Introduction

In the final installment of the five-part series on the Luminous Mysteries, Dr. Ben Akers, Executive Director of Formed, engages in a profound discussion with Dr. Mark Gieshek, a distinguished colleague from the Graduate School of Theology at the Augustine Institute. The episode delves into the fifth Luminous Mystery: the Institution of the Eucharist, exploring its theological significance, historical roots, and spiritual implications for the faithful.

Defining the Mysteries of Light

Dr. Ben Akers opens the conversation by thanking supporters of the Mission Circle, emphasizing the role of monthly donations in facilitating such in-depth Bible studies. He introduces the Luminous Mysteries as concepts introduced by Pope St. John Paul II in 2002, positioned between the Joyful and Sorrowful Mysteries to highlight aspects of Jesus' public ministry.

[00:53] Dr. Mark Gieshek explains the terminology:

"Jesus says, I am the light of the world. And so John Paul II names them Mysteries of Light because light indicates revelation, right? Divine revelation." (00:53)

He prefers "Mysteries of Light" over "Luminous Mysteries," arguing that "light" better encapsulates the idea of spiritual enlightenment and divine revelation rather than the physical concept of light.

The Institution of the Eucharist

The discussion transitions to the core theme: the Institution of the Eucharist. Dr. Gieshek unpacks the term "institution," emphasizing its meaning as establishing a perpetual practice:

"It's to establish, to originate, to inaugurate. It's to begin something." (01:57)

He underscores that Jesus instituted the Eucharist as an enduring sacrament, intended to be a continuous practice until the Second Coming:

"He establishes it as a practice for all of history, right? Until the Second Coming." (02:04)

Eucharist as Sacrifice

A common misunderstanding addressed is the notion that the Mass re-sacrifices Jesus. Dr. Gieshek clarifies:

"We're united to the one sacrifice of Christ for all time through the Mass. So the Mass truly is a sacrifice." (03:05)

He emphasizes that the Eucharist is not a repeated sacrifice but a participation in the singular, eternal sacrifice of Christ:

"It's not as though Jesus gets re-sacrificed... but that he undergoes his death and resurrection for all people, for all time, and we're united to that through the Mass." (03:21)

Connection to the Passover and Old Testament

Linking the Eucharist to the Old Testament, Dr. Gieshek draws parallels between the Institution of the Eucharist and the Jewish Passover:

"The Eucharist fulfills the Jewish Passover and anticipates the final Passover of the Church in the glory of the kingdom." (04:58)

He explains that Jesus reinterprets the Passover meal by positioning Himself as the sacrificial lamb, thus transforming the traditional observance into a new covenant:

"Jesus is the sacrificial victim who's also officiating over the banquet." (07:27)

New Covenant vs. Old Covenant

The conversation shifts to the transition from the Old Covenant to the New Covenant, highlighting continuity rather than contradiction:

"The New Covenant idea is like a really helpful way of thinking about that... what the Lord is doing in the New Covenant is not a contradiction of the Old Testament." (10:43)

Dr. Gieshek references Jeremiah 31:31, illustrating how Jesus fulfills and surpasses previous covenants:

"Jesus is the new Abraham, he's the new Moses, he's the new David." (13:22)

Theological Concepts: Transubstantiation and Sacramental Life

Exploring the theological depth of the Eucharist, Dr. Gieshek touches upon transubstantiation and the Eucharist as the "source and summit" of Christian life:

"The Mass is the true center of the Sacred Liturgy and indeed of the whole Christian life." (14:58)

He cautions against misconstruing this centrality as the entirety of one’s spiritual life, emphasizing that the Eucharist leads believers towards an eternal communion with God:

"It's the highest point of communion with God on earth, and yet it's meant to lead us into the even greater reality of the eschatological banquet." (15:03)

Relation to the Cross and Holy Week

Linking the Eucharist to the events of Holy Week, Dr. Gieshek explains the interplay between Jesus' sacrifice and the liturgical celebrations:

"The Holy Thursday liturgy never really ends, and the Good Friday liturgy never exactly begins... the liturgy begins on Holy Thursday and doesn't really end until the end of the Easter vigil." (18:02)

He elucidates that the Eucharist and the Passion of Christ are inextricably connected, forming a unified narrative of sacrifice and resurrection.

Conclusion and Invitation

As the episode concludes, Dr. Akers highlights the profound mystery of the Eucharist and previews forthcoming discussions on the Sorrowful Mysteries. He invites listeners to engage in the Luminous Mysteries, particularly on Thursdays, to deepen their understanding and support the mission of the Augustine Institute:

"We invite you to join us if you pray the luminous mysteries, the Mysteries of Light if you pray them on Thursdays." (17:00)

Dr. Gieshek adds a final reflection on the spiritual communion achieved through the Eucharist:

"We eat his resurrected body." (18:55)
