Limitation up front

In the material you provided, there is no text of Pope Leo XIV’s specific Regina Caeli meditations, so I cannot directly quote or track what he said in those particular broadcasts. What I can do is (a) draw out the Eucharistic theology that Pope Leo XIV expresses elsewhere in his Magisterial/Easter-era messaging and (b) show how the themes intrinsic to Regina Caeli (Easter proclamation of the risen Christ and Marian “pray/hope” posture) naturally reflect Catholic Eucharistic theology—especially as that theology is taught in authoritative Catholic sources. 1 2 3 4 5

The Eucharist as the Church’s “Easter reality”: Passover fulfilled in the risen Christ

A central way Regina Caeli “touches” Eucharistic theology is through the Paschal content of Catholic worship. In Catholic teaching, the Eucharist is not merely a reminder of Easter; it is the sacramental way Christ’s Passover is made present and active for the Church.

The USCCB explains that on the night before His Passion, Jesus instituted the Eucharist to perpetuate the sacrifice of the Cross and to entrust to the Church a memorial of His death and resurrection. 3

Pope Leo XIV echoes this Paschal-Eucharistic link explicitly in his homily in Equatorial Guinea: the Eucharist “is the source and summit of the Church’s life and mission,” and it is “Christ, our Passover, who gives himself to us,” and “the living Bread that nourishes us.” 1

How this reflects Regina Caeli (Easter Marian proclamation):

• Regina Caeli is typically celebrated in the Easter season as a proclamation of the risen Christ and the joy of hope. When that joy is interpreted within Catholic doctrine, it points to the Eucharist as the concrete sacramental presence of the same risen Christ “for nourishment,” not only as an idea. 1 3

Real Presence: Eucharistic presence corresponds to Easter “presence”

Even when Regina Caeli itself is Marian (rather than explicitly Eucharistic), the Easter proclamation of Christ’s living presence resonates with Catholic Eucharistic realism.

The USCCB summarizes Catholic teaching on the “Real Presence”: the Catholic Church professes that in the Eucharist bread and wine become the Body and Blood of Jesus Christ; Christ is “truly present, body, blood, soul, and divinity,” under the appearances of bread and wine. 3

Further, the Catechism-style doctrinal core is expressed in the Catholic Encyclopedia’s articulation of Trent’s teaching: the “Body and Blood of the God-man are truly, really, and substantially present… by reason of the transubstantiation” of bread and wine. 5

Pope Leo XIV, in an Easter-octave context (though not Regina Caeli text specifically), speaks in a way that harmonizes with this: “During these days of the Easter Octave, we believe deeply in the presence of the risen Jesus among us.” 2

How this reflects Regina Caeli:

• Regina Caeli’s Easter posture—hopeful confidence grounded in Christ’s Resurrection—fits naturally with the Church’s claim that the risen Lord is not absent from worship. Instead, He is present sacramentally in the Eucharist. 2 3 5

Sacrifice and memorial: Easter joy is not “past history,” but present offering

A second Eucharistic dimension that Regina Caeli’s Easter tone tends to presuppose is the distinction between mere recollection and sacramental memorial.

The USCCB states that Jesus’ institution of the Eucharist exists to “perpetuate the sacrifice of the Cross throughout the ages” and to give the Church a “memorial of his death and resurrection.” 3

Pope Leo XIV presents the Eucharist as Christ who “gives himself to us” (i.e., not only a remembered victim, but a living gift in the Church’s worship). 1

Benedict XVI also links Eucharistic doctrine to reverence for the mystery not only during Mass but also in Eucharistic devotion: the task is to perceive the “most precious treasure” “not only in the celebration of Mass but also in devotion to the sacred species which remain after Mass.” 4

How this reflects Regina Caeli:

• Regina Caeli is “Easter-shaped”: it speaks from the Resurrection. Catholic Eucharistic theology insists that Resurrection and Cross belong together sacramentally—Eucharist is the memorial that makes Christ’s Paschal reality present as sacrifice and nourishment, not as detached sentiment. 3 1

Adoration (“latria”) and the Easter logic of worship

Catholic Eucharistic theology culminates in worship: adoration of the sacrament is not optional symbolism; it is the Church’s response to Real Presence.

Benedict XVI cites Paul VI and the Church’s constant practice: the Church has “paid this great Sacrament the worship known as ‘latria’ which may be given to God alone.” 4

While the provided Regina Caeli texts are missing, Pope Leo XIV’s broader Eucharistic emphasis fits this logic of worship. In his homily, he frames the Eucharist as “the source and summit” and highlights Christ’s living presence and nourishment—precisely the kind of theological ground that generates Eucharistic reverence and adoration. 1

How this reflects Regina Caeli:

• Regina Caeli is ultimately worshipful prayer to Mary, oriented toward Christ’s Paschal victory. Catholic doctrine interprets that orientation as culminating in Christ’s living presence in the Eucharist—where the Church’s worship is directed to the risen Lord Himself (not to a merely symbolic remembrance). 4 3 1

Marian mediation and Eucharistic ecclesiology: Mary and “the Church’s Paschal mission”

Regina Caeli is addressed to Mary, and this can reflect Eucharistic theology through the Church’s Paschal mission: the Eucharist is “source and summit,” and Marian prayer belongs inside the Church’s life of faith.

Pope Leo XIV’s framing of the Eucharist as the source and summit of the Church’s life and mission means that Marian prayer (including during Eastertide) is not “separate devotion,” but sits within the Church’s Paschal worship that flows from and returns to the Eucharist. 1

Conclusion

Even without the exact text of Pope Leo XIV’s Regina Caeli in your provided materials, Catholic Eucharistic theology shows a clear structural correspondence with the Easter themes that Regina Caeli expresses:

• Easter joy corresponds to the Eucharist as Christ’s Passover and living Bread given to nourish the Church. 1 3
• The Resurrection’s presence corresponds to the Eucharist’s Real Presence through transubstantiation. 2 3 5
• The Resurrection is not merely remembered but sacramentally present as memorial and sacrifice. 3 1
• Easter worship tends toward adoration (“latria”) of the risen Christ present in the sacrament, extending beyond Mass in Eucharistic devotion. 4

If you can provide the specific Regina Caeli text(s) you mean (even a transcript of the Pope’s remarks), I can then do a direct, line-by-line theological investigation of exactly how his wording reflects these Eucharistic doctrines.
