This book deals with many of the heresies and false groups that challenge Bible-believing churches today.
The introductory section contains an extensive survey of what the New Testament says about false teachers and a study on biblical separation. The next section is on the Roman Catholic Church. This is followed by a section on three of the major cults, Mormonism, Seventh-day Adventism, and Jehovah's Witness.
The next section contains an extensive study on the Pentecostal-Charismatic movement, its history and doctrine. The final section covers Modernism and New Evangelicalism.
Each study is comprehensive and thoroughly-researched.
