Religious elements such as prayer, personal experience of faith, mystical religious experience are religious phenomena that greatly influence the human psyche. Religiosity as a personal emotional relationship with God became the subject of study by many psychologists and experts and due to their interest became the beginning of the creation of the psychology of religiosity as a scientific discipline where the effect of religiosity on the human psyche, personality development, own identity, personal growth and development is studied. Many great psychologists such as Sigmund Freud, William James, Carl Gustav Jung, Viktor Frankl and others made their contribution to the psychology of religiosity. The two most important theories of moral development, Jean Piaget and Lawrence Kohlberg, discovered that the beginnings of moral judgment in children begin with seeing the consequences of human actions, i.e. with a reward for a good deed and a punishment for a bad deed. We have seen that religious experience as one of the phenomena of religiosity cannot be examined due to the lack of examination and research instruments, as well as the still present approach to religiosity and religion as a general, traditional and institutionalized form of faith, although it is obvious that in modern times individual and private religiosity. We also emphasized the importance of including religious symbols and values in the upbringing and development of personality, the characteristics of mature religiosity, and the psychological training of pastoral workers and counselors with an emphasis on sensitivity and care for people.
