1936年12月12日，張學良、楊虎城發動西安事變囚禁蔣介石。軟禁期間的聖經閱讀和自身的宗教經驗，使蔣確信西安事變為其一生之中至為重要的經歷。事變期間，基督教界為蔣舉行各式祈禱大會，為營救蔣而積極奔走，並在蔣獲釋後又發電祝賀及舉行慶祝活動。蔣也投桃報李，一再公開對教界表示感謝。次年耶穌受難節，蔣公開發表證道演講，為西安事變建構出了一個的「宗教版本」。蔣在演講詞中塑造自身的基督宗教信仰與神學道統，強調自己是耶穌基督和三民主義的信徒。此演講在中外教界廣為流傳，教界人士紛紛撰文宣傳、形塑蔣的宗教身分與信仰。西安事變中所透視出的蔣與教界的互動，成為了蔣宗教信仰政治化表述和西安事變宗教化表述的有效展現。

Zhang Xue-liang and Yang Hu-cheng started the Xi'an Incident on December 12th, 1936. Chiang Kai-shek relied on the Bible to overcome the predicament during his detention. Reading the Bible and his religious experience convinced Chiang that the Xi’an Incident was the most important experience for his whole life. In the course of the incident, Christians in China not only organized prayer meetings for his safety but also strived to rescue him. After Chiang was released, they sent a telegraph to congratulate him and celebrated his release. Chiang Kai-shek was so grateful that he declared his gratitude to Christianity. On the Good Friday of 1937, Chiang Kai-shek delivered a speech sharing his experience as a Christian witness and came up with an explanation of the Xi'an Incident, which was informed by religion. He tried to shape his Christian faith and theological orthodoxy. Chiang reinforced his commitment to Jesus and the Three Principles of People. His speech was widely spread among Christians both in China and overseas. They wrote articles to propaganda and shape Chiang's religious status and faith. Therefore, the interaction between Chiang and those Christians during the Xi'an Incident mirrored the politicized expression of Chiang's faith and religious narration of Xi'an Incident.
