"This large yet lucid volume is not only a recapitulation, in somewhat more popular terms, of the author’s monumental study of apokatastasis, or universal restoration, in early Christian thought; it carries the story forward to the middle ages, adds material on annihilationism, and digests the author’s previous work on the meaning of the word aionios into an appendix--all with an unmatched command of primary sources and scholarly literature." --Mark Edwards, Professor of Theology, University of Oxford
