He rebuked them for their unbelief
... they had not believed those who saw him after he had been raised (Mk 16:14)
When Jesus 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."
