Though located downtown and serving that community, the vision of the church is broader.
In 1951, one of its first mission projects was the “boys at Scott” Air Force Base. The church sponsored devotional and recreational opportunities for airmen at the church and other locations. Union has sponsored missionaries around the world.
Since 1993, church youth have traveled annually on mission trips to destitute communities to rehabilitate houses and perform other community projects, mitigating dire circumstances and lifting spirits. By 2009, youth had made mission trips to 14 states and Puerto Rico.
In 2007, Union began satellite church services in Freeburg to reestablish a United Methodist presence in that area of St. Clair County.
In 2008, Union funded part of the construction of New Hope United Methodist Church in Monrovia, Liberia, as well as purchase of land for future expansion.
Union United Methodist Church is a downtown church whose message of hope and vision of service are not bound by geographical limits.
