The Practical Significance of the Trinity

Tomorrow is Trinity Sunday, in which we acknowledge and celebrate one of the most distinctive theological tenets of the Christian faith.

Our confession that the Divine actually exists, and that we can know objectively true information about the Divine, distinguishes us from atheism and agnosticism. We distinguish ourselves from deism (as well as much of ancient pagan philosophy) by affirming that the Divine is a personal Being who continues to interact with the world He has created through revelation and miraculous acts.

However, we also classify ourselves differently from the pantheistic (or panentheistic) tendencies of Hinduism, Buddhism, and many current spiritual fads by affirming that the Divine is a transcendent Being who confronts all nature with His sovereign holiness. Finally, the Christian belief about God is at odds with Judaism and Islam in that, while we affirm God's unity, it is a unity that is expressed mysteriously in three distinct Persons: the Father, Son, and Holy Spirit.

As a theological doctrine, the Trinity has been grappled with for centuries. Specifically, we owe a debt of gratitude to the great Cappadocian Fathers of the Eastern Church (Basil the Great, Gregory of Nyssa, and Gregory of Nazianus) and Saint Augustine of the Western Church for their masterful attempts of expressing the life of the Trinity. Today we are seeing a remarkable renewal of trinitarian thought among both Protestant and Catholic theologians.

However, in honor of Trinity Sunday, I would just like to share a few brief thoughts I've been thinking about this doctrine's practical significance in the everyday life of the individual believer, and in the life of the Church:

First of all, the Doctrine of the Trinity reminds us that Ultimate Reality is relational in nature. The highest Truth in existence is not a static, bare fact to be analyzed or reasoned about: Ultimate Truth is the creative, dynamic interaction—the perichoresis—among the Father, Son, and Holy Spirit, who exist in intimate communion with one another.

Perhaps this should give us a clue as to how we should “package” the truths of our faith. While systematic theologies and rational apologetics serve an indispensable purpose as part of the package, Christians must understand that living out the truths of faith in intimate communion with others, and in a dynamic and creative way, is perhaps the best way to communicate truthfully the nature of the God we represent, worship, and serve.

Secondly, the Doctrine of the Trinity implies that unity and diversity need not be contradictory terms, but that they together give us a deep insight into the nature of truth and reality. The three Persons of the Trinity are clearly distinct; there is, therefore, diversity within the Godhead. At the same time, the Godhead is inseparably unified in essence and in purpose; thus, there is also unity.

This extraordinary fact of the Divine relationship may have something unique to say about human relationships as well, especially in the church. There are those Christian denominations that call for a unity that is almost “uniformity”—a situation that allows for no originality or creativity in communicating and living out our faith. At the other side of the spectrum are those who champion diversity at all costs, to the extent it is nearly impossible to acknowledge or articulate what truly unites us (the Gospel) without being labeled “offensive” or “doctrinaire.” Our Trinitarian God can be a model for us as we strive to acknowledge and celebrate the rich diversity that exists within the Christian community, while also unapologetically confessing a greater unity because of the reconciling work of Jesus Christ.

Finally, individual human beings (both male and female) are created in the Image of God (Genesis 1:27). As an individual I am a multi-faceted creature, and my identity cannot be reduced merely to my body, or my mind, or my emotions. All three constitute distinct parts of one being: me. As the Trinity is three distinct Persons in one God, I must strive to harmonize the distinct aspects of my personality into the single purpose of loving God and loving others (Mark 12:28-31).

Loving others, I must show respect for these different facets of personality in every person I meet. I can never view another human being as merely a body to be exploited, emotions to be manipulated, or a mind to be debated. I must view each human being as a whole person…as my neighbor…and as C. S. Lewis once aptly remarked, “Next to the blessed Sacrament itself, your neighbor is the holiest object presented to your senses” (C. S. Lewis, The Weight of Glory). May God daily grant me the ability to see His Trinitarian Image in my wife, my friends, my congregation members, and every person I meet, and may He give me the grace to love them as He loves them.
