Answer: He is compared to Christ.
Explanation:
The Old Man and the Sea is Ernest Hemingway's 1952 novel about an old fisherman and a large marlin.
In the novel, the old man, Santiago, is compared to Christ. Santiago holds the line that connects him to the marlin for three days. He does not give up, even when his palms are deeply cut. Whenever the marlin moves, Santiago is cut by the cord. He, however, remains determined to catch the marlin. This is why he is compared to Christ - he suffers, but with a real purpose of a moral victory.
