In the Gospels' account of Jesus' resurrection, it says that he appeared to Mary Magdalene early in the morning (Mk. 16:9-10), to his disciples and to the other women also early in the morning. All these appearances happened on the day of his resurrection. There is no record of the Risen Christ meeting his mother Mary first.

A normal practice of the Passover was to slaughter the sacrificial lamb on the afternoon of 14 Nisan and ate it together at sunset of 15 Nisan.

These events showed that the conflict between Jesus and the religious leaders was heating up and would eventually lead to his passion and death.
