Founded in January 1876, the congregation began when the valley was still a frontier of orchards, wheat fields, and small settlements. Early members—many of them farmers and pioneers—established a church rooted in Christian faith and service, laying foundations that have endured for generations.

As the region grew and changed, the church grew alongside it. From the early 20th-century interurban railway to the expansion of agriculture and education in the valley, the Milton church served families on both sides of the Oregon–Washington border. Throughout world wars, economic shifts, and social change, it remained a place of stability, fellowship, and compassion.

Over the decades, the church has supported Christian education, youth programs, and community service initiatives, including food and clothing assistance. Today, it continues to serve a diverse congregation while remaining focused on its mission of sharing Christ’s love with the community.
