The following list of key concepts for review may be found in 7 Secrets of the Eucharist, p 57, by Vinny Flynn

• The Eucharist is the source and summit of Christian life - Lumen Gentium

• At the words of a mere creature, the bread and wine cease to exist, but all their scientific properties remain

• Even the tiniest particle of what our senses still perceive as bread and wine is now Christ

• Christ’s presence is not symbolic or partial, but real and complete.

• Christ is truly present just as He is in heaven, alive and glorious

• Christ does not leave heaven. His existence in heaven is not multiplied, but made present-not only in one place-but in every place where Mass is being celebrated

• Only Christ is present sacramentally under the appearance of bread and wine but He is not alone. The Father and the Holy Spirit and all of heaven are present with Him

• During each celebration of the Mass we are lifted out of time and into eternity to participate with the angels and saints in one divine liturgy that is being continually celebrated in heaven as Christ offers His once-for-all sacrifice to the Father

• The priest is united to the Eucharist in such a unique and exceptional way that he receives a “specific sacramental identification” with Christ, which thus enables him to offer the Holy sacrifice in the person of Christ

• Through the Eucharistic sacrifice, the “entire created universe is united.”
