the boldness to pray

to the Comforter, as St Symeon the New Theologian, that great devotee of the Divine Beauty, exclaimed with unrivalled lyricism: 

Come, true light.

Come, eternal life.

Come, hidden mystery.

Come, unnameable treasure.

Come, reality beyond any speech.

Come, person beyond all comprehension.

Come, unceasing exultation.

Come, impenetrable light.

Come, unfailing hope of the saved.

Come, lifter up of the fallen.

Come, resurrection of the dead.

Come, Almighty, for Thou dost unceasingly create,
transfigure, and change all things by Thy will alone.

Come, invisible one that none can touch or feel.

Come, for Thy name fills our hearts with desire
and is always on our lips; but Who Thou art
and what Thy nature is, we cannot say or know.

Come, unique one in one.

Come, for Thou Thyself art the desire within me.

Come, my breath and my life.

Come, comfort of my lowly soul.

Come, my joy, my glory, mine unending delight.
