This book is about the role of the concept of covenant in religion, understood as agreements between humans and deities (or even other supernatural beings), and the theological implications thereof. Since this concept is most prominent in Judaism and Christianity, it inevitably focuses primarily on them - but will include information about that concept in any religion in which it occurs. It does not include religious groups which happen to have "covenant" in their name (such as Covenant of the Goddess, Covenant of Unitarian Universalist Pagans). Nor does it include covenants between human beings, which do not claim to have a deity or other supernatural being as a party, even if those covenants happen to concern religion; for example, the Solemn League and Covenant in Scottish history, of the Scottish Covenanters, the Covenant of Umar I and the Pact of Umar II (which has also been called a Covenant).
