Trinity: The Preacher's Nightmare?

How does one describe a mystery? How does one define the undefinable? When it comes to the Most Holy Trinity that can easily be the case for the preacher. Each year when I get to this celebration I feel a mental block. What is something new that I can add to what I have said before? Nothing!

Father, the Creator. Son, the Redeemer. Holy Spirit, the Sanctifier. Okay, I knew that.

Father, the Lover. Son, the Beloved. Holy Spirit, the Love! Something novel? Perhaps.
But the important fact remains that we who are baptized into our Lord Jesus Christ share in that love. How truly blessed we are!
