I like the story historians tell about the funeral of Charlemagne. Charlemagne was the greatest Christian ruler of the early Middle Ages. After his death a mighty funeral procession left his castle for the cathedral at Aix. When the royal casket arrived, with a lot of pomp and circumstance, it was met by the local bishop, who barred the cathedral door.
"Who comes?" the Bishop asked, as was the custom.
"Charlemagne, Lord and King of the Holy Roman Empire," proclaimed the Emperor's proud herald.
"Him I know not," the Bishop replied. "Who comes?"
The herald, a bit shaken, replied, "Charles the Great, a good and honest man of the earth."
"Him I know not," the Bishop said again. "Who comes?"
The herald, now completely crushed, responded, "Charles, a lowly sinner, who begs the gift of Christ."
To which the Bishop, Christ's representative, responded, "Enter! Receive Christ's gift of life!"
The point, of course, is that in God's eyes, we're all equally needy. Charlemagne, Mother Teresa, you and me. None of us will ever be "good enough" to force entrance into the presence of God.
