+ Mk 8: 14-21
They had forgotten to bring bread, and they had only one loaf with them in the boat.
He enjoined them, “Watch out, guard against the leaven of the Pharisees and the leaven of Herod.”
They concluded among themselves that it was because they had no bread.
When he became aware of this he said to them, “Why do you conclude that it is because you have no bread? Do you not yet understand or comprehend? Are your hearts hardened?
Do you have eyes and not see, ears and not hear? And do you not remember,
when I broke the five loaves for the five thousand, how many wicker baskets full of fragments you picked up?” They answered him, “Twelve.”
“When I broke the seven loaves for the four thousand, how many full baskets of fragments did you pick up?” They answered (him), “Seven.”
He said to them, “Do you still not understand?”
The New American Bible
The Catechism of the Catholic Church
1329 The Lord’s Supper, because of its connection with the supper which the Lord took with his disciples on the eve of his Passion and because it anticipates the wedding feast of the Lamb in the heavenly Jerusalem.
The Breaking of Bread, because Jesus used this rite, part of a Jewish meal when as master of the table he blessed and distributed the bread, above all at the Last Supper. It is by this action that his disciples will recognize him after his Resurrection, and it is this expression that the first Christians will use to designate their Eucharistic assemblies; by doing so they signified that all who eat the one broken bread, Christ, enter into communion with him and form but one body in him.
The Eucharistic assembly (synaxis), because the Eucharist is celebrated amid the assembly of the faithful, the visible expression of the Church.
Saints Cyril and Methodius
Saints Cyril and Methodius (826-869, 815-885; Greek: Κύριλλος καὶ Μεθόδιος; Old Church Slavonic: Кѷриллъ и Меѳодїи more) were two brothers who were Byzantine Christian theologians and Christian missionaries. Through their work they influenced the cultural development of all Slavs, for which they received the title “Apostles to the Slavs”. They are credited with devising the Glagolitic alphabet, the first alphabet used to transcribe Old Church Slavonic. After their deaths, their pupils continued their missionary work among other Slavs. Both brothers are venerated in the Orthodox Church as saints with the title of “equal-to-apostles”. In 1880, Pope Leo XIII introduced their feast into the calendar of the Roman Catholic Church. In 1980, Pope John Paul II declared them co-patron saints of Europe, together with Benedict of Nursia.
