Sacramentum Caritatis §6

PART ONE

THE EUCHARIST, A MYSTERY
TO BE BELIEVED

"This is the work of God: that you believe
in him whom he has sent" (Jn 6:29)

The Church's eucharistic faith

6. "The mystery of faith!" With these words, spoken immediately after the words of consecration, the priest proclaims the mystery being celebrated and expresses his wonder before the substantial change of bread and wine into the body and blood of the Lord Jesus, a reality which surpasses all human understanding. The Eucharist is a "mystery of faith" par excellence: "the sum and summary of our faith." (13) The Church's faith is essentially a eucharistic faith, and it is especially nourished at the table of the Eucharist. Faith and the sacraments are two complementary aspects of ecclesial life. Awakened by the preaching of God's word, faith is nourished and grows in the grace-filled encounter with the Risen Lord which takes place in the sacraments: "faith is expressed in the rite, while the rite reinforces and strengthens faith." (14) For this reason, the Sacrament of the Altar is always at the heart of the Church's life: "thanks to the Eucharist, the Church is reborn ever anew!" (15) The more lively the eucharistic faith of the People of God, the deeper is its sharing in ecclesial life in steadfast commitment to the mission entrusted by Christ to his disciples. The Church's very history bears witness to this. Every great reform has in some way been linked to the rediscovery of belief in the Lord's eucharistic presence among his people.
