The Church of Christ in Thailand elected Boon Mark as general secretary in 1938, a position which he held until after World War II. During the war, the Japanese occupation forces prohibited public Christian worship services, and confiscated Christian church buildings, schools, and hospital. Boon Mark traveled widely throughout Thailand at this time, encouraging members of the CCT to endure the difficulties that they were facing.
Advocacy for Pentecostalism

In 1948, Boon Mark withdrew from the Church of Christ in Thailand because he did not agree with the CCT's decision to join the
World Council of Churches
The World Council of Churches (WCC) is a worldwide Christian inter-church organization founded in 1948 to work for the cause of ecumenism. Its full members today include the Assyrian Church of the East, most jurisdictions of the Eastern Orthodo ...
. He objected to liberal theology and ecumenism which Boon Mark viewed as a compromise of Biblical Christianity.
After his departure from the CCT, Boon Mark became associated with Pentecostal missionaries from Finland and became an early advocate for Pentecostalism in Thailand. Boon Mark played an important role in the 1956 Bangkok crusade meetings of American Pentecostal healing evangelist
T.L. Osborn, for whom he translated during the meetings.
Boon Mark later associated himself with the
United Pentecostal Church
The United Pentecostal Church International (UPCI) is a Oneness Pentecostal denomination headquartered in Weldon Spring, Missouri. The United Pentecostal Church International was formed in 1945 by a merger of the former Pentecostal Church, Inc. ...
(UPC), a group whom he met on a visit to the United States. From the UPC church denomination, Boon Mark learned of the
"Jesus Only" teaching, which maintains that Christians should be baptized only in the name of Jesus, not in the name of
God the Father or the Holy Spirit. When Boon Mark brought the "Jesus Only" teaching back to Thailand and began teaching it in Thai Pentecostal churches, some people agreed with him, while others did not. The division caused a split within the Pentecostal churches in Thailand. The United Pentecostal Church initially experienced rapid growth in Thailand, but then experienced rapid decline after Boon Mark withdrew from the group in the late 1960s.
Founding of Thailand's first independent church
In 1957, Boon Mark founded Bangkok Church, the first independent church in Thailand. He also founded the Association of Independent Churches in Thailand, of which he served as general secretary.
