Baptism
Holy Baptism is the basis of the whole Christian life, the gateway to life in the Spirit, and the door which gives access to the other sacraments. Through Baptism we are freed from sin and reborn as sons of God; we become members of Christ, are incorporated into the Church and made sharers in her mission: Baptism is the sacrament of regeneration through water in the word.
Eucharist
Through the act of consecration, the bread and wine become the true Body and Blood of Christ. Within the consecrated elements of bread and wine, Christ is truly, really, and substantially present: his Body and Blood, along with his soul and divinity. (CCC 1413)
Confirmation
Baptism, the Eucharist, and the sacrament of Confirmation together constitute the “sacraments of Christian initiation, whose unity must be safeguarded. It must be explained to the faithful that the reception of the sacrament of Confirmation is necessary for the completion of baptismal grace.
