A Beautiful Metaphor of Trinity

For my Theology II class we are reading a book called "Pneumatology", which is literally "the word about the Spirit". The book was highlighting the view of the Spirit of a few influential thinkers in Christian history, one of them being Catherine of Siena. I loved this imagery surrounding the Trinity.

"As a vidid poet, she [Catherine of Siena] employed unusually rich imagery. One of the most striking speaks of the Father as the table, the Son as the food, and the Holy Spirit as the servant, offering enlightenment and charity for souls and blazing desires for the church's reform."

This waiter carries to me [God the Father] their tender loving desires, and carries back to them the reward for their labors, the sweetness of my charity for their enjoyment and nourishment. So you see, I am their table, my Son is their food, and the Holy Spirit, who proceeds from the Father and from the Son, waits on them.
