In 1985 Dave Hunt and T.A. McMahon began a ministry for the purpose of encouraging spiritual discernment among those who regarded themselves as biblical Christians. The primary vehicle for this endeavor was through the publication of the newsletter The Berean Call. Behind every article is the exhortation to believers to get back into the Word of God instead of being "carried about by every wind of doctrine," and to equip them with materials to help them walk in the truth.
