Final answer:
The correct answer is option c. In Christian belief, Christ is referred to as 'the first fruits of those that sleep,' which means Jesus's resurrection is considered the first instance of resurrection, symbolizing hope for all believers.
Step-by-step explanation:
The reference to 'the first fruits of those that sleep' in a Christian context refers to Christ. This is a metaphor used to describe Jesus Christ's resurrection as the first instance of someone rising from the dead, paving the way for the resurrection of all believers. It signifies that Christ is the first to rise and therefore preeminent in the Christian faith. This concept is particularly tied to the teachings and writings of St. Paul, who played a crucial role in defining early Christian theology.
Despite the various interpretations of Jesus's teachings, the underlying belief in the resurrection and its significance remains a central tenet of Christianity. St. Paul describes this concept in 1 Corinthians 15:20 where it says, "But now is Christ risen from the dead, and become the firstfruits of them that slept."
