From: Isaiah 55:1-3

Epilogue: Invitation to partake of the banquet of the Lord’s Covenant

[1] “Ho, every one who thirsts,
come to the waters;
and he who has no money,
come, buy and eat!
Come, buy wine and milk
without money and without price.
[2] Why do you spend your money for that which is not bread,
and your labour for that which does not satisfy?
Hearken diligently to me, and eat what is good,
and delight yourselves in fatness.
[3] lncline your ear, and come to me;
hear, that your soul may live;
and I will make with you an everlasting covenant,
my steadfast, sure love for David.

Commentary:

55:1-13. The invitation to the Covenant banquet acts as the epilogue to the second part of the book of Isaiah, and picks up on themes in chapter 40, which is its prologue. The two chapters help to give literary and thematic unity to this part of the book. The oracle in chapter 55 sums up in a way the teachings contained in the preceding chapters -- the invitation to the Covenant banquet (vv. 1-3), reminiscent of that celebrated by Moses at Mount Sinai (Ex 24:5, 11); the renewal of the Covenant with David on Zion (vv. 4-5); the transcendence of God, who is unaffected by the sins of men (vv. 8-9); the power of the word of God (vv. 10-11); and, as a final synthesis, the promise of a new exodus, a sign of God’s ever- lasting salvation.

These oracles are a call for conversion, a call to take advantage of the salvific gifts so generously offered: “Come to the waters” (v. 1), “Come to me” (v. 3), “Seek the Lord” (v. 6), “Let the wicked forsake his way” (v. 7). Originally, it was a call to those exiled in Babylon to return to Jerusalem; but it is a call that is made at all times, to everyone. The reference to an everlasting Covenant, in keeping with promises made to David (cf. v. 3), can be read by Christians as an invitation to share in the new and eternal Covenant sealed with the Blood of our Lord Jesus Christ, a pledge of salvation for all mankind. In the Eucharist, the banquet of the New Testament, the words of the prophet come true in the complete sense in the words spoken by our Lord when he instituted that sacrament: “Take and eat” (cf. v. 1) the true bread of life, the very finest food, which money cannot buy (vv. 1-3). Therefore, the invitation extended by the prophet is a call to Christians to partake of the Blessed Eucharist. Paul VI, urging the faithful to take part in the Sunday celebration of the Eucharist, wrote: “How could we fail to take part in this encounter, to partake of the banquet that Christ has lovingly prepared for us? Our participation should be dignified and filled with joy. Christ, crucified and glorified, comes among his disciples to draw them all into the power of his resurrection. It is the pinnacle, here on earth, of the Covenant of love between God and his people: the sign and source of Christian joy, the preparation for the eternal banquet in heaven” (Gaudete in Domino, 322). Verses 1-11, like 54:5-14, are read in the liturgy of the Easter Vigil, which celebrates Christ’s victory over sin and which invites the faithful to partake of the banquet of the Covenant sealed by his death and resurrection: “On the feasts of the Lord, when the faithful receive the Body of the Son, they pro- claim to one another the Good News that the first fruits of life have been given, as when the angel said to Mary Magdalene, ‘Christ is risen!’ Now too are life and resurrection conferred on whoever receives Christ” (Fanqith, Brevarium iuxta ritum Ecclesiae Antiochenae Syrorum, in Catechism of the Catholic Church, 1391).
