During the daily Mass, a priest leads the congregation in the Lord's Prayer, followed by the rite of peace. He may read through the Roman missal and selected passages from the Bible. A priest will give thanks to Christ and lead the congregation in thanking God for the blessings of life. A priest also talks about how and why Christ instituted the Mass at the Last Supper.
At the Last Supper, Christ instituted Mass by surrendering his body and blood to God's will and delivering his body and blood to his apostles through the sharing of wine and bread. This is given to the congregation by the priest during the sacrament of unity, when the congregation is nourished by the priest through the word of God and the body of Christ.
After completing preparation for the Mass, the priest follows the structure of introductory rites, liturgy of the word, liturgy of the Eucharist and concluding rites. Mass may be performed once a day, twice on Sunday, three times on All Soul's Day, three times on Christmas, twice on Easter, twice on Holy Thursday and more frequently on any day with permission from Local Ordinary.
