The Mass, as you have pointed out is a celebration.

No, the Mass is a sacrifice. The sacrifice at Calvary. We are there to worship God, not to have a party.

No, the Mass is a sacrifice.

Are you sure? It would appear you disagree with the Church’s teaching authority. From the Catechism, formatting errors are mine:

ARTICLE 1
CELEBRATING THE CHURCH'S LITURGY
I. WHO CELEBRATES?
1136 Liturgy is an "action" of the whole Christ (Christus totus). Those who even now celebrate it without signs are already in the heavenly liturgy, where celebration is wholly communion and feast
The celebrants of the heavenly liturgy 1137 The book of Revelation of St. John, read in the Church's liturgy, first reveals to us, "A throne stood in heaven, with one seated on the throne": "the Lord God."¹ It then shows the Lamb, "standing, as though it had been slain": Christ crucified and risen, the one high priest of the true sanctuary, the same one "who offers and is offered, who gives and is given."² Finally it presents "the river of the water of life . . . flowing from the throne of God and of the Lamb," one of most beautiful symbols of the Holy Spirit.³
1138 "Recapitulated in Christ," these are the ones who take part in the service of the praise of God and the fulfillment of his plan: the heavenly powers, all creation (the four living beings), the servants of the Old and New Covenants (the twenty-four elders), the new People of God (the one hundred and forty-four thousand),⁴ especially the martyrs "slain for the word of God," and the all-holy Mother of God (the Woman), the Bride of the Lamb,⁵ and finally "a great multitude which no one could number, from every nation, from all tribes, and peoples and tongues."⁶
1139 It is in this eternal liturgy that the Spirit and the Church enable us to participate whenever we celebrate the mystery of salvation in the sacraments.

I. THE EUCHARIST - SOURCE AND SUMMIT OF ECCLESIAL LIFE
1324 The Eucharist is "the source and summit of the Christian life."¹³⁶ "The other sacraments, and indeed all ecclesiastical ministries and works of the apostolate, are bound up with the Eucharist and are oriented toward it. For in the blessed Eucharist is contained the whole spiritual good of the Church, namely Christ himself, our Pasch."¹³⁷
1325 "The Eucharist is the efficacious sign and sublime cause of that communion in the divine life and that unity of the People of God by which the Church is kept in being. It is the culmination both of God's action sanctifying the world in Christ and of the worship men offer to Christ and through him to the Father in the Holy Spirit."¹³⁸
1326 Finally, by the Eucharistic celebration we already unite ourselves with the heavenly liturgy and anticipate eternal life, when God will be all in all.¹³⁹
1327 In brief, the Eucharist is the sum and summary of our faith: "Our way of thinking is attuned to the Eucharist, and the Eucharist in turn confirms our way of thinking."¹⁴⁰

The sacrifice at Calvary. We are there to worship God, not to have a party.

This is true.

My last post wasn’t clear in the part from you I quoted. I was referring to your indication the Mass was not a celebration. I agree it is a Sacrafice:

The Mass, as you have pointed out is a celebration.
No, the Mass is a sacrifice.

Sorry for any confusion.

I would then suggest that you read the new Catholic Catechism. The Catholic Mass was, has been and is a celebration of the Last Supper, not a mournful acknowledgement of Calvary.
