To be fair to Zoe Knox, the following shows the scope of her book.
=================
This book examines how Jehovah’s Witnesses have challenged the jurisdictions of modern states and influenced understandings of religious tolerance and freedom of worship worldwide. Their influence is all the more remarkable given that they aim to remain aloof from the world. This detachment differs markedly from many other religious organisations. … The Watch Tower Society is remarkably insular. Whilst it engages with the secular state through courts of law, this is to a narrow end, namely opposing attempts to inhibit the public ministry of Witnesses. They have unintentionally championed the rights of a wide range of other religious minorities around the world. The Society has long acknowledged the broader impact of its legal advocacy but has never presented this as a motivation for legal challenges.
In addition to how and why Jehovah’s Witnesses have come into conflict with governmental authorities, this book also explores the ways in which the secular world has shaped the organisation. Like other religious groups, the Society has had to respond to new technologies, secular ideologies, and geopolitical configurations to avoid obsolescence. Its interpretation of scripture has altered along with worldly developments, which has in turn led to new policies, some of which have posed novel challenges to governments. Since 1971, the Society’s doctrines have emanated from the Governing Body, a group of men based at the world headquarters. Between seven and eighteen men have served on the Governing Body at any one time. The Body has determined policies and procedures that shape the behaviour of Witnesses worldwide. This includes public conduct, such as deportment when manning information stalls, and intimate acts, such as the sexual positions permitted between husband and wife. These behavioural guidelines sometimes shift: sexual relations within marriage are now regarded as a matter of individual conscience, for example.
More generally, the rapid pace of the modern world has challenged it to adapt to ever-changing conditions, just as it has the leadership of other Christian churches. The theological foundations of even the best known of the Society’s doctrines have not been investigated by historians, nor has the evolving position of the Governing Body on these issues. (Knox, 5-6)
