Since its founding in 1958, St. Stephen's has established itself as a progressive Christian community working for peace and social justice issues.
In the ‘60s, the congregation increasingly questioned America’s involvement in Vietnam. In the ‘70s, St. Stephen’s ratified the Charter for Racial Justice, which was developed by the Board of Global Ministries. During the ‘80s, the church supported a plethora of peace initiatives, including a Peace with Justice Program, an annual memorial to bombing victims of Hiroshima and a task force that provided support and sanctuary for refugees from Central America.
