For some groups, nothing more than a couple of sections entitled "Info At a Glance" (name, purpose, attitude toward Christianity, quotes from leaders) and Doctrinal Summary (view of God and Jesus, salvation, death, the Bible, Heaven and Hell).

Other groups such as the Mormons, Jehovah's Witnesses, Baha'i, Masonic Lodge, Unitarianism, Unification Church, The Way International, and Zen, have more detailed information.

As an evangelical Christian, I do not have a problem with the book's approach (contrary to several previous reviewers) - after all, since Jesus made claims and performed feats that no other leader could make or back up, does it not make sense to measure what other religious groups believe compared to Biblical Christianity? Unfortunately, too many earlier reviewers trash the book without being honest about how their beliefs line up with Christianity.

I do wish the book had more information on various groups such as Christian Science, Silva Mind Control, UFO Cults, and Yoga as these groups have recently been making the news and have infiltrated some corporate training methods.

Complaint aside, I recommend the title as a good source for finding out what other religious groups really believe and how they compare to Biblical Christianity!
