The Mission Churches of the CCCAS serve Samoan communities across the United States, New Zealand, and Australia. Rooted in the same doctrine, worship life, and congregational polity as the mother church, these congregations provide a spiritual home for Samoan families living abroad.

Formed as Samoan migration expanded in the mid‑20th century, the Mission Churches preserve faith, family, and cultural identity through worship, fellowship, and pastoral care. They offer Sunday schools, youth and women’s ministries, and community outreach that nurture intergenerational faith and strengthen Samoan Christian life in the diaspora.  These congregations embody the CCCAS’s commitment to proclaim Christ, uphold Samoan heritage, and serve Samoan communities wherever they reside.

As of 2026, the CCCAS currently ministers and provides services to 8 mission churches, located in: Clarksville, Tennessee; Hilo, Hawaii; Lawton, Oklahoma; El Paso, Texas; Suisun City, California; Medford, Oregon; Midvale, Utah; and Sydney, Australia.

These mission churches are made up of Samoan families and communities who live in areas that are distant from CCCAS member churches.  To begin the process, these communities would first request the CCCAS for a missionary to help begin their own congregation in the area in which they live.  The CCCAS would then send a missionary to provide ministerial services to the community for a period of 4 years.  During this period, the CCCAS would sponsor the missionary and his family financially (monthly allowance and accommodations assistance).  The hope is that after 4 years, the mission church would grow into a self-sufficient and self-supporting church.

The CCCAS Missions Committee oversees all requests and correspondences from mission churches, as well as the selection of missionaries who are sent to assist in their development and minister to their spiritual needs.
