This work is a systematic exposition of the internal meaning of all but the last three chapters of the book of Revelation. Apocalypse Explained seems to be an uncompleted, earlier rendition of the teachings presented in more concise form in Apocalypse Revealed. It is much longer than Apocalypse Revealed. The nature of the Divine, the order of the heavens and the union of the Divine with the created world through new revelation emerge as the key teachings of this work. Like the Arcana, the Apocalypse Explained sets forth internal meanings of many passages in the Bible in books other than Genesis, Exodus, or Revelation, which are the only three books of the Bible which receive detailed, systematic exposition.
这部作品系统地阐述了启示录除最后三章以外的所有章节的内在含义。《启示录注释》（Apocalypse Explained（AE），1757-1759；6卷本，1232节）早于《揭秘启示录》（Apocalypse Revealed(AR)，1764-1766；2卷本，962节））一书，似乎是后者所呈现的教义（以简洁的形式）的一次未完成的、更早期的注释，比《揭秘启示录》要长得多。上帝的本质、天堂的秩序以及上帝与受造世界的联合通过新的启示形成本部作品的关键教义。与《属天的奥秘》一样，《启示录注释》阐述了圣经中除创世记、出埃及记和启示录之外的许多章节的内在含义。创世记、出埃及记和启示录是圣经中仅有的得到史公详细而系统阐述的三卷书。对创世记、出埃及记的阐述可参见《属天的奥秘》，对启示录的阐述可参阅《揭秘启示录》和本书。
