Final answer:
The passage implies that the Second Coming is a methodical, inevitable event, associated with solemn prophecy and terror, making Response B the correct inference.
Step-by-step explanation:
The passage implies that the Second Coming is man-made yet inevitable. It suggests a profound and solemn prophecy arising from darkness, an event that cannot be avoided or escaped, whether it is anticipated by social movements like the Shakers and Millerites, or forewarned as a historical certainty in Medieval inscriptions. The descriptions throughout the passages relate to the inevitability of the event, its methodical nature, and its association with terror, indicating that the correct inference would be that the Second Coming will be methodical and pitiless (Response B).
