Hardly are there any issues in life that are more emotive and contentious than religion. Part of the reason for this is that rarely do any two religions agree on most of their teachings about deity and humanity: there is so much divisiveness and mutual distrust.
Christianity is not spared these mutual acrimony and disaffection, even within itself. Thus, there are inside it such characterizations as Orthodox, Pentecostals, Evangelicals, etc, with each claiming superiority of spirituality over and above one another, and citing portions of the Bible to argue its positions. But this has erected confusion in the minds of many, who find it difficult to dissect what are right or wrong doctrines in the face of one group of Christians accepting certain practices or beliefs, while another group condemns the same things.
Unzipped! traces these doctrinal crises, in part, to misrepresentation of the two parts of the Bible: Old and New Testaments, submitting that biblical Christianity is all about what Christ and His disciples taught and practiced. In other words, it posits that if Christ and His apostles did not teach or practice a doctrine, Christians do not have to bother about it. The book challenges all who call on the name of the Lord Jesus Christ to look up to, and live for Him, as the author and finisher of their faith. It therefore contends that biblical Christianity, as opposed to its religious version, does not admit of syncretism.
