Another Gospel: Cults, Alternative Religions, and the New Age Movement is a non-fiction book on cults, destructive cults, new religious movements, and the New Age movement, written by Ruth A. Tucker. The book was published by Zondervan, in 2004.
Another Gospel focuses on groups active since the 1960's, and explains both how these groups seem to meet people's needs, and how others can reach out to cult members. Tucker relates key historical controversies within each group or movement as they strive for religious respectability. The groups' practices and beliefs are compared and contrasted with those of orthodox Christianity.
