The second sticheron at Saturday evening Vespers begins: "The books will be opened.." I had always wondered about that sticheron, and the plural of "books" rather than "book," as in "the book of life." When St. John writes that each "book" is the soul of each man, it certainly becomes clear.
I will this evening try to remember to post these stichera from the files in my computer -- in which most of the teaching of the Church on the Last Judgment is summarized.
It was interesting -- while reading that I realized that this passage fit with my (new, beginning) understanding of the Orthodox mindset. So different from what seems like, by comparison, the legal mindset of the West.
