20世纪的西方近现代史见证了宗教信仰的式微,这一现象在英国文学的“天主教小说”中有所体现。本文选取英国小说家伊夫林·沃的四部天主教小说《衰落与瓦解》《邪恶的肉身》《一捧尘土》《旧地重游》,从教会神职人员的失职行为、教众对宗教的亵渎行为和信仰约束力量的松弛三个方面探析20世纪宗教信仰的世俗主义发展态势。 The 20th century’s modern Western history has witnessed the decline of religious beliefs. This phenomenon is reflected in the “Catholic novels” of British literature. In this paper, we select four Catholic novels of the British novelist Evelyn Waugh, “Decline and Disintegration”, “Evil Body”, “Dusty Hands” and “Re-visit the Old Land”, from the dereliction of duty of the church clergy to teach the public to desecrate religion And the Relaxation of the Restrictive Beliefs in the 20th Century.
