There exists a tradition which makes Mary Magdalene the originator of the custom of making red eggs at Easter. After the Ascension of Jesus, Mary Magdalene, called “the apostle to the apostles” because she brought the good news of the resurrection to the other apostles, wen to Rome to preach the Gospels there.
In Rome she had dinner with the emperor Tiberius to tell him what a mistake he had made by allowing Pontius Pilate to crucify Jesus. But, she told him, on the third day Jesus rose from the dead–conquering death for all. She held took up a white egg from the table to explain the new life in Jesus. Emperor Tiberius scoffed at her saying, “Your Lord could no more be raised from the dead than that egg your holding could turn red. At that moment the egg is Mary Magdalene’s hand turned red, reflecting the blood of Christ. She raised the red egg and said to Tiberius, “Christ is Risen!”
At this, Tiberius asked that Mary preach to them about Jesus and he and his whole household became followers of Jesus, believing because of her word and the miracle of the red egg. Forever after, whenever Mary began to preach, she would hold up a red egg.
