Concerned Christians

Monte Kim Miller formed a group known as the Concerned Christians in Colorado, during the 1980s. Created as an element of the Christian countercult movement to combat New Age religious movements and anti-Christian sentiment, it has shifted to more of a apocalyptic Christian movement as the group adopted the less mainstream views of the millennium held by Miller.

There is a separate and unrelated evangelical Christian ministry known as Concerned Christians, an outreach to Mormons in transition out of Mormonism, based in Mesa, Arizona, that was established in the 1970s, and adheres to mainstream, traditional Christian doctrines and teachings. There are also other unrelated organizations that use "Concerned Christians" as part of their name.
