This study examines the five passages in the Epistle to the Hebrews which are traditionally regarded as references to Christ's Second Coming (Hebr 1,6; 9,28; 10,25.36-39; 12,24-29). The starting point is the contention that apocalyptic references to the parousia do not match the thinking of the rest of the epistle, which is determined rather by a Middle Platonic ontology. In order to resolve this tension, part 1 undertakes a close textual analysis of the problematical passages in the Letter to the Hebrews, and in part 2 these are related to relevant texts by Philon, Plutarch, Seneca and Alcinous, which are also subjected to close analysis. Part 3 finally syntheses the results of the first two parts and shows that it is plausible to accept that the author of the Letter to the Hebrews has undertaken a Middle Platonic transformation of the notion of the Second Coming.
