In a world where the population is growing day by day and in which more than eight billion people, members of different religions and cultures, live, it is necessary to pay more attention to intercultural communication. This graduate paper examines the influence of religion on intercultural communication and the need to understand intercultural communication. Understanding the importance of intercultural communication is preceded by an understanding of the concept of culture and its elements. The common elements of each culture were considered, and for a simple idea of cultural dimensions, the most famous model of cultural dimensions, Hofstede's model, was used. Using secondary sources of information, this paper presents numerous examples which explain in detail the dimensions of culture and facilitate their understanding. Potential barriers that may arise during communication between two cultures are also shown, and it is explained how to adapt behavior in intercultural communication and avoid potential barriers. Also, culture is studied in the paper in different contexts, and the greatest emphasis is placed on intercultural communication in the business sphere. Furthermore, the concept of religion is explained, the division of religious traditions is stated and the main characteristics of the five major world religions are presented: Christianity, Islam, Hinduism, Buddhism and Sikhism. The influence of religious traditions on communication between cultures is emphasized. At the end of the paper, examples of good practice are listed to avoid misunderstandings and potential conflicts and to achieve successful business cooperation, i.e. profit, which is the main goal of every multinational company.
