The Liturgy of the Word celebrates the word of God and we hear one to two readings from the Bible plus a Gospel reading. The readings are the same everywhere, but a parish could celebrate a special feast day and use those prescribed readings. Following the readings their is a homily. The homily is the sermon portion of the mass given by the Priest or Deacon. It is the segment of the service in which the Priest celebrating the mass discusses how the daily readings from the Bible relate to issues of the day and other moral and religious points he wishes to make.
The second part of the mass is the Liturgy of the Eucharist. This is the the part of Mass immediately following the prayer of the faithful where we celebrate the Lord’s sacrifice. During the Liturgy of the Eucharist we make offering to God; The priest re-enacts the Last Supper; the bread and wine are consecrated in the Eucharist and become the Most Precious Body and Blood of Christ. And we then receive the Eucharist.
This mass happens everywhere, every day in Catholic Churches through out the world. Having a universal Church is one of the greatest aspects of the Catholic Church. Where ever you go in the world you can attend mass and know that it is the same as it would be if you were at your local parish.
Sunday Mass is an important part of Roman Catholic life. All members are required to attend Mass on Sunday as a minimum participation in public worship.
