Taking each of the third mysteries we can see the divine being translated into the earthly:
Joyous: The birth of Christ - Where we see God take on a form that will function in this world.
Luminous: The Kingdom - This is the promise of a worldly society that will become divine in its characteristics.
Sorrowful: The Crown of Thorns - Here we see the form the heavenly crown takes in this world.
Glorious: Pentecost (or the Descent of the Holy Spirit) - Well, this is the most literal.
