Parts of the Mass

Some essential vocabulary
Mass	From the Latin word, "missa," which means "sent." This word appears in the last thing said by the priest in Latin: "Ite, missa est," which may be understood to mean, "Go, you [the congregation] are sent."
Liturgy	From Greek, "laoi," people, and "ergon," work — "the work of the People of God." More loosely translated, the word refers to any form of public prayer in the Church.
Eucharist	From Greek, "eu," good, and "charis," gift. To say "good gift!" is to give thanks to the person from whom the gift has been received. The whole of the Mass is "thanks-giving" to God for all of the gifts He has given us.
Transubstantiation	At the consecration of the Mass, which is in the Eucharistic Prayer when the priest says, "This is my Body ... This is the chalice of my Blood," the substance of bread is changed entirely into the Body of Christ and the substance of wine is changed entirely into the Blood of Christ. This change takes place in the gifts that we place on the altar. Their trans-substantiation into the Body and Blood of Jesus changes them but does not change Jesus Himself. After the bread has become the Body of Christ and the wine has become the Blood of Christ, we called them "sacred species." What we do in eating the sacred species of bread and drinking the sacred species of wine does NOT injure Jesus in any way at all. The apostles received the sacred species at the Last Supper and saw with their own eyes that receiving the "Body, Blood, Soul, and Divinity" of Jesus did not cause Him any harm. The sacred species act on us to make us into sacred vessels. We cannot act on the sacred species to change the Body or Blood of Jesus in any way whatsoever.
"ex opere operato"	In all seven sacraments, Jesus acts directly and personally on the souls of His People. The priest is not a pipeline of grace, so that his sins and character defects cannot in any way prevent Jesus from baptizing, confirming, forgiving sin, giving us Himself under the appearance of bread and wine, uniting couples in marriage, ordaining deacons, priest, and bishops, or anointing the sick. Jesus uses the ministers of the sacraments as instruments but not as "channels" of grace.
Vestments, Sacred Vessels, Altar, and Tabernacle
Alb	Latin, alba, a white garment — derived from a Roman toga? The vestment is a reminder of Baptism and our need to be cleansed by God's grace.
Cincture	(some albs do not require cinctures) — a rope that functions like a belt and reminds the priest of the need for self-control.
Stole	A cloth band that goes over the shoulders of the priests. It is the distinctive sign of the office of the priest. Deacons have a different kind of stole.
Chasuble	Derived from Roman "overcoats." "Above all things, put on charity, which is the bond of perfection" (Col 3:14). Liturgical colors used for the stole and chasuble: White: resurrection; solemnities of the Lord; feasts and memorials of saints. Red: the color of blood; Passion and Death of Jesus; feasts and memorials of martyrs; Holy Spirit. Green: ordinary time, the largest part of the Church year, during which we study the things that Jesus said and did in the presence of His disciples. Purple: penitence and anticipation; Advent and Lent. Rose (pink): Gaudete Sundy in Advent and Laetare Sunday in Lent. Joy!
Chalice	The cup we use for the Blood of Christ.
Paten	The plate or bowl we use for the Body of Christ.
Ciborium	The covered vessel in which consecrated hosts are preserved in the Tabernacle.
Altar	Dual symbolism: - a raised platform for offering sacrifice, like the altar in the Holy of Holies in the Temple; - the Table of the Lord, like the Passover table, used to provide food and drink for the feast.
Tabernacle	From the Latin word for "tent," which is reminiscent of the Meeting Tent used by the People of God in their Exodus from Egypt and which, in turn, became the model for the Holy of Holies within the Temple in Jerusalem.
Missal	The book that the priest uses to say the Mass.
Lectionary	The book that contains the readings for the Mass.
A. The Introductory Rites — "beginning, introduction, and preparation."
Entrance procession
Introit verse or hymn
Sign of the Cross	"In the Name of the Father and of the Son and of the Holy Spirit." Touch your forehead, your heart, your left shoulder, and then your right shoulder in order to make "The Sign of the Cross."
Greeting
Act of Penitence	All of us are "sinners redeemed by grace." We should do a quick examination of conscience before Mass begins to think of where we need God's help the most today.
Kyrie	The original sacred language of Christianity was GREEK. "Kyrie eleison" means "Lord, have mercy." "Christe eleison" means "Christ have mercy."
Gloria	We worship Jesus as true God and true man.
Collect	Opening prayer. Varies with the season and the feast.
B. The Liturgy of the Word
Readings from Scripture	It is false that Catholics were ever forbidden to "read the Bible." We always have had readings from the Bible at Mass from the night of the Last Supper to tonight.
First Reading	From the Old or New Testament.
Responsorial Psalm	A “psalm” is a hymn, a song, or a poem. Usually from the Old Testament.
Second Reading	From the Old or New Testament. Weekday Masses and celebrations that are not solemnities usually do not have a Second Reading.
Gospel Acclamation
Gospel	We stand for the reading of the Gospel as a sign of special reverence because these readings put us so directly in touch with the words and deeds of Jesus Himself. Prayer of the priest before reading the Gospel "Cleanse my heart and my lips, Almighty God, that I may worthily proclaim your holy gospel." Action of the priest before reading the Gospel The priest makes a cross on the Gospel book, on his forehead, on his lips, and on his heart. Prayer of the priest as he kisses the Gospel after the reading "Through the words of the Gospel may our sins be wiped away."
Homily
Profession of Faith	The creed is a short statement of the essential dogmas of the faith. These dogmas help us to interpret the Scriptures correctly.
Prayer of the Faithful
C. The Liturgy of the Eucharist
Preparation of the Gifts	The priest pours a drop of water into the chalice, saying: "By the mystery of this water and wine may we come to share in the divinity of Christ who humbled himself to share in our humanity." After the chalice is blessed and placed on the altar, the priest prays: "With humble spirit and contrite heart may we be accepted by you, O Lord, and may our sacrifice in your sight this day be pleasing to you, Lord God."
Washing of hands	As water is poured over his fingers, the priest prays: "Wash me, O Lord, from my iniquity and cleanse me from my sin."
Orate, fratres	"Pray brothers and sisters that my sacrifice and yours may be acceptable to God, the almighty Father." The congregation is offering sacrifice, too. The whole Body of Christ is "a chosen people, a royal priesthood, a holy nation, God's special possession" (1 Peter 2:9).
Prayer over the Offerings
Preface	There are a very large number of prefaces that have been written for special seasons, solemnities, feasts, and memorials.
Sanctus
Eucharistic Prayer — "the center and summit of the entire celebration"	The various Eucharistic Prayers thank God for saving us through the death and resurrection of Jesus. All of them tell the story of the Last Supper, a Passover meal that Jesus shared with His disciples. In this ritual of the Old Testament ("Old Covenant"), Jesus initiated the New Testament ("New Covenant") and associated the gift of His Body and Blood as "real food ... real drink" (Jn 6:55) with the sacrifice that He was about to offer on the Cross. "Take this, all of you, and eat of it, for this is my Body, which will be given up for you." "Take this, all of your, 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." The consecration of the bread and wine takes place in this prayer. Jesus is our true High Priest. What was bread becomes His Body and what was wine becomes His Blood — by His priestly power. Jesus renews and extends the reality of the Last Supper and the reality of His sacrifice on the Cross in every Mass. Every member of the Body of Christ shares in the priesthood of believers. We are called to the self-offering of Jesus in the Mass by offering ourselves to Him in return. The action of Jesus is made visible and audible through the sacramental ministry of the priest; the priestly action of the whole Body of Christ in receiving Jesus and offering ourselves to the Father through Him is invisible and inaudible. It can only be seen through the eyes of faith.
Communion rite
Lord's Prayer	"Our Father ..."
Prayer for Deliverance from Evil	"Deliver us, Lord, from every evil ..."
Doxology	"For the Kingdom, the Power, and the Glory are Yours, now and forever" (1 Chronicles 29:10-13).
Breaking of the Bread (Fraction rite)
Commingling of the Body and Blood of Christ	The priests places a fragment of the host in the chalice and prays: "May this mingling of the Body and Blood of our Lord Jesus Christ bring eternal life to us who receive it."
Lamb of God
Rite of Peace
Non sum dignus	"I am not worthy that You should come under my roof" — but He does! God loves us because He is love, not because we have earned His love. His love is a grace, a gift freely given, that infinitely surpasses anything that we ever have accomplished or ever could accomplish. "God is love, and all who abide in love abide in God, and God in them" (1 Jn 4:16). Receive. Say thanks. Abide in love.
Reception of Communion	This is our "altar call." By going to the altar and saying "Amen," we are pledging our love to God and making a commitment to live in love with Him.
Communion antiphon or hymn
Prayer after Communion
Final blessing	Please make the Sign of the Cross when the priest gives the blessing.
Dismissal	"Go forth, the Mass is ended."
