The liturgical celebration in which the Eucharist is central. It consists of two main parts: the Liturgy of the Word and the Liturgy of the Eucharist. The main parts of the Liturgy of the Word are the prayers for mercy, the Bible readings, and the homilyExplanation of the Scripture readings during the Mass.. The Liturgy of the Eucharist begins with the offertory, whereby bread and wine are placed on the altarThe altar is the central piece of furniture used in the Eucharist. Originally, an altar used to be a sacrificial table. This fits in with the theological view that Jesus sacrificed himself, through his death on the cross, to redeem mankind, as symbolically depicted in the painting "The Adoration of the Lamb" by the Van Eyck brothers. In modern times the altar is often described as "the table of the Lord". Here the altar refers to the table at which Jesus and his disciples were seated at the institution of the Eucharist during the Last Supper. Just as Jesus and his disciples did then, the priest and the faithful gather around this table with bread and wine.. This is followed by the EucharisticThis is the ritual that is the kernel of Mass, recalling what Jesus did the day before he died on the cross. On the evening of that day, Jesus celebrated the Jewish Passover with his disciples. After the meal, he took bread, broke it and gave it to his disciples, saying, "Take and eat. This is my body." Then he took the cup of wine, gave it to his disciples and said, "Drink from this. This is my blood." Then Jesus said, "Do this in remembrance of me." During the Eucharist, the priest repeats these words while breaking bread [in the form of a host] and holding up the chalice with wine. Through the connection between the broken bread and the "broken" Jesus on the cross, Jesus becomes tangibly present. At the same time, this event reminds us of the mission of every Christian: to be "broken bread" from which others can live. Prayer, during which the praise of God is sung, and the consecrationIn the Roman Catholic Church, the moment when, during the Eucharist, the bread and wine are transformed into the body and blood of Jesus, the so-called transubstantiation, by the pronouncement of the sacramental words. takes place. Fixed elements are also the praying of the Our FatherPriest who is a member of a religious order. and a wish for peace, and so one can symbolically sit down at the table with Jesus during CommunionThe consumption of consecrated bread and wine. Usually this is limited to eating the consecrated host.. Mass ends with a mission (the Latin missa, from which ‘Mass’ has been derived): the instruction to go out into the world in the same spirit.
