The musical setting of the Eucharist is MISSA BREVIS IN D, K.194, BY W.A. MOZART, Sung by the choir of Bedford School.

The president and preacher is the Dean of Gloucester, The Very Reverend Andrew Zihni.

About the Eucharist

The Eucharist, which means 'thanksgiving', is perhaps the most important act of worship for Christians because it recalls the death and resurrection of Jesus, fulfilling his command at the Last Supper to remember him. Outwardly, the Eucharist takes the form of sharing bread and wine; inwardly, Christ is made present to us in a special way and we are given a taste of the heavenly banquet, which God has prepared for those who love him.

Today's service has four important elements. Firstly, the GATHERING draws the community together in the name of the Trinity, reminding us of our true identity as children of God. We then recall our failings in the Prayers of Penitence; this is an important part of our efforts to become more Christlike. We always do this in the certain knowledge that God forgives our sins, and this is made plain in the words of the absolution, given by the president. The Gloria in excelsis, a hymn of praise addressed to God, follows as a joyful response to God's mercy. The Collect brings this part of the service to a close, drawing everyone together in a special prayer, said in all churches across the world.

The LITURGY OF THE WORD invites us to engage with the words of Scripture and consider what they might mean in our own lives. The Gospel Reading is the high point of this part of the service, for in these words we hear of the life of Jesus. A sermon follows, which aims to assist us in our application of God's Word. The Prayers of Intercession then give us an opportunity to bring our concerns to God in the certain knowledge that God hears and answers prayer.

The LITURGY OF THE EUCHARIST begins with the Peace. In Matthew's Gospel, Jesus tells us that before we offer our gifts at the altar, we should be reconciled to one another, because the Eucharist is the meal which unites the Church. Then the altar is prepared for the Eucharistic Prayer, which is a thanksgiving for all that God has done in creation. The president then recalls the Last Supper, using the words of Jesus himself, thereby consecrating or making special the bread and wine. The congregation comes forward to receive communion or a blessing, which is followed by a prayer of thanksgiving.

The CONCLUSION brings the whole service to a close with a blessing and dismissal, reminding us that God is with us always and sends us out into the world so that others may come to know his love too.

The Gathering

At 10.15 a.m., the congregation stands to sing the processional hymn.

Hymn: At the name of Jesus

1. At the name of Jesus every knee shall bow, every tongue confess him King of glory now; 'tis the Father's pleasure we should call him Lord, who from the beginning was the mighty Word.
2. At his voice creation sprang at once to sight, all the angel faces, all the hosts of light, thrones and dominations, stars upon their way, all the heavenly orders, in their great array.
3. Humbled for a season, to receive a name from the lips of sinners, unto whom he came, faithfully he bore it spotless to the last, brought it back victorious, when from death he passed:
4. Name him, Christians, name him, with love as strong as death, but with awe and wonder and with bated breath: he is God the Saviour, he is Christ the Lord, ever to be worshipped, trusted, and adored.
5. Surely, this Lord Jesus shall return again, with his Father's glory, with his angel train; for all wreaths of empire meet upon his brow, and our hearts confess him King of glory now.

Words, Caroline M. Noel 1817-77. Tune, EVELYNS; W. H. Monk 1823-1889.

Prayers of Preparation

All Almighty God, to whom all hearts are open, all desires known, and from whom no secrets are hidden: cleanse the thoughts of our hearts by the inspiration of your Holy Spirit, that we may perfectly love you, and worthily magnify your holy name; through Christ our Lord. Amen.

Prayers of Penitence

The deacon says:

As we prepare to celebrate the presence of Christ in word and sacrament, let us call to mind and confess our sins.

All Almighty God, our heavenly Father, we have sinned against you and against our neighbour in thought and word and deed, through negligence, through weakness, through our own deliberate fault. We are truly sorry and repent of all our sins. For the sake of your Son Jesus Christ, who died for us, forgive us all that is past and grant that we may serve you in newness of life to the glory of your name. Amen.

The president says:

Almighty God, who forgives all who truly repent, have mercy upon you, + pardon and deliver you from all your sins, confirm and strengthen you in all goodness, and keep you in life eternal; through Jesus Christ our Lord.

All Amen.

Gloria in Excelsis

The Choir sings:

Gloria in excelsis Deo et in terra pax hominibus bonae voluntatis. Laudamus te, benedicimus te, adoramus te, glorificamus te, gratias agimus tibi propter magnam gloriam tuam.

Domine Deus, Rex cælestis, Deus Pater omnipotens. Domine Fili unigenite, Jesu Christe. Domine Deus, Agnus Dei, Filius Patris, qui tollis peccata mundi, miserere nobis, qui tollis peccata mundi, suscipe deprecationem nostram, qui sedes ad dexteram Patris, miserere nobis.

Quoniam tu solus sanctus, tu solus Dominus, tu solus altissimus, Jesu Christe, cum Sancto Spiritu in gloria Dei Patris. Amen.

Glory to God in the highest, and in earth peace, goodwill to all people. We praise you, we bless you, we worship you, we glorify you, we give thanks to you for your great glory.

Lord God, heavenly King, almighty God and Father, Lord Jesus Christ, the only-begotten Son, Lord God, Lamb of God, Son of the Father, who takes away the sins of the world, have mercy on us, who takes away the sins of the world, receive our prayer, who sits at the right hand of the Father, have mercy on us.

For you alone are the Holy One, you alone are the Lord, you alone are the Most High, Jesus Christ, with the Holy Spirit, in the glory of God the Father. Amen.

The Collect

The president introduces a period of silent prayer with the bidding:

Let us pray.

Silence is kept.

Almighty and everlasting God, by whose Spirit the whole body of the Church is governed and sanctified: hear our prayer which we offer for all your faithful people, that in their vocation and ministry they may serve you in holiness and truth to the glory of your name; through our Lord and Saviour Jesus Christ, who is alive and reigns with you, in the unity of the Holy Spirit, one God, now and for ever.

All Amen.

The congregation sits.

The Liturgy of the Word

New Testament Reading

A reading from Paul's letter to the Colossians.

He is the image of the invisible God, the firstborn of all creation; for in him all things in heaven and on earth were created, things visible and invisible, whether thrones or dominions or rulers or powers—all things have been created through him and for him. He himself is before all things, and in him all things hold together. He is the head of the body, the church; he is the beginning, the firstborn from the dead, so that he might come to have first place in everything. For in him all the fullness of God was pleased to dwell, and through him God was pleased to reconcile to himself all things, whether on earth or in heaven, by making peace through the blood of his cross.

And you who were once estranged and hostile in mind, doing evil deeds, he has now reconciled in his fleshly body through death, so as to present you holy and blameless and irreproachable before him- provided that you continue securely established and steadfast in the faith, without shifting from the hope promised by the gospel that you heard, which has been proclaimed to every creature under heaven. I, Paul, became a servant of this gospel.

I am now rejoicing in my sufferings for your sake, and in my flesh I am completing what is lacking in Christ's afflictions for the sake of his body, that is, the church. I became its servant according to God's commission that was given to me for you, to make the word of God fully known, the mystery that has been hidden throughout the ages and generations but has now been revealed to his saints. To them God chose to make known how great among the Gentiles are the riches of the glory of this mystery, which is Christ in you, the hope of glory. It is he whom we proclaim, warning everyone and teaching everyone in all wisdom, so that we may present everyone mature in Christ.

This is the word of the Lord.

All Thanks be to God.

(Colossians 1.15-28)

Hymn: Lord of all hopefulness

The congregation stands to sing:

Lord of all hopefulness, Lord of all joy, whose trust, ever child-like, no cares can destroy, be there at our waking, and give us, we pray, Your bliss in our hearts, Lord, at the break of the day.

Lord of all eagerness, Lord of all faith, whose strong hands were skilled at the plane and the lathe, be there at our labours, and give us, we pray, your strength in our hearts, Lord, at the noon of the day.

Lord of all kindliness, Lord of all grace, your hands swift to welcome, your arms to embrace, be there at our homing, and give us, we pray, your love in our hearts, Lord, at the eve of the day.

Lord of all gentleness, Lord of all calm, whose voice is contentment, whose presence is balm, be there at our sleeping, and give us, we pray, your peace in our hearts, Lord, at the end of the day.

Words, Jan Struther (Joyce Placzek) 1901-53. Tune, SLANE; Irish traditional melody harmonised by Erik Routley 1917-82.

Gospel Reading

The choir sings the acclamation and all repeat:

Alleluia. Alleluia. Alleluia.

Choir: Speak, Lord, for your servant is listening.

You have the words of eternal life.

All Alleluia. Alleluia. Alleluia.

When the Gospel is announced, the deacon says:

Hear the Gospel of our Lord Jesus Christ, according to Luke.

Glory to you, O Lord.

Now as they went on their way, he entered a certain village, where a woman named Martha welcomed him into her home. She had a sister named Mary, who sat at the Lord's feet and listened to what he was saying. But Martha was distracted by her many tasks; so she came to him and asked, 'Lord, do you not care that my sister has left me to do all the work by myself? Tell her then to help me.' But the Lord answered her, 'Martha, Martha, you are worried and distracted by many things; there is need of only one thing. Mary has chosen the better part, which will not be taken away from her.'

(Luke 10.38-end)

This is the Gospel of the Lord.

Praise to you, O Christ.

The congregation sits.

Sermon

The Creed

The congregation stands and the president says:

Let us declare our faith in God.

All We believe in one God, the Father, the Almighty, maker of heaven and earth, of all that is, seen and unseen. We believe in one Lord, Jesus Christ, the only Son of God, eternally begotten of the Father, God from God, Light from Light, true God from true God, begotten, not made, of one Being with the Father; through him all things were made. For us and for our salvation he came down from heaven, was incarnate from the Holy Spirit and the Virgin Mary and was made man. For our sake he was crucified under Pontius Pilate; he suffered death and was buried. On the third day he rose again in accordance with the Scriptures; he ascended into heaven and is seated at the right hand of the Father. He will come again in glory to judge the living and the dead, and his kingdom will have no end.

We believe in the Holy Spirit, the Lord, the giver of life, who proceeds from the Father and the Son, who with the Father and the Son is worshipped and glorified, who has spoken through the prophets. We believe in one holy catholic and apostolic Church. We acknowledge one baptism for the forgiveness of sins. We look for the resurrection of the dead, and the life of the world to come. Amen.

The Prayers of Intercession

The president says:

In the power of the Spirit, and in union with Christ, let us pray to the Father.

The congregation sits.

After each prayer, the response is used:

All hear our prayer.

At the end, the president says:

Merciful Father

All accept these prayers for the sake of your Son our Saviour Jesus Christ. Amen.

The Liturgy of the Sacrament

The Peace

The congregation stands.

The president introduces the Peace:

We are the body of Christ. In the one Spirit we were all baptized into one body. Let us then pursue all that makes for peace and builds up our common life.

The peace of the Lord be always with you.

All and also with you.

The deacon says:

Let us offer one another a sign of peace.

All may exchange a sign of peace.

(cf 1 Corinthians 12.13; Romans 14.19)

Preparation of the Table

Taking of the Bread and Wine

You can contribute to the ministry and mission of the Cathedral by using the Q.R. code, placing a cash gift in the collection plate after the service (in a Gift Aid envelope if possible), or using one of the contactless card machines.

As the altar is prepared, the congregation remains standing to sing the offertory hymn.

Hymn: Father of peace, and God of love

Father of peace, and God of love, we own thy power to save, that power by which our Shepherd rose victorious over the grave.

Him from the dead thou brought'st again, when, by his sacred blood, confirmed and sealed for evermore the eternal covenant stood.

O may thy Spirit seal our souls, and mould them to thy will, that our weak hearts no more may stray, but keep thy precepts still;

That to perfection's sacred height we nearer still may rise, and all we think, and all we do, be pleasing in thine eyes.

Words, Philip Doddridge 1702-51. Hebrews 13.20-21 as in Scottish Paraphrases 1781. Tune, CAITHNESS; Melody from Scottish Psalter 1635.

The Eucharistic Prayer

When the altar is prepared, the president says:

Blessed are you, Lord God of all creation: through your goodness, we have this bread to set before you, which earth has given and human hands have made. It will become for us the bread of life.

All Blessed be God for ever.

Blessed are you, Lord God of all creation: through your goodness, we have this wine to set before you, fruit of the vine and work of human hands. It will become for us the cup of salvation.

All Blessed be God for ever.

President: The Lord be with you.

All and also with you.

President: Lift up your hearts.

All We lift them to the Lord.

President: Let us give thanks to the Lord our God.

All It is right to give thanks and praise.

The president says:

Father, we give you thanks and praise through your beloved Son Jesus Christ, your living Word, through whom you have created all things; who was sent by you in your great goodness to be our Saviour. By the power of the Holy Spirit he took flesh; as your Son, born of the blessed Virgin, he lived on earth and went about among us; he opened wide his arms for us on the cross; he put an end to death by dying for us; and revealed the resurrection by rising to new life; so he fulfilled your will and won for you a holy people.

Therefore with angels and archangels, and with all the company of heaven, we proclaim your great and glorious name, for ever praising you and singing:

The choir sings:

Sanctus, Sanctus, Sanctus Dominus Deus Sabaoth. Pleni sunt cæli et terra gloria tua. Hosanna in excelsis. Benedictus qui venit in nomine Domini. Hosanna in excelsis.

Holy, holy, holy, Lord God of power and might, Heaven and earth are full of your glory. Hosanna in the highest. Blessed is he who comes in the name of the Lord. Hosanna in the highest.

Lord, you are holy indeed, the source of all holiness; grant that by the power of your Holy Spirit, and according to your holy will, these gifts of bread and wine may be to us the body and blood of our Lord Jesus Christ; who, in the same night that he was betrayed, took bread and gave you thanks; he broke it and gave it to his disciples, saying: TAKE, EAT; THIS IS MY BODY WHICH IS GIVEN FOR YOU; DO THIS IN REMEMBRANCE OF ME.

In the same way, after supper he took the cup and gave you thanks; he gave it to them, saying: DRINK THIS, ALL OF YOU; THIS IS MY BLOOD OF THE NEW COVENANT, WHICH IS SHED FOR YOU AND FOR MANY FOR THE FORGIVENESS OF SINS. DO THIS, AS OFTEN AS YOU DRINK IT, IN REMEMBRANCE OF ME.

Great is the mystery of faith:

Christ has died. Christ is risen. Christ will come again.

And so, Father, calling to mind his death on the cross, his perfect sacrifice made once for the sins of the whole world; rejoicing in his mighty resurrection and glorious ascension, and looking for his coming in glory, we celebrate this memorial of our redemption.

As we offer you this our sacrifice of praise and thanksgiving, we bring before you this bread and this cup and we thank you for counting us worthy to stand in your presence and serve you.

Send the Holy Spirit on your people and gather into one in your kingdom all who share this one bread and one cup, so that we, in the company of the Blessed Virgin Mary, Peter, Benedict, Kyneburga, and all the saints, may praise and glorify you for ever, through Jesus Christ our Lord; by whom, and with whom, and in whom, in the unity of the Holy Spirit, all honour and glory be yours, almighty Father, for ever and ever.

Amen.

The congregation sits.

The Lord's Prayer

Let us pray with confidence as our Saviour has taught us, each in our own language:

All Our Father, who art in heaven, hallowed be thy name; thy kingdom come; thy will be done; on earth as it is in heaven. Give us this day our daily bread. And forgive us our trespasses, as we forgive those who trespass against us. And lead us not into temptation; but deliver us from evil. For thine is the kingdom, the power and the glory, for ever and ever. Amen.

Breaking of the Bread

The president breaks the consecrated bread, saying:

We break this bread to share in the body of Christ.

All Though we are many, we are one body, because we all share in one bread.

Giving of Communion

The president says the invitation to communion:

Jesus is the Lamb of God who takes away the sin of the world. Blessed are those who are called to his supper.

All Lord, I am not worthy to receive you, but only say the word, and I shall be healed.

Agnus Dei

The Choir sings the Angus Dei:

Agnus Dei, qui tollis peccata mundi, miserere nobis.

O Lamb of God, you take away the sin of the world, have mercy on us.

Agnus Dei, qui tollis peccata mundi, miserere nobis.

O Lamb of God, you take away the sin of the world, have mercy on us.

Agnus Dei, qui tollis peccata mundi, dona nobis pacem.

O Lamb of God, you take away the sin of the world, grant us peace.

In the Cathedral, the president and people receive Communion.

If it is your custom to receive Communion in your own church, you are welcome to do so today. If you would rather receive a blessing, please bring this order of service with you so that we may know how to minister to you.

Communion is offered in both bread and wine, though you may wish to receive the bread only. For hygiene reasons, intinction (dipping the bread in the wine) is prohibited.

If you require a gluten free wafer, please tell the ministers.

Those watching the live stream may wish to use this prayer:

Lord Jesus, you made yourself known in the breaking of the bread, I love you above all things and I desire to receive you in my soul: since I cannot at this moment receive Communion, come at least spiritually into my heart; I embrace you as if you were already there and unite myself wholly to you, Never permit me to be separated from you. Amen.

The Choir sings the Communion motet:

O taste, and see, how gracious the Lord is : blest is the man that trusteth in him.

(Words, Psalm 34.8. Music, Ralph Vaughan Williams 1872–1958)

Prayer after Communion

The president introduces a period of silent prayer:

Let us pray.

Silence is kept.

Grant, O Lord, we beseech you, that the course of this world may be so peaceably ordered by your governance, that your Church may joyfully serve you in all godly quietness; through Jesus Christ our Lord.

All Amen.

All Almighty God, we thank you for feeding us with the body and blood of your Son Jesus Christ. Through him we offer you our souls and bodies to be a living sacrifice. Send us out in the power of your Spirit to live and work to your praise and glory. Amen.

The Dismissal

The congregation stands to sing:

Let us build a house where love can dwell and all can safely live, a place where saints and children tell how hearts learn to forgive; built of hopes and dreams and visions, rock of faith and vault of grace; here the love of Christ shall end divisions: All are welcome, all are welcome, all are welcome in this place.

Let us build a house where prophets speak, and words are strong and true, where all God's children dare to seek to dream God's reign anew. here the cross shall stand as witness and as symbol of God's grace; here as one we claim the faith of Jesus: all are welcome &c.

Let us build a house where love is found in water, wine and wheat: a banquet hall on holy ground where peace and justice meet. Here the love of God, through Jesus, is revealed in time and space, As we share in Christ the feast that frees us: all are welcome &c.

Let us build a house where hands will reach beyond the wood and stone to heal and strengthen, serve and teach, and live the Word they've known. Here the outcast and the stranger bear the image of God's face; let us bring an end to fear and danger: all are welcome &c.

Let us build a house where all are named, their songs and visions heard and loved and treasured, taught and claimed as words within the Word. Built of tears and cries and laughter, prayers of faith and songs of grace, let this house proclaim from floor to rafter: all are welcome &c.

(Words, Marty Haugen 1950-. Tune, TWO OAKS; Marty Haugen 1950-)

The Blessing

The president says:

The peace of God, which passes all understanding, keep your hearts and minds in the knowledge and love of God, and of his Son Jesus Christ our Lord; and the blessing of God almighty, + the Father, the Son, and the Holy Spirit, be among you and remain with you always.

All Amen.

The Dismissal
