The word Mark uses for “transfiguration” is metamorphoses, the title of Ovid’s poem. In Mark’s use of this term, like his use of the word “gospel” to open his work, he wants us to see that Jesus is Lord and God, not Ceasar.
The Transfiguration shows us Jesus’ metamorphosis from an itinerant preacher and healer in Galilee into the fullness of his purpose and being as the Messianic Son of God to be crucified in Jerusalem as the ransom for many.
In Mark, the problem in the human condition is that we are overcome by those things that seek to pull us into non-existence (i.e. sin). Jesus’s mission is to restore us to the fullness of our creation. His mission is to eliminate and overcome those defects in spirit and body.
In Mark, Jesus is the one that does battle on our behalf against the spiritual hosts of wickedness to free us from this present evil age. Mark is apocalyptic. Jesus is the challenge to the dominion of evil.
In those jars, we have the Eucharistic wine that purifies the world of its sins. “Behold the Lamb of God who takes away the sins of the world.” John 1:29. Jesus is the good wine.
John is telling us that the world in the Resurrection is like a wedding feast where only the best wine is served and it never runs out. This is the opening scene of Jesus’ ministry where John tells us what the remainder of his gospel-story is about.
The question, however, is why does Jesus need to be baptized? Why would Jesus need to repent and be ritually cleansed?
In this disclosure of Jesus’ divinity, the Baptism harkens back to the Story of Creation in Genesis 1 and the story of Deliverance in Exodus 14.
In Advent, the Church looks both backward to the Nativity and forward to the Second Coming, and this dual perspective is shown in the Magi and their worship of Jesus.
Within this story, we remember and celebrate the first manifestation of Christ to the Gentiles (the Magi). This fulfills the promise that all the nations, not just Israel, will be blessed through him.
