There are dozens of options available for the particular feasts and liturgical seasons.
It is truly right and just, our duty and salvation, always and everywhere to give you thanks, Father most holy, through your beloved Son, Jesus Christ, your Word through whom you made all things, whom you sent as our Savior and Redeemer, incarnate by the Holy Spirit and born of the Virgin. Fulfilling your will and gaining for you a holy people, he stretched out his hands as he endured his Passion, so as to break the bonds of death and manifest the resurrection. And so, with the Angels and all the Saints we declare your glory, as with one voice we acclaim:
To you, therefore, most merciful Father, we make humble prayer and petition through Jesus Christ, your Son, our Lord: that you accept and bless ✝ these gifts, these offerings, these holy and unblemished sacrifices, which we offer you firstly for your holy catholic Church. Be pleased to grant her peace, to guard, unite and govern her throughout the whole world, together with your servant N. our Pope and N. our Bishop, and all those who, holding to the truth, hand on the catholic and apostolic faith.
Remember, Lord, your servants (N. and N.) and all gathered here, whose faith and devotion are known to you. For them, we offer you this sacrifice of praise or they offer it for themselves and all who are dear to them, for the redemption of their souls, in hope of health and well-being, and paying their homage to you, the eternal God, living and true.
* In communion with those whose memory we venerate, especially the glorious ever-Virgin Mary, Mother of our God and Lord, Jesus Christ, and blessed Joseph, her Spouse, your blessed Apostles and Martyrs, Peter and Paul, Andrew, (James, John, Thomas, James, Philip, Bartholomew, Matthew, Simon and Jude: Linus, Cletus, Clement, Sixtus, Cornelius, Cyprian, Lawrence, Chrysogonus, John and Paul, Cosmas and Damian) and all your Saints: we ask that through their merits and prayers, in all things we may be defended by your protecting help. (Through Christ our Lord. Amen.)
** Therefore, Lord, we pray: graciously accept this oblation of our service, that of your whole family; order our days in your peace, and command that we be delivered from eternal damnation and counted among the flock of those you have chosen. (Through Christ our Lord. Amen.)
Be pleased, O God, we pray, to bless, acknowledge, and approve this offering in every respect; make it spiritual and acceptable, so that it may become for us the Body ✝ and Blood of your most beloved Son, our Lord Jesus Christ.
On the day before he was to suffer he took bread in his holy and venerable hands, and with eyes raised to heaven to you, O God, his almighty Father, giving you thanks he said the blessing, broke the bread and gave it to his disciples, saying: TAKE THIS, ALL OF YOU, AND EAT OF IT: FOR THIS IS MY BODY WHICH WILL BE GIVEN UP FOR YOU.
In a similar way, when supper was ended, he took this precious chalice in his holy and venerable hands, and once more giving you thanks, he said the blessing and gave the chalice to his disciples, saying: TAKE THIS, ALL OF YOU, AND DRINK FROM IT: FOR THIS IS THE CHALICE OF MY BLOOD, THE BLOOD OF THE NEW AND ETERNAL COVENANT, WHICH WILL BE POURED OUT FOR YOU AND FOR MANY FOR THE FORGIVENESS OF SINS. DO THIS IN MEMORY OF ME.
You are indeed Holy, O Lord, the fount of all holiness.
Make holy, therefore, these gifts, we pray, by sending down your Spirit upon them like the dewfall, so that they may become for us the Body ✝ and Blood of our Lord, Jesus Christ.
At the time he was betrayed and entered willingly into his Passion, he took bread and, giving thanks, broke it, and gave it to his disciples, saying: TAKE THIS, ALL OF YOU, AND EAT OF IT: FOR THIS IS MY BODY WHICH WILL BE GIVEN UP FOR YOU.
In a similar way, when supper was ended, he took the chalice and, once more giving thanks, he gave it to his disciples, saying: TAKE THIS, ALL OF YOU, AND DRINK FROM IT: FOR THIS IS THE CHALICE OF MY BLOOD, THE BLOOD OF THE NEW AND ETERNAL COVENANT, WHICH WILL BE POURED OUT FOR YOU AND FOR MANY FOR THE FORGIVENESS OF SINS. DO THIS IN MEMORY OF ME.
You are indeed Holy, O Lord, and all you have created rightly gives you praise, for through your Son our Lord Jesus Christ, by the power and working of the Holy Spirit, you give life to all things and make them holy, and you never cease to gather a people to yourself, so that from the rising of the sun to its setting a pure sacrifice may be offered to your name.
Therefore, O Lord, we humbly implore you: by the same Spirit graciously make holy these gifts we have brought to you for consecration, that they may become the Body ✝ and Blood of your Son our Lord Jesus Christ at whose command we celebrate these mysteries.
For on the night he was betrayed he himself took bread, and giving you thanks he said the blessing, broke the bread and gave it to his disciples, saying: TAKE THIS, ALL OF YOU, AND EAT OF IT: FOR THIS IS MY BODY WHICH WILL BE GIVEN UP FOR YOU.
In a similar way, when supper was ended, he took the chalice, and giving you thanks he said the blessing, and gave the chalice to his disciples, saying: TAKE THIS, ALL OF YOU, AND DRINK FROM IT: FOR THIS IS THE CHALICE OF MY BLOOD, THE BLOOD OF THE NEW AND ETERNAL COVENANT; WHICH WILL BE POURED OUT FOR YOU AND FOR MANY FOR THE FORGIVENESS OF SINS. DO THIS IN MEMORY OF ME.
We give you praise, Father most holy, for you are great, and you have fashioned all your works in wisdom and in love. You formed man in your own image and entrusted the whole world to his care, so that in serving you alone, the Creator, he might have dominion over all creatures.
And when through disobedience he had lost your friendship, you did not abandon him to the domain of death. For you came in mercy to the aid of all, so that those who seek might find you. Time and again you offered them covenants and through the prophets taught them to look forward to salvation.
And you so loved the world, Father most holy, that in the fullness of time you sent your Only Begotten Son to be our Savior. Made incarnate by the Holy Spirit and born of the Virgin Mary, he shared our human nature in all things but sin. To the poor he proclaimed the good news of salvation, to prisoners, freedom, and to the sorrowful of heart, joy.
To accomplish your plan, he gave himself up to death, and, rising from the dead, he destroyed death and restored life. And that we might live no longer for ourselves but for him who died and rose again for us, he sent the Holy Spirit from you, Father, as the first fruits for those who believe, so that, bringing to perfection his work in the world, he might sanctify creation to the full.
Therefore, O Lord, we pray: may this same Holy Spirit graciously sanctify these offerings, that they may become the Body ✝ and Blood of our Lord Jesus Christ for the celebration of this great mystery, which he himself left us as an eternal covenant.
For when the hour had come for him to be glorified by you, Father most holy, having loved his own who were in the world, he loved them to the end: and while they were at supper, he took bread, blessed and broke it, and gave it to his disciples, saying, TAKE THIS, ALL OF YOU, AND EAT OF IT: FOR THIS IS MY BODY WHICH WILL BE GIVEN UP FOR YOU.
In a similar way, taking the chalice filled with the fruit of the vine, he gave thanks, and gave the chalice to his disciples, saying: TAKE THIS, ALL OF YOU, AND DRINK FROM IT: FOR THIS IS THE CHALICE OF MY BLOOD, THE BLOOD OF THE NEW AND ETERNAL COVENANT; WHICH WILL BE POURED OUT FOR YOU AND FOR MANY FOR THE FORGIVENESS OF SINS. DO THIS IN MEMORY OF ME.
Therefore, O Lord, as we celebrate the memorial of the blessed Passion, the Resurrection from the dead, and the glorious Ascension into heaven of Christ, your Son, our Lord, we, your servants and your holy people, offer to your glorious majesty, from the gifts that you have given us, this pure victim, this holy victim, this spotless victim, the holy Bread of eternal life and the Chalice of everlasting salvation.
Be pleased to look upon these offerings with a serene and kindly countenance, and to accept them, as once you were pleased to accept the gifts of your servant Abel the just, the sacrifice of Abraham, our father in faith, and the offering of your high priest Melchizedek, a holy sacrifice, a spotless victim.
In humble prayer we ask you, almighty God: command that these gifts be borne by the hands of your holy Angel to your altar on high in the sight of your divine majesty, so that all of us who through this participation at the altar receive the most holy Body and Blood of your Son may be filled with every grace and heavenly blessing. (Through Christ our Lord. Amen.)
Remember also, Lord, your servants (N. and N.), who have gone before us with the sign of faith and rest in the sleep of peace. Grant them, O Lord, we pray, and all who sleep in Christ, a place of refreshment, light, and peace. (Through Christ our Lord. Amen.)
To us, also, your servants, who, though sinners, hope in your abundant mercies, graciously grant some share and fellowship with your holy Apostles and Martyrs: with John the Baptist, Stephen, Matthias, Barnabas, (Ignatius, Alexander, Marcellinus, Peter, Felicity, Perpetua, Agatha, Lucy, Agnes, Cecilia, Anastasia) and all your Saints: admit us, we beseech you, into their company, not weighing our merits, but granting us your pardon, through Christ our Lord.
Through whom you continue to make all these good things, O Lord; you sanctify them, fill them with life, bless them, and bestow them upon us.
Therefore, as we celebrate the memorial of his Death and Resurrection, we offer you, Lord, the Bread of life and the Chalice of salvation, giving thanks that you have held us worthy to be in your presence and minister to you.
Humbly we pray that, partaking of the Body and Blood of Christ, we may be gathered into one by the Holy Spirit.
Remember, Lord, your Church, spread throughout the world, and bring her to the fullness of charity, together with N. our Pope and N. our Bishop and all the clergy. [In Masses for the Dead: Remember your servant N., whom you have called (today) from this world to yourself. Grant that he (she) who was united with your Son in a death like his, may also be one with him in his Resurrection.]
Remember also our brothers and sisters who have fallen asleep in the hope of the resurrection and all who have died in your mercy: welcome them into the light of your face. Have mercy on us all, we pray, that with the blessed Virgin Mary, Mother of God, with blessed Joseph, her Spouse, with the blessed Apostles, and all the Saints who have pleased you throughout the ages, we may merit to be co-heirs to eternal life, and may praise and glorify you through your Son, Jesus Christ.
Therefore, O Lord, we celebrate the memorial of the saving Passion of your Son, his wondrous Resurrection and Ascension into heaven, and as we look forward to his second coming, we offer you in thanksgiving this holy and living sacrifice.
Look, we pray, upon the oblation of your Church, and, recognizing the sacrificial Victim by whose death you willed to reconcile us to yourself, grant that we, who are nourished by the Body and Blood of your Son and filled with his Holy Spirit, may become one body, one spirit in Christ.
May he make of us an eternal offering to you, so that we may obtain an inheritance with your elect, especially with the most blessed Virgin Mary, Mother of God, with blessed Joseph, her Spouse, with your blessed Apostles and glorious Martyrs (with Saint N.: the Saint of the day or Patron Saint) and with all the Saints, on whose constant intercession in your presence we rely for unfailing help.
May this Sacrifice of our reconciliation, we pray, O Lord, advance the peace and salvation of all the world. Be pleased to confirm in faith and charity your pilgrim Church on earth, with your servant N. our Pope and N. our Bishop, the Order of Bishops, all the clergy, and the entire people you have gained for your own. Listen graciously to the prayers of this family, whom you have summoned before you: in your compassion, O merciful Father, gather to yourself all your children scattered throughout the world.
[Normally, when not a mass for the dead] To our departed brothers and sisters and to all who were pleasing to you at their passing from this life, give kind admittance to your kingdom. There we hope to enjoy for ever the fullness of your glory through Christ our Lord through whom you bestow on the world all that is good.
[When this is a mass for the dead] Remember your servant N. whom you have called (today) from this world to yourself. Grant that he (she) who was united with your Son in a death like his, may also be one with him in his Resurrection, when from the earth he will raise up in the flesh those who have died, and transform our lowly body after the pattern of his own glorious body. To our departed brothers and sisters, too, and to all who were pleasing to you at their passing from this life, give kind admittance into your kingdom. There we hope to enjoy for ever the fullness of your glory, when you will wipe away every tear from our eyes. For seeing you, our God, as you are, we shall be like you for all the ages and praise you without end, through Christ our Lord, through whom you bestow in the world all that is good.
Therefore, O Lord, as we now celebrate the memorial of our redemption, we remember Christ's death and his descent to the realm of the dead; we proclaim his Resurrection and his Ascension to your right hand; and as we await his coming in glory, we offer you his Body and Blood, the sacrifice acceptable to you which brings salvation to the whole world.
Look, O Lord, upon the Sacrifice which you yourself have provided for your Church, and grant in your loving kindness to all who partake of this one Bread and one Chalice that, gathered into one body by the Holy Spirit, they may truly become a living sacrifice in Christ to the praise of your glory.
Therefore, Lord, remember now all for whom we make this sacrifice: especially your servant, N. our Pope, N. our Bishop, and the whole Order of Bishops, all the clergy, those who take part in this offering, those gathered here before you, your entire people, and all who seek you with a sincere heart.
Remember also those who have died in the peace of your Christ and all the dead, whose faith you alone have known. To all of us, your children, grant, O merciful Father, that we may enter into a heavenly inheritance with the blessed Virgin Mary, Mother of God, with blessed Joseph, her Spouse, and with your Apostles and Saints in your kingdom. There, with the whole of creation, freed from the corruption of sin and death, may we glorify you through Christ our Lord, through whom you bestow on the world all that is good.
