Baptism stands as the fundamental sacrament of Christian initiation, regarded not only as the gateway to the Christian faith but also as the entry point into the life of the Church itself. Its roots are profoundly biblical and deeply interwoven with the theological and ecclesiological fabric of the Catholic Church. The history, the theological significance, and the rich tradition of Baptism reflect both the continuity of the early Christian practices and the development of Church doctrine through the centuries. From its first mention in the Gospels to its theological and liturgical maturity in the writings of the Church Fathers, Baptism has always been an essential pillar of the Christian identity.
