APOSTOLIC EXHORTATION
SACRAMENTUM CARITATIS
OF THE HOLY FATHER
BENEDICT XVI
TO THE BISHOPS, CLERGY,
CONSECRATED PERSONS
AND THE LAY FAITHFUL
ON THE EUCHARIST
AS THE SOURCE AND SUMMIT
OF THE CHURCH'S LIFE AND MISSION
INTRODUCTION
1. The sacrament of charity (1), the Holy Eucharist is the gift that Jesus Christ makes of himself, thus revealing to us God's infinite love for every man and woman. This wondrous sacrament makes manifest that "greater" love which led him to "lay down his life for his friends" (Jn 15:13). Jesus did indeed love them "to the end" (Jn 13:1). In those words the Evangelist introduces Christ's act of immense humility: before dying for us on the Cross, he tied a towel around himself and washed the feet of his disciples. In the same way, Jesus continues, in the sacrament of the Eucharist, to love us "to the end," even to offering us his body and his blood. What amazement must the Apostles have felt in witnessing what the Lord did and said during that Supper! What wonder must the eucharistic mystery also awaken in our own hearts!
