The rise and spread of new religious movements, like the Unification Church, the Children of God, and the Hari Krishnas, have brought a lot of reactions from Jews and Christians alike. This paper examines the problem of how Christians should react and respond to these proselytizing groups. It is stressed that ridiculing the so-called cults is hardly an academic procedure and much less a viable theological and pastoral solution. Two responses, one by the National Council of Churches and one by the Lutheran Church are briefly described and evaluated. Finally, some guidelines towards a Christian theological and pastoral approach to the cults are proposed.
