Introduction The literature of the American colonies was influenced by diverse aspects including religious, moral, and cultural. The religion was one of the most important and widespread matter that had influence not only on the belief of people and faith in God, but also on the literary tendencies. As the number and variety of authors of different religions and beliefs was enormous, the expression of their thoughts and opinions was enormous as well. Like Csabir (2001) describes the religious matter of Puritanism expressed in the American literature: “Although in literary criticism the Puritans’ social, cultural and political concerns have always been associated with the way they thought of their relation to the world, it has not been pointed out as such that it is precisely the conceptual framework of the Puritan mind that forms the social, cultural and political contexts of the Puritan world” (p.195). Main body Thus the most brilliant way of influence on people minds and their perception of the world was expressed by religious aspects inserted into works of literature. The work of Csabir (2001) represents the way with the help of which we can make a conclusion concerning the way Puritans expressed their opinion about America in order to understand their world in a larger context (p.196). The works of American literature of the 19 th century are closely connected with the religious aspects of Christianity, and the expression of Christian beliefs is a widespread aspect of the literature on the whole. All actions of people were justified by the biblical sources and tried to parallel their own actions with deeds of people mentioned in Bible and other religious sources; “Puritans justified their movement to America predominantly on the basis of their religion” (Csabir, 2001, p.197). The sings of the similarity are obvious even for people who have little interest in religion and Bible: “The shared abstract structure is basically the frame of a journey. There is a departure point; path, destination and movement, there are travelers, impediments and adversaries hindering the journey…” (Csabir, 2001, p.204). Thereby not only theological aspect is present in the works of American literature of the 19 th century; the literary sources reveal biblical connections of the present and past actions of different people. After having a short excursus into the aspects of Puritanism in literature, I find it necessary to analyze two certain works from the point of view of religion, theological influence and use, reference to biblical and Christian teachings. The novels influenced by theological concepts are “The Scarlet Letter” written by Nathaniel Hawthorne and “Huckleberry Finn” by Mark Twain. The novel “Scarlet Letter” represents a purely religious look on the problem of sin, moral values, social relations, and personal judgements. It tells the story of Hester Prynne; her sin; her suffering; her struggle for life, daughter and absolution of her mistakes; justification by faith and good works. This story does not only possess nature of Puritanism, it “presents a Puritan view of morality, practised in a constructive New England community which Hawthorne compares to the one where he dwelt and developed” (Taylor, 2005, p.135).
