The Catholic Church has always paid great attention to catechesis. Throughout its long history, the Catholic Church has brought up countless generations of Catholics with the help of Catechesis. Recently, it has been noticed that difficulty in approaching young people. Institutions like the Family and the Catholic Church simply don't reach the young like they used to. The goal of the Catholic Church is to approach children and young people with the help of catechesis in the hope of regaining their trust. Catechesis must be adapted to the group with which the good news is shared to. One of the groups that belong to compulsory catechesis is the altar servants who are the subject of this thesis. The key feature of every ministerial community is catechesis. The initial part of the thesis presents and explains the meaning of ministerial service itself through various biblical examples and by various blesseds and saints who were altar servants in their way during their earthly life. After the presentation of the ministerial community and its foundation on examples supported by the Bible and the lives of various saints and blesseds, we move on to the very essence, that is, the catechesis of altar servers. It is divided into three important parts that are necessary for the catechesis of altar servers, namely: the liturgical aspect, the social-charitable aspect, and "communio", that is, togetherness. In the last part, their characteristics and markings are presented, and the emphasis is placed on togetherness as the main characteristic of the ministerial community. The work ends with the third chapter, which talks about the birth of future spiritual vocations through ministerial communities. Three aspects that are important for spiritual vocations are particularly emphasized, namely: Family, parish community, and Pastor.
