What are some examples of Holden experiencing spirituality in Catcher in the Rye?

Holden Caulfield claims to be "sort of an atheist" but is evidently more spiritual than he is religious. In chapter 14, Holden elaborates on his thoughts regarding Christianity and Jesus. Holden comments on his distaste for the Disciples in the Bible and feels like they were constantly letting Jesus down. In an argument with Arthur Childs, Holden says that he feels Jesus would not send Judas to Hell while the Disciples would be the first to condemn Judas as the ultimate sinner. Holden's thoughts reveal his spirituality and genuine understanding of Christian ideals, such as mercy, forgiveness, tolerance, and compassion.
Similar to many aspects of society, Holden believes that Christianity has been distorted by zealous, "phony" individuals, who use religion to enhance their appearance and criticize others, which is one reason Holden refuses to attend Sunday service. While Holden does not entirely reject religion, his comments indicate that he has faith in Jesus's merciful nature. In the next chapter, Holden offers a donation to two nuns he meets in Grand Central Station. Once again, Holden depicts his spirituality by generously giving a donation to the nuns without ulterior motives. Holden is not concerned about saving his soul or being viewed as a giving person by society. He simply has a capacity for genuinely helping others, which corresponds to Jesus's inherent nature and reveals his spirituality in action.
