Day 194: Summary of the Sacrament of the Eucharist

Having passed from this world to the Father, Christ gives us in the Eucharist the pledge of glory with him.

CCC 1419

In today's reading, the Catechism gives a short "In Brief" section for everything that has been covered over the past few days.  I've said all that I need to on this for now, but I did want to show something from the Catechism Compendium that is applicable here:

It contains the whole spiritual good of the Church, Christ himself, our Pasch. Communion with divine life and the unity of the People of God are both expressed and effected by the Eucharist. Through the eucharistic celebration, we are united already with the liturgy of heaven and we have a foretaste of eternal life. (#274)

Participating in the Mass and receiving the Eucharist allows for ongoing encounters with God and the reception of his grace, shaping our lives and leading us closer to him. (p. 152)

Finally, Dr. Brant Pitre gives a more in-depth examination of the biblical roots of the Eucharist in this video that essentially captures what the Catechism teaches on this:
