The Holy Eucharist, the Church's sacrifice of praise and thanksgiving, has been celebrated in a variety of ways at different times and places. The name for the Eucharistic celebration has also varied. Some Eastern Christians call it the Divine Liturgy, others Holy Qurbana (Offering). Western Catholics usually call it Holy Mass. Despite the many differences, there are still basic elements of the Eucharistic celebration that are common in all its forms.On the day that is called Sunday we have a common assembly of all who live in the cities or in the outlying districts. The memoirs of the Apostles or the writings of the Prophets are read, as long as there is time. Then, when the reader has finished, he who presides over the assembly speaks to all present, challenging them and inviting them to follow the good things presented in the holy writings.

The main part of the Liturgy of the Word is composed of Scripture readings and chants. We listen to the readings and open our minds and hearts to what God offers us, especially through the Divine Eucharist. The Word of God in Scripture is God's message to us today.
