This litany is based upon the Gospel reading for Trinity Sunday, Year B, the story of Nicodemus and his nighttime run on enlightenment. If you're looking for a litany more specifically geared toward Trinitarian themes, please see this one.
Christ, we hate to admit that we can identify with Nicodemus,
Who had a reputation to uphold;
So he came to visit you at night, through the back door; (1)
Burning with curiosity,
Hoping for enlightenment on the sly.
You know how secretly needy we are.
You are a leader of rascals and rebels,
Keeper of mysteries,
Able to reach over the laws of nature
And grab hold of the miraculous,
Pulling it into our here and now:
Miracles of healing and transcendence.
We are fascinated by you,
And a little confused.
We are humbled by you.
You teach us how little we know.
You are like a telescope,
Showing us the mysteries of heaven.
You are like a mirror,
Showing us our potential.
You seem to speak to us in riddles: To get to the end,
We must go back to the beginning.
To get to the Community of God
We must be re-born. (2)
Well, birth is a messy business,
A rite of passage for all.
Grant that we may participate in this mystery:
To be born of spirit
From the womb of heaven
Into the arms of heaven.
