The term of religiosity in children's literature is highlighted by the desire to raise the awareness of the religious identity that each person carries within themselves. When it comes to children, religious identity manifests itself through various religious elements (God, Saints, church, pious objects, sacraments, and religious ministers). In this paper, entitled Religious elements in reading for classroom teaching, a research approach analyzes various literary works written by exclusively Croatian authors who highlight religious elements. Personal knowledge of religious identity based on knowledge and promotion of religious values and love for God and the sacred is established with the help of those religious elements. Books and stories imbued with religious motives and messages are of great importance because children develop their own religious identity through them, and through various literary works imbued with religious elements the goal is to bring children to religious maturation and late mature Christian personality.
