The altar is the central piece of furniture used in the EucharistThis 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.. 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 priestIn the Roman Catholic Church, the priest is an unmarried man ordained as a priest by the bishop, which gives him the right to administer the six other sacraments: baptism, confirmation, confession, Eucharist, marriage, and the anointing of the sick. and the faithful gather around this table with bread and wine.
