This study addresses the issue of social equality in the ancient catechumenate, presenting it as a way of Christian initiation in which the significance of social divisions characteristic of the ancient world was deliberately limited. In the preparation for baptism, people from diverse backgrounds took part: both free persons and slaves, the rich and the poor. Shared formative practices - including listening to the Word during catecheses, participation in liturgical celebrations, and engagement in ascetical and penitential practices helped to level these differences and to foster attitudes of equality and fraternity. The aim of the study is to show how the structure, practice, and theology of the ancient catechumenate responded to the social inequalities of the ancient world and to what extent they contributed to overcoming them within Christian communities. The analysis takes into account both the historical and social context as well as source testimonies drawn primarily from the writings of the Church Fathers. An analysis of the texts, especially selected catecheses from the fourth century, demonstrates that the catechumenate not only prepared candidates for the reception of the sacrament of Christian initiation, but also shaped the social dimension of Christianity, in which members of the community perceived themselves as equal before God, regardless of social status. In turn, an analysis of catechumenal liturgical rites, such as the enrollment of names, exorcisms, and scrutinies, reveals their universalistic character. These celebrations were conducted in the same manner for all catechumens, symbolically emphasizing the equality of their situation before God and the community.
