Final answer:
The question pertains to the belief in bodily transformation at the resurrection, common in Christian tradition and also reflected in various cultural myths, including Russian folklore, wherein the incorruptibility of a body is seen as a sign of saintliness or heroic endurance.
Step-by-step explanation:
The question 'What must this mortal body put on when the dead are raised incorruptible?' delves into the theme of resurrection and incorruptibility within religious beliefs and cultural myths. This concept is tied to religious doctrines and the afterlife, which are a part of social studies education when it contributes to understanding cultural and religious beliefs. In the Christian tradition, this phrase can be loosely associated with the idea that for eternal life or resurrection to occur, the mortal body would be transformed into an immortal and incorruptible one. The notion of an enduring, uncorrupted body connects to tales from various cultures, including Russian folklore which envisions revered leaders rising to aid their people in times of need. The Russian Orthodox faith has a historical belief in the non-putrefaction of the body as a sign of holiness, although this is not a requirement for sainthood. The incorruptibility of the body, serving as a sign of sanctity and heroism, echoes this sentiment and is encapsulated by the veneration of Lenin's embalmed remains and how he entered folklore.
