Holy Communion
Just as in the early Church, the Eucharist completes our initiation as Christians. While all the sacraments lead us into the mysteries of Christ in a divine manner and make us part of His body, this is particularly true in the Mass.
The Catechism tells us that the Eucharist is “the source and summit of the Christian life.” It is also where we give thanks to God for all He has done for us. In fact, the Greek word eucharistia means thanksgiving.
Luke tells us that Jesus made Himself known to the Emmaus disciples in the breaking of the bread. But before this happened, Jesus prepared them for the eucharistic meal with an explanation of how He fulfilled the prophecies and types of the Old Testament.
