Education in religion is based on the relationship between parents and children, but in today's society, the traditional way of life that places emphasis on raising children and strengthening family ties no longer prevails. Faith is thereby thrown into the background and becomes something without which it’s possible to function in society. This important role is played by the Church, which should cooperate and help parents. The work itself begins with an introduction to the mystery of the Eucharist, which highlights the importance of the Eucharist for life, and especially for catechesis. After that, attention is directed towards the role of the Eucharist as the source and goal of catechesis, and the emphasis is on the phrase "Eucharistic catechesis". In the third chapter, we will talk about the first communicants, since the Eucharistic catechesis is aimed at them, but also about the family, which plays an immense role in the life of the first communicant. The work ends with the fourth chapter in which the guidelines for the Eucharistic catechesis of first communicants in today's society are derived.
