The Mystery of the Holy Eucharist
As taught in the Catholic tradition
The source and summit of the Christian life, containing the real presence of Christ.
Within the Catholic tradition, the "Sacramental Economy" refers to the communication or "dispensation" of the fruits of Christ’s Paschal Mystery through the celebration of the Church’s sacramental liturgy. At the very heart of this economy—functioning as its "source and summit" (CCC 1324)—is the Mystery of the Holy Eucharist. The fundamental question this subtopic answers is: How does the resurrected Christ remain physically and substantially present to His Bride, the Church, until the end of time? The Catholic answer is not found in a mere symbol or a temporary spiritual visitation, but in the dogma of the Real Presence—the belief that under the appearances of bread and wine, the Lord Jesus Christ is "truly, really, and substantially contained" (Council of Trent).
