this
promise. Furthermore, March 2, 1946 is considered as the last day of the New
Testament, also as the first day of the Complete Testament. Despite the alleged
uniqueness and singularity of this exegesis presented in the Theology of the Holy
Spirit (聖神神學), the truth is that Kim simply elaborated Baek’s idea of the “Path of
a New Life”.
b) Kim distinguished Jesus’s physical nature and spiritual nature by using two
different names: Jesus and Immanuel. Jesus referred to the human body and
Immanuel to the spirit. In this way, the second coming was interpreted spiritually,
where the spirit (Immanuel) descends to earth and uses the body of a chosen person.
Kim proclaimed himself as being the Messiah, denying Jesus’ physical coming, and
emphasizing his mission to his followers. Once again, the shamanic concept of
spiritual possession was nothing new, but existed as a similar phenomenon among
Kim’s predecessors.
c) The original sin was the result of sexual transgression. Kim differentiated the
concept of salvation into ‘spiritual salvation’ and ‘solving the problem of hereditary
sin’. Jesus’ redemption involved salvation from spiritual death and reconciliation with
God. However, solving the problem of hereditary sin, meaning sexual transgression,
could only be done by a person who reveals the essence of the original sin and guides
humanity, so as to “restore” it to the original state before the fall. Therefore, Kim
emphasized “restoration” beyond salvation. This core doctrine is summarized in the
Basic Principle of Christianity, which is divided into three parts: the principle of
creation, the principle of the fall, and the principle of restoration. To this extent, Kim
Sung-do’s influence is indisputable, yet he enhanced it by including the concept of
restoration, which he used to justify and emphasize his mission as the second coming
messiah.
Similarly to his predecessors, Kim Baek-moon failed to succeed in gathering a consistent
number of followers, and in conserving a well-organized group. Yet his books established
the theological foundation for most of the NRMs that emerged after the Korean War,
