The article describes the specifics of Religious Identity in a Christian Context. When analyzing such complex phenomenon as religious identity, it should be noted that it cannot be classified according to only one type of typology. Such classification may narrow an understanding of the subject matter. At least three types of religious identity shall be considered: a religious identity itself in its broadest sense, a confessional identity and an institutional identity. Each of these identities reveals different sides of religious consciousness, starting from a belief in the supernatural and ending with a particular type of world-view which implies everyday religious practices and inclusion in the church community. All these types have their own identification markers and a researcher can choose them in accordance with a particular research context. Both opposing approaches- to consider the respondents as orthodox Christians according to their self-identification or to study everyday religious practices of the respondents in detail- are equally unsuitable. Furthermore, the number of typological criteria can be reduced by using the Western theological grounds for identifying the believers. Unlike the Eastern Orthodoxy, Catholic practices include the believer’s obligation to fulfill certain actions prescribed by the Commandments of the Church. It makes the connection between the religious beliefs of Catholics and practicing of such beliefs in everyday life obvious. If catholic criteria are used for identifying Orthodox Christians, it will help to reveal such identity more precisely and make the connection between a particular world-view and its everyday practice more clear.
