Initiation sacraments in canonical and liturgical law

The Church sanctifies the world primarily by celebrating the liturgy and administering the sacraments. In the Catholic Church, we distinguish seven sacraments instituted by Jesus Christ. The thesis discusses the so-called initiation sacraments, baptism, confirmation and the Eucharist. Their acceptance is required in the case of repeated reception of the Eucharist for full initiation into the Christian life. The most sublime Eucharist is the source and at the same time the peak of all our actions. The thesis refers to both the biblical/historical roots and particularly to the current canonical and liturgical practice of administering initiation sacraments from the point of view of the canon law of the Latin Church (CIC/1983), the canon law of the churches of the Eastern Rite sui iuris (CCEO), official liturgical books (e.g., General Instruction of the Roman Missal) and other documents of the magisterium and relevant church authority concerning the liturgy
