First of all, it should be clear that the Holy Sacrifice of the Mass is offered to God and to God alone, while the sacraments are primarily instituted for humanity, for the sanctification of souls. Therefore, quite logically, the celebrant is turned towards God, the Incarnate and Crucified God. As shepherd, he stands with the flock facing one direction: both face the heavenly kingdom. Churches were therefore almost always built with their orientation to the east, so that the altar was placed against the rising sun, which was considered to be the symbol of the resurrected and glorified Christ, above all in His Second Coming.
The word liturgy comes from a Greek term meaning "public work or work done on behalf of the people."
A work, then, done by an individual or a group was a liturgy on behalf of the larger community. All the worshipers are expected to participate actively in each liturgy, for this is holy "work," not entertainment or a spectator event. Every liturgical celebration is an action of Christ the High Priest and of his Mystical Body, which is the Church. It therefore requires the participation of the People of God in the work of God.
Liturgy is centered on the Holy Trinity. At every liturgy the action of worship is directed to the Father, from whom all blessings come, through the Son in the unity of the Holy Spirit. We praise the Father who first called us to be his people by sending us his Son as our Redeemer and giving us the Holy Spirit so that we can continue to gather, to remember what God has done for us, and to share in the blessings of salvation.
From the United States Catholic Catechism for Adults
The Eucharistic celebration always includes: the proclamation of the Word of God; thanksgiving to God the Father for all his benefits, above all the gift of his Son; the consecration of bread and wine; and participation in the liturgical banquet by receiving the Lord's body and blood. These elements constitute one single act of worship. CCC 1408
It is Christ himself, the eternal high priest of the New Covenant who, acting through the ministry of the priests, offers the Eucharistic sacrifice. and it is the same Christ, really present under the species of bread and wine, who is the offering of the Eucharistic sacrifice. Only validly ordained priests can preside at the Eucharist and consecrate the bread and the wine so that they become the Body and Blood of the Lord.
The essential signs of the Eucharistic sacrament are wheat bread and grape wine, on which the blessing of the Holy Spirit is invoked and the priest pronounces the words of consecration spoken by Jesus during the Last Supper: "This is my body which will be given up for you.... This is the cup of my blood...."
By the consecration the transubstantiation of the bread and wine into the Body and Blood of Christ is brought about. Under the consecrated species of bread and wine Christ himself, living and glorious, is present in a true, real, and substantial manner: his Body and his Blood, with his soul and his divinity. CCC 1410-1413
Jesus Christ is entirely present in the host as well as in the chalice, because, in the Eucharist, He is living and immortal as in Heaven. Consequently, where His body is, so also is His blood, His soul, and His divinity; and where His Blood is, there also is His Body, His soul, and His divinity.
When Jesus Christ is in the host, He does not cease to be in Heaven, but He can be found at the same time in Heaven and in the most Holy Sacrament, in each consecrated host. When the priest splits a host, he does not split the Body of Jesus Christ, but only the species of bread, because the Body of Christ remains completely entire in all the parts into which the host is divided. Each piece must be honored and respected, adored by everyone, because it truly, really, and substantially contains Our Lord Jesus Christ.
This, as it is written in the Gospel of St. John, “Having loved His own who were in the world, He loved them unto the end” (Jn. 13:1), that is, in instituting the Holy Eucharist, Our Lord showed them His infinite love. Indeed, after having instituted the sacrament of His love, Christ wanted to be delivered into the hands of the Jews and the rabble of soldiers, to suffer His Passion before dying on the Cross, thus offering the unique and eternal sacrifice, alone capable of reconciling us with God, of redeeming us from our sins, and of delivering us from the power of the devil and opening to us the gates of Heaven.
