They devoted themselves to the apostles' teaching and fellowship, to the breaking of bread and the prayers.... Day by day, attending the temple together and breaking bread in their homes, they partook of food with glad and generous hearts. 166
Catechism number 1343
It was above all on "the first day of the week," Sunday, the day of Jesus' resurrection, that the Christians met "to break bread."167 From that time on down to our own day the celebration of the Eucharist has been continued so that today we encounter it everywhere in the Church with the same fundamental structure. It remains the center of the Church's life.
