+ Mk 16: 9-15
When he had risen, early on the first day of the week, he appeared first to Mary Magdalene, out of whom he had driven seven demons.
She went and told his companions who were mourning and weeping.
When they heard that he was alive and had been seen by her, they did not believe.
After this he appeared in another form to two of them walking along on their way to the country.
They returned and told the others; but they did not believe them either.
(But) later, as the eleven were at table, he appeared to them and rebuked them for their unbelief and hardness of heart because they had not believed those who saw him after he had been raised.
He said to them, “Go into the whole world and proclaim the gospel to every creature.

643 Given all these testimonies, Christ’s Resurrection cannot be interpreted as something outside the physical order, and it is impossible not to acknowledge it as an historical fact. It is clear from the facts that the disciples’ faith was drastically put to the test by their master’s Passion and death on the cross, which he had foretold. The shock provoked by the Passion was so great that at least some of the disciples did not at once believe in the news of the Resurrection. Far from showing us a community seized by a mystical exaltation, the Gospels present us with disciples demoralized (“looking sad”) and frightened. For they had not believed the holy women returning from the tomb and had regarded their words as an “idle tale”. When Jesus reveals himself to the Eleven on Easter evening, “he upbraided them for their unbelief and hardness of heart, because they had not believed those who saw him after he had risen.”
1223 All the Old Covenant prefigurations find their fulfillment in Christ Jesus. He begins his public life after having himself baptized by St. John the Baptist in the Jordan. After his resurrection Christ gives this mission to his apostles: “Go therefore and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, teaching them to observe all that I have commanded you.”
