" The first Christians were eucharistic by nature: they gathered for “the breaking of the bread and the prayers.” They were formed by the Word of God, the “apostles’ teaching.” When they met as a Church, their worship culminated in “fellowship”—the Greek word is koinonia, communion. The Mass was the center of life for the disciples of Jesus, and so it has ever been. Even today, the Mass is where we experience the apostolic teaching and communion, the breaking of the bread and the prayers. "
