The Trinity is not a math problem

RCIA (Rite of Christian Initiation of Adults) image posted by TeamRCIAAs evangelists and catechists, our number one job as catechumenate ministers is to bring people into intimacy and communion with Jesus Christ. That is impossible to do if we do not fully comprehend and teach that Jesus is part of a Holy Trinity.

The Catechism of the Catholic Church says that the truth of the Holy Trinity is at the very root of Christian living. That means that the mystery of the Trinity is not an esoteric philosophy for masters-level theology students. It is a lifestyle template for every Christian—from the youngest child to the eldest grandparents.

How the early church learned about “Trinity”

There is a misconception that the mystery of the Trinity is difficult to understand and therefore difficult to teach. We have to get past that. The “mystery” is no mystery in the sense of a puzzle. It is a mystery in the same way love is a mystery. We all understand love. The mystery of love is that it is a paradox—the more we give of ourselves to another, the more we receive; the more we unite ourselves to another, the more we become our true self. The Trinity is a mystery in the very same way.

But this understanding about the Trinity didn’t just come fully-formed from out of the sky. The early Christians had to reflect back on their relationship with Jesus the meaning of his resurrection.

TeamRCIA Webinar: Basic Theology for the RCIA Team

with Nick Wagner and Diana Macalintal

Give your team members a basic understanding of the central theology of Catholic faith. Theology is not an esoteric discipline reserved for people who live in academic towers. It is an everyday mystagogical reflection on our relationship with the Creator.

We will be discussing:

  • Why theology is important to you, your team, and the catechumens and candidates
  • What it means to “do theology”
  • How to understand some core theological teachings
    • Trinity
    • Grace
    • Hope
    • Salvation
  • What difference a Catholic theology makes for the world
Please join us for this webinar, and be sure to tell your friends and colleagues about it.

Date: Tuesday, December 4, 2012
Time: 2:00p to 3:00p Eastern Time / 11:00a to 12:00p Pacific Time

From these reflections, they realized that Jesus is the Christ or Messiah. They also realized that Jesus is Lord. A huge insight they got was that Jesus is the Word made flesh. And another was that Jesus is the Son of God. These are all things that became clearer to the church after the Resurrection.

Yet they also knew there could only be one God. So if Jesus is the Son of God—and also God—did that mean there are two Gods? For us in the 21st century, the answer is very clear, but our early ancestors in faith struggled with this dilemma for over 100 years. What was at stake was not merely a theological idea. The answer to this problem would determine who Christ was and what his relationship to us would be.

One person who tried to uphold the understanding that we worship one God alone was a priest in Egypt named Arius. He taught that God the Father created the Son and that there was a time when the Son was not. This meant that the Son was subordinate to the Father. It also meant that the Son was not God by nature, nor was he of the same essence as the Father.

However, Athanasius, the bishop of Alexandria, Egypt, had a bone to pick with Arius. Bishop Athanasius said that only God could save. And the way God saves us is by giving us a “share in the divine nature” (2 Peter 1:4). Therefore, if Christ saves us, then Christ is God—not a go-between, not a subordinate, but true God from true God.

The debate between Arius and Athanasius became so controversial that it threatened the unity of the Roman empire. So Constantine, the Roman emperor, called a council of all the bishops from all over the empire to settle the matter. That council was held in 325 in Nicea, from which we derive the Nicene Creed. Athanasius won the day, and so in the Creed, we say that the Son is one in being with the Father. Or in the new translation, we say that the Son is “consubstantial” (of one substance or essence) with the Father.

A love story

Yet all this still seems a bit academic. Where does the mystery of love come in?

The Eastern church can help us with this. Their insight is that the Trinity is an action we participate in. It is a dance between lovers so intimately bound to one another that if they stopped loving each other, they would lose their identity. And all creation is caught up into their dance and re-shaped into the deep mystery of their love.

To understand the Trinity then, we need look no further than our most intimate relationship with another person. Every time we give when we have nothing left, every time we forgive when there is no reason to—that is the mystery of the Trinity. It’s the human capacity to love and hope and create despite an unknown future.

From mystery to math

It was important at the time of Arius and Athanasius to come up with a very precise phrasing of what the church believes about Jesus so we could stop arguing and get back to worshipping as one, unified community of faith. However, we also paid a price for that.

Over the centuries, the theology of the Trinity became a specialty for those with deep theological training. For ordinary Christians, it became a complex math problem that my third-grade teacher summed up for as “a mystery that will be revealed to us in heaven.”

However, we cannot leave it at that. The mystery of the Trinity is not about math; it is about relationship. If we are going to have an intimate relationship with Jesus, and if Jesus is “consubstantial” with the Father, that means that we are also in an intimate relationship with the Father. We also have to understand that it is only through Jesus—through the Spirit of Jesus—that we are able to be reconciled to and become one with the Father.

This is the very heart of Jesus mission. It is not a mystery that will be revealed to us after we die. Jesus is the revelation, here and now.

God is love

As we are catechizing the catechumens and candidates, it is less important to focus on the math of the Trinity and more important to focus on the why. Why would God go to all the trouble of creating the world, creating us, and then sending the Son to save us? We arrive at the same answer as the early disciples. God is love. “God has no other reason for creating than his love and goodness: ‘Creatures came into existence when the key of love opened his hand’” (Catechism of the Catholic Church, 293). That is the mystery of the Trinity.

  1. As a former math teacher and now a DRE I had to read this cleverly titled post! Your explanation is perfect and so helpful to catechists. God has blessed you with a gift of words – to say it the right way! I recently had a Trinity and Christology class where we studied all of this in detail. Sometimes it gets a little heady, and I appreciate the simplicity of the truth that God creates in and out of love. The classic answer “because he loves us” is always true!

  2. Thanks for your comments Lisa. Here is a bit more about the contribution of the Eastern Church, which emphasizes your point that the Trinity is an act of love.

    In the early 4th century, Gregory of Nyssa and his theological companions, his brother Basil and their friend, Gregory, established how the Father is related to the Son and how they are related to the Spirit thus laying out a full doctrine of the Trinity.

    Building on the understanding that the Father and the Son are different beings yet one essence, they talked about the Trinity is a “perichoresis,” a circle dance.

    For Gregory and many of the Eastern mystics, the Trinity is not an equation but a dance—a relationship between persons, a right-ordering of creation. The principle characteristic of the Trinity is that the persons of the Trinity cannot exist without each other. Their bond creates such a deep community that they cannot exist without each other, nor can they exist without loving each other.

    The Trinity expresses the paradoxical religious truth that only in loving others and giving ourselves to others do we find ourselves and are able to be more of who we are meant to be.

    Blessings on all you do, and thanks for your commitment to this ministry!

  3. Thanks for this wonderful article. It has affirmed for my team and myself our presentation and on going discussion of the Trinity. Our underlying approach to the Trinity has been John’s statement, “God is Love”. From there we look at the interaction of the community of love that is present in the Trinity, and how we are included in that love.
    I appreciate your help and articles. Blessings, Sister Dianne Sehn, St. Anne’s Saskatoon, ?Sk. Canada

  4. Thanks Sr. Dianne! It sounds like you are doing great things in Saskatoon. Keep up the wonderful work.

  5. Hi Nick
    I enjoyed your presentation on the Trinity. As an additional resource I would recommend Frank Sheed’s book Theology and Sanity. His expaination of the trinity is one of the best I have read as it is geared for lay people not theologians.

  6. Nick and Diana, Thanks a lot for all you do for us who have been called to proclaim the GOOD NEWS of the RISEN CHRIST through the RCIA faith journey. You nailed it when you sum it up to LOVE. The unconditional love of God for us and the essence of our BEING. This is great. Thank you.
