I believe in one, holy, catholic and apostolic Church.
I confess one Baptism for the forgiveness of sins
and I look for the resurrection of the dead
and the life of the world to come. Amen.
Ending the liturgy of the Word are the general intercessions (the Prayer of the Faithful), in which petitions are commonly offered for the church, for the civil authorities, for those oppressed by various needs, for all humankind, and for the salvation of the entire world. Specific prayers may also be extended to couples recently married in the church, to persons ordained or confirmed in the church, or to members of the church suffering illness or bereavement. The liturgy of the Eucharist
The third part of mass, the liturgy of the Eucharist, is the high point of the celebration. While the gifts (donations) of the people are being gathered and brought to the altar, an offertory song is typically sung. Meanwhile, the deacon and assistants prepare the altar. The priest washes his hands, and he offers a prayer of thanks to God (quietly or aloud, if no song is being sung) for the gifts of bread and wine that presently will be changed into Christ’s body and blood. He then invites the people to pray that their sacrifice will be acceptable to God, whereupon the people repeat: "May the Lord accept the sacrifice at your hands for the praise and glory of his name, for our good, and the good of all his holy Church." The eucharistic prayer follows, in which the holiness of God is honoured, his servants are acknowledged, the Last Supper is recalled, and the bread and wine are consecrated. The host and chalice are then elevated into the air by the priest, who sings or recites: "Through him, with him, in him, in the unity of the Holy Spirit, all glory and honour is yours, almighty Father, forever and ever." The people respond with "Amen." The communion rite
At the start of the communion rite, the priest calls on the people to pray the most universal of Christian prayers—the Lord’s Prayer (the "Our Father," the Pater Noster)—whose author, according to the Gospels, was Christ himself. The prayer is said or sung, often while members of the congregation join hands: 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.
In divergence from Protestant practice, the Catholic church stops the prayer after "deliver us from evil," which is where the original prayer ended before an additional two lines (a doxology) were added about 100 ce. At this pause in the prayer the priest says, "Deliver us, Lord, from every evil, and grant us peace in our day…," at which point the people in unison complete the final two lines of the prayer, saying “For the kingdom, the power, and the glory are yours, now and forever.” The deacon then asks members of the congregation to exchange a sign of peace with their neighbours to signify one family in Christ, an act which usually consists of a handshake or a nod while saying "Peace" or "Peace be with you."
After the priest prepares the bread and wine, the people exclaim: "Lord, I am not worthy that you should enter under my roof, but only say the word and my soul shall be healed." Once the priest has administered Holy Communion to his assistants, the people then file up to the altar, row by row, receiving the bread first (which is placed in their hands or on their tongues by the priest, deacon, or eucharistic minister) and the chalice of wine, if offered, second. (Communion offered in both kinds—bread and wine—has a long and complicated history; beginning in the 12th century, the chalice gradually came to be reserved for the priest alone. Though Communion under both kinds is now allowable at the discretion of the bishop, many churches offer both kinds to the priest’s assistants at the altar but offer only the bread to the congregation at large; this is often done merely to ensure an "orderly" administering of Communion to the congregation, and the church teaches that the whole Christ is present in the individual elements of bread and wine.) Upon receiving Communion, the people then return to their seat and kneel in silent prayer while waiting for Communion to end. The concluding rite
Once Holy Communion is completed and the altar has been cleared, the final part of mass follows: the concluding rite. The priest, after a period of silence for reflection on the "mystery" that has just occurred, offers a final greeting. Church announcements are typically made at this point, a final blessing is then offered, and the people are dismissed, encouraged to "go in peace to love and serve the Lord." Variations on the dismissal include “The mass is ended, go in peace,” and “Go in the peace of Christ.” Some parishes sing a final song, though this is not required according to the official order of the mass. The role of the church in society Missions
From its beginnings, Christianity has regarded itself as a true world religion that appeals to all people without distinction of race, nation, or culture. Roman Catholics believe that their church has preserved this missionary thrust more faithfully than any of the non-Roman churches. During the 4th and 5th centuries the Roman church devoted itself to the evangelization of the various peoples who had begun to pressure and cross the frontier of the Roman Empire. Wishing to become “Roman,” these peoples accepted the church as a component of Roman civilization or at least recognized the power of the Christian God, as did the great Frankish king Clovis. Those who established themselves in the Western Roman Empire, notably the Anglo-Saxons and the Franks, became active missionaries after their conversion to Christianity, at times finding themselves in competition with missionaries from the Byzantine world.

After the year 1000, the growing awareness of Islam as a religious and political rival of Christianity led to the Crusades. The church’s response to Islam was not solely violent but included active missionary efforts by members of the Franciscan and Dominican orders; the most famous such mission was that of St. Francis during the Fifth Crusade.
The missionary movement received new stimulus during the two ages of European exploration and colonial expansion in the 16th and 17th centuries. Spanish and Portuguese monarchs included missionaries among the colonizers sent to the Americas, Africa, and Asia, and French merchant interests sponsored missionaries in areas that the French explored. In the 17th century, control of evangelical missions gradually passed from national political and economic leaders to the papacy. In the 19th century Rome assumed a much more central role in missionary work, defining missionary territories and assigning responsibility for them to various religious orders, and individual popes personally supported the missionaries and directed their evangelical efforts.
Missionary churches achieved the independence appropriate to the diocesan structure only in the 20th century, many at the time of Vatican II. Vatican II officially ended the colonial phase of missions and declared that “the whole Church is missionary, and the work of evangelization is a basic duty of the People of God.” Nevertheless, it was difficult for Roman Catholic missions to divorce themselves from colonialism, and many missionaries, it must be said, did not want the divorce. Until the mid-20th century, most of the clergy and all of the hierarchy in mission countries were European or American, as were the heads of educational and benevolent operations. Even the peoples of the mission countries, including their clergy and religious personnel, generally wished to give their church a European identity rather than an Asian or African one.
