Raising children is one of the most important tasks of society. The future of all humanity depends on what our children will be like. There are different approaches to education and different pedagogical conceptions of education. One of the educational pedagogical concepts is Montessori pedagogy. It was created at the beginning of the 20th century, but it is contemporary even today. The founder of this pedagogical concept is Marija Montessori. She made a radical turn in her approach to children. She understood that children are little explorers who need freedom to develop successfully. But along with gaining freedom, children must learn to be responsible. Marija observed the children's needs and formed the settings of her pedagogy based on that. She understood that children are religious beings and that religion is an important part of their development. She did not develop a separate religious education, but rather incorporated religion into all dimensions of education. The goal of this paper was to show the importance of religious education for the overall development of children and how religious education and Montessori pedagogy go side by side. Also, one of the goals was to present a model of religious education based on the principles of Montessori pedagogy, which is called the Catechesis of the Good Shepherd. Man is a religious being from his very beginnings. Ever since he knows himself, man has been looking for God. Since the need for the transcendental is a fundamental human need, it is important to enable children to satisfy it. Religious education begins in the family and continues in kindergarten and school. At the same time, it is important to look at the child as a collaborator in the learning and upbringing process. Montessori pedagogy is guided by the idea that children are capable of learning on their own if they are provided with the necessary conditions, and the educator is only an aid for the child to complete the task on his own. We find the combination of these two ideas, that man is a religious being and that a child is a little researcher, in the Catechesis of the Good Shepherd program. This program combines the methods of Montessori pedagogy and giving children the opportunity to meet God, who is the Good Shepherd.
