of which God spoke through the mouth of his holy prophets from of old.
Conversion to Christ, the new birth of Baptism, the gift of the Holy Spirit and the Body and Blood of Christ received as food have made us "holy and without blemish," just as the Church herself, the Bride of Christ, is "holy and without blemish." Nevertheless the new life received in Christian initiation has not abolished the frailty and weakness of human nature, nor the inclination to sin that tradition calls concupiscence, which remains in the baptized such that with the help of the grace of Christ they may prove themselves in the struggle of Christian life. This is the struggle of conversion directed toward holiness and eternal life to which the Lord never ceases to call us.
-- CCC 1426
The disciples of Jesus recounted what had taken place along the way, and how they had come to recognize him in the breaking of bread. While they were still speaking about this, he stood in their midst and said to them, "Peace be with you."
From the beginning the Church has been faithful to the Lord's command. Of the Church of Jerusalem it is written:
In the first community of Jerusalem, believers "devoted themselves to the apostles' teaching and fellowship, to the breaking of bread, and the prayers." This sequence is characteristic of the Church's prayer: founded on the apostolic faith; authenticated by charity; nourished in the Eucharist.
