Eucharist: believing in order to understand

Living during the period immediately preceding the great scholastic works of Aquinas, Bonaventure and others, St Anselm of Canterbury (c. 1033-1109), helped defend and deepen the Church's understanding of the Eucharist at a crucial moment in history. Yet, he lived after the controversy surrounding a certain Berengar of Tours (c. 999-1088) whose teachings raised serious questions about how Christ is present in the Eucharist and prompted the Church to articulate its doctrine with greater precision. 

For Anselm, faith receives what reason can never fully understand.  His distinctive contribution was not a detailed Eucharistic treatise but the theological method encapsulated in his famous phrase fides quaerens intellectum ‘faith seeking understanding’.  Though he did not in a specific reference to the Eucharist, his famous phrase from the Proslogium is worth repeating:

A disciple's charter

Lectio Divina:*

Revelation 7:2-4 Psalm 24 (23) 1 John 3:1-3 Matthew 5:1-12

(See also Luke 6:20-23)

Meditatio:

‘Rejoice and be glad, for your reward is great in heaven, for in the same way they persecuted the prophets who were before you.’ (Matthew 5:12)

Commentary:

Religion often gets a bad name. It is accused of spreading gloom, fear or a spirit of killjoy, and many today contrast religion with spirituality as if they were opposites—religion = bad, spirituality = good. The phrase ‘I’m not religious but I am spiritual’ is now commonplace, sometimes spoken with a hint of self‑protection, as if being ‘religious’ were old‑fashioned, reactionary or faintly embarrassing.

What would a scientist find?

The mechanics of the transformation that occurs at every Mass have been the subject of controversy since at least the Reformation in the sixteenth century. Although Eastern Orthodox and Western Catholic Christians use different terms and theological language to explain the change that takes place, it seems clear to me from what I have read, seen and heard that they share the same essential conviction: the bread and wine taken, blessed and offered in the Eucharist become the Body and Blood of Jesus Christ. What was once ordinary food is no longer ordinary food. The belief that Christ is truly present in the Eucharist and that a real transformation takes place is consistent with what Christians believed, taught and practised from apostolic times onwards.

At the time of the Reformation, this ancient consensus was fractured, even though the original disputes arose largely in other areas of doctrine, particularly the nature of salvation, the role of Scripture and the authority of the Pope.

A sacrament of divine love

Two great saints of the thirteenth century, St Thomas Aquinas the Dominican and St Bonaventure the Franciscan theologian and bishop, provided different but complementary insights into the Eucharist. St Thomas Aquinas is especially known for his explanation of how Christ is truly present in the sacrament, while St Bonaventure is particularly remembered for helping believers to understand why Christ remains present among us: because, in his great love, he desires to unite himself ever more closely to those whom he loves.

The Eucharist is, above all, the sacrament of Christ's presence with us, transforming us and drawing us toward the heavenly communion for which we were created. St Bonaventure teaches that at the Last Supper Christ gave his Body and Blood as food and drink (Lignum Vitae 30), leaving the Church a lasting memorial of his saving love.

Is Mass boring?

St Thomas Aquinas taught that, in heaven, we will never exhaust the mystery and beauty of God [Summa Theologiae q12 a6]. That is a delightful thought. We may think of heaven, therefore, is not a static existence but an eternal participation in the inexhaustible richness of divine truth and love.

In the Eucharist we receive a foretaste of heaven as we join the heavenly assembly.  Could anything be more true, beautiful and better than the Mass on this side of eternity?

Not only is life always (for me, at least) interesting and exciting, if sometimes challenging and painful, but we can also look forward in Christian hope to an eternity of ever-deeper wonder, joy, and communion with God. As St Paul writes:

What no eye has seen, nor ear heard, nor the human heart conceived, what God has prepared for those who love him (1 Corinthians 2:9).

Standing with angels

 

St Gregory of Nazianzus(329-390), a close friend of St Basil the Great [see Yet another early witness to the Eucharist], is known in the East as Gregory the Theologian.  After studying with Basil in Athens, they returned to their native Cappadocia (now Eastern Turkey) to serve the Lord. It was during the time of the Arian heresy which refused the full divinity of Christ, Gregory was reluctantly consecrated bishop of Sasima, a small Cappadocian town. Following the death of his father, the bishop of Nazianzus, he briefly overseed that church. 

Later he became Archbishop of Constantinople, the most prestigious see in the East and second only to Rome in honour. He played a leading role at the First Ecumenical Council of Constantinople in 381 A.D. which completed the creed that we commonly call the Nicene Creed, often recited at the Sunday Eucharist by Catholics and Orthodox Christians.

What does the word Eucharist mean?

The Greek noun εὐχαριστία (eucharistia) comes from two words:

eu (εὖ), meaning 'well' or 'good';

charis (χάρις), meaning 'grace', 'favour', 'gratitude', or 'thanks'.

Together, they convey the meaning of grateful thanksgiving for God's gifts.

The psalmist declares (Ps 116):

A thanksgiving cup I will raise; I will call on the Lord's name.

To participate in Mass is to participate in a feast of joy. Behind the grey walls of distraction, doubt, and discouragement, there is the joy of the risen Christ, who comes to us under the appearances of bread and wine.

It is well to be here. We are truly blessed.
