Unlike many traditional churches experiencing a decline in membership, Shincheonji’s Thomas Tribe has seen a steady increase in believers. Since its establishment in 1992, the tribe has grown significantly, with young adults making up 22.25% of its congregation. This trend contrasts sharply with the overall decrease in young Christian believers in Korea.

What sets Shincheonji apart is its structured and in-depth Bible education programme. Many churches offer sermons that vary by denomination, often leading believers to seek teachings that align with their personal views. However, Shincheonji provides a systematic Bible study programme that lasts six to eight months, allowing believers to gain a comprehensive understanding of the Bible, including the Old Testament, the Gospels, the Book of Acts, and Revelation.

Those who have completed Shincheonji’s Bible course often express how it has answered their long-held spiritual questions. Many testify that the teachings provide clear and logical explanations of the Scriptures, deepening their faith and transforming their understanding of God’s word. One believer shared that after 30 years in a traditional church, she found Shincheonji’s structured Bible teachings to be revolutionary, helping her grasp both the prophecies and their fulfilment in a way she never had before.

The church continually refines its educational methods based on feedback from members, ensuring that believers not only acquire biblical knowledge but also put it into practice. Many members engage in personal study groups and set faith-based goals to apply what they learn in their daily lives.

One of the core teachings of Shincheonji is to become a “walking Bible” – someone who not only understands the Scriptures but also lives according to its teachings. Believers strive to embody biblical principles such as love, forgiveness, and service in their workplaces, homes, and communities.

A member from the Thomas Tribe expressed his commitment to attending all Bible education sessions this year, hoping to become a person who can confidently explain the Bible and practice its teachings. Many others share similar goals, viewing their faith not just as a belief but as a way of life.

The Thomas Tribe began with just 78 members in 1994. Since then, it has expanded its reach to the United States (San Jose and San Francisco) and Africa (Uganda and Kenya). The church in Uganda, which started with 27 members in 2015, saw its membership grow more than 300-fold over the course of 10 years, and in 2025, 100 local pastors participated in the 'Public Bible Examination on the Book of Revelation.' Building on this success, the church has signed agreements with 37 organizations in Uganda, Kenya, and other regions, and is actively engaging with over 300 churches abroad. The Thomas Tribe has now grown to nearly 20,000 members as of February 2026.
