Just as some Eastern fathers saw Christ’s human/divine nature as one dynamic unity, they also saw the Trinity as an Infinite Dynamic Flow. The Western Church tended to have a more static view of both Christ and the Trinity—more a mathematical conundrum than an invitation to new consciousness. In our attempts to explain the Trinitarian mystery, the Western Church overemphasized the individual names—Father, Son, and Holy Spirit—but not so much the quality of the relationships between them, which is where all the power and meaning lies! So, let’s not spend too much time arguing about the gender of the Three. The real and essential point is how the three “persons” relate to one another: infinite outpouring and infinite receiving.
The Mystery of God as Trinity invites us into full participation with God—a flow, a relationship, a waterwheel of always outpouring love. God is a verb much more than a noun. Some Christian mystics taught that all of creation is being taken back into this flow of eternal life, almost as if we are a “Fourth Person” of the Trinity, or as Jesus put it, “so that where I am you also may be” (John 14:3).
The Cappadocian Fathers of the fourth century first developed this theology, though they readily admitted the Trinity is a wonderful mystery that can never fully be understood with the rational mind, but can only be known through love, prayer, and suffering. Contemplation of God as Trinity was made-to-order to undercut the dualistic mind. This view of Trinity invites us to interactively experience God as transpersonal (“Father”), personal (“Christ”), and even impersonal (“Holy Spirit”)—all at once.
The Cappadocian teaching moved to the West but was not broadly communicated. We find an active Trinitarianism in many Catholic mystics (e.g., Meister Eckhart, Julian of Norwich, John of the Cross, Teresa of Ávila). Scottish theologian Richard of St. Victor (1110–1173) reflected this early theology. He taught at great length that for God to be truth, God had to be one; for God to be love, God had to be two; and for God to be joy, God had to be three! 
True Trinitarian theology offers the soul endless creativity—an open horizon. Trinitarian thinkers do not seem to have much interest in things like hell, punishment, or any notion of earning or losing. They are only overwhelmed by infinite abundance and flow.
Our supposed logic has to break down before we can comprehend the nature of the universe and the bare beginnings of the nature of God. Paraphrasing physicist Niels Bohr, the doctrine of the Trinity is saying that God is not only stranger than we think, but stranger than we can think. Perhaps much of the weakness of many Christian doctrines and dogmas is that we’ve tried to understand them with a logical or rational mind instead of through love, prayer, and participation itself. In the end, only lovers seem to know what is going on inside of God. To all others, God remains an impossible and distant secret, just like the galaxies.
