The Last Gospel
The Gospel for todays Mass is the opening verses of Johns Gospel (called the Prologue). It was often used as a blessing.
In the 13th century, it became the custom in some places for priests to recite this Gospel passage privately after Mass as they were taking off their vestments.
In the form of the Mass that emerged from the Council of Trent (late 16th century), the priest was to read this Gospel passage (to himself) at the altar before Mass ended.
In the liturgical reform of Vatican II, this private thanksgiving of the priest was no longer included as part of the Mass.
The first 18 verses of Johns Gospel are referred to as the Prologue. They deal with truths that soar far above the limits of human reason, and they are one of the reasons why John Is symbolized as an eagle.
It is Johns prologue that explicitly states what we mean by the term Incarnation: And the Word became flesh. This is one of the most basic truths of our faith.
We do not teach that Jesus was a good and holy man who, at some point in his life (e.g. his baptism, his death) was adopted by God and raised to divine status. Nor do we teach that Jesus was God wearing a human costume.
What we do teach is (take your time with this) that the eternally pre-existing Son of God (the Second Person of the Trinity), at a certain point in time, became a human being, born of a woman. Jesus is truly divine and truly human, and neither detracts from the fullness of the other. He did not simply become like us. He became one of us, a permanent member of the human family. And (this is the most important part of all) he did this so that as part of the human family and also Son of God, he could bring us into his own relationship to the Father.
This is what we celebrate at Christmas. And its something worth celebrating.
I heard it Christma Day. It's one of my favorites.
