That sense of immediacy has presented problems for
interpreters, nowhere more so than for those like the Millerites who had a
detailed apocalyptic timetable for the end of the world and the consummation
of scriptural promises.When Christ failed to return in 1843–4 as they had predicted,
they searched the Scriptures and concluded that the error was not in
the word of the Lord but in their own understanding of it (in Foster in
Numbers and Butler 1987: 173–88).
