In the Roman Catholic Church, the moment when, during 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., the bread and wine are transformed into the body and blood of Jesus, the so-called transubstantiationThe conviction that during the Eucharist bread and wine really do change into the body and blood of Jesus Christ, without changing their outer characteristics (bread and wine). As a result, the consecrated host can be venerated as the Blessed Sacrament. The doctrine of transubstantiation has caused much controversy in church history and led to various separation movements (such as Protestantism)., by the pronouncement of the sacramental words.
