Why it is wrong to disparage the Eucharist.

"... may all of us who share 

in the body and blood of Christ 

be brought together in unity by the Holy Spirit."

- Eucharistic Prayer II

"The unity of the Mystical Body: the Eucharist makes the Church."

1324 The Eucharist is "the source and summit of the Christian life."136 "The other sacraments, and indeed all ecclesiastical ministries and works of the apostolate, are bound up with the Eucharist and are oriented toward it. For in the blessed Eucharist is contained the whole spiritual good of the Church, namely Christ himself, our Pasch."137

1325 "The Eucharist is the efficacious sign and sublime cause of that communion in the divine life and that unity of the People of God by which the Church is kept in being. It is the culmination both of God's action sanctifying the world in Christ and of the worship men offer to Christ and through him to the Father in the Holy Spirit."138

1326 Finally, by the Eucharistic celebration we already unite ourselves with the heavenly liturgy and anticipate eternal life, when God will be all in all.139

1327 In brief, the Eucharist is the sum and summary of our faith: "Our way of thinking is attuned to the Eucharist, and the Eucharist in turn confirms our way of thinking."140 - CCC

"The Eucharist is thus constitutive of the Church's being and activity."

When we dedicate ourselves to reparation for offenses committed against the Eucharist through adoration of the Blessed Sacrament outside of Mass, it seems to me we should be even more scrupulous to avoid any suggestion or attitude that could be interpreted as divisive to the Body of Christ.

"It is significant that the Second Eucharistic Prayer, invoking the Paraclete, formulates its prayer for the unity of the Church as follows: "may all of us who share in the body and blood of Christ be brought together in unity by the Holy Spirit." These words help us to see clearly how the res of the sacrament of the Eucharist is the unity of the faithful within ecclesial communion. The Eucharist is thus found at the root of the Church as a mystery of communion (35)." - The Eucharist and Ecclesial Communion
