The Christian Research Institute produced early radio broadcasts addressing cults, new religious movements, and doctrinal errors from an evangelical perspective. These programs aimed to equip listeners to discern truth and respond to false teaching.
Major works included question and answer segments and teaching on doctrinal issues. Some critics argued that the tone could be overly combative, but the broadcasts helped establish apologetics and discernment programming as a genre on Christian radio.
Apologetics and discernment broadcasts focused on evaluating cults and doctrinal errors.
