Our religion is based on the Mystery of the Incardination. (Remember: A mystery is a truth that we cannot fully understand.) But, doing our best, we honor the one true God, while at the same time we honor the Son of God as he became fully human in the person of Jesus. Today’s Gospel speaks of the earthly mission of that God made man.
In Chapter Ten of the Gospel according to John Jesus said, “I came into the world as light.”
There Jesus was speaking not as God, but as God made man in the person of Jesus.
We might compare that with something that John wrote in verse four of Chapter One of his Gospel speaking of God the Son. There he wrote, “In him was life, and the life was the light of the world.”
In that verse in Chapter One of his Gospel John was speaking about the Second Person of the Trinity, the Word. Analytically, the Second Person of the Trinity can be compared to our sun. Just as every last bit of energy in our solar system comes from the sun, so all mental energy in the world comes from the Son.
