Art plays a key role in a child's overall development, providing him with the means to express himself, explore and understand the world around him. It encourages creative thinking, aesthetic sensitivity, cultural awareness and expressive skills. In kindergartens, art activities allow children to explore and develop their abilities in different ways. The theoretical part of the paper indicates the role and significance of artistic expression in kindergartens in general, and then also in kindergartens with religious education. In kindergartens with religious education, art not only encourages children's creativity and development, but also integrates religious values and thematic content that are important for the child's spiritual growth. The paper mentions the ways in which artistic activities can be integrated with religious themes and motifs and contribute to the overall development of children, including their cognitive, emotional, social and spiritual growth. Furthermore, the paper presents the developmental stages of children's artistic expression, the role of educators in the child's creativity, which is extremely important, the connection between art and religious education, the wealth of church art, and religious themes and motifs in fine art.

Josip (Granešina) and DV "Butterfly" (Sesvete). Children's works with religious motifs and themes are shown, they show not only the child's creativity and imagination, but also their emotional and spiritual connection with the religious content that surrounds them in their life world and upbringing.
