The International Missionary Society Seventh-day Adventist Church Reform Movement, also known as IMS, is a distinct organization that originated in Germany shortly after World War I. Comprised of former Seventh-day Adventist members who were disfellowshipped for openly opposing the church's support of the war, IMS holds strong beliefs in Christ's work in the Sanctuary, Saturday observance, health reform, and organization. The IMS offers a range of products and services to support their mission.

These include the Know Your Bible and New Horizons Bible Course for online study, the Reformation Course for those seeking a deeper understanding of their faith, and the Miracle Makeover Health Course to promote holistic well-being. Additionally, they provide weekly Sabbath School lessons for children, youth, and adults, as well as literature downloads, books, and newsletters. With locations worldwide, including in Ontario, Quebec, Alberta, British Columbia, and the USA, IMS welcomes individuals to explore their teachings and engage in their community of believers.
