Meditations on the Larger Catechism, pt. 9

How is the Trinity Vital for Me?
Back in 2005 America’s new “pastor,” Rick Warren, said, “The first Reformation was about doctrine; the second one needs to be about behavior. We need a reformation not of creeds but deeds. It’s time to stop debating the Bible and start doing it . . . This is the new reformation I’m praying for.” Sadly, what used to be a hallmark attitude of Protestant liberalism is now a pious platitude of so-called Bible-believing evangelicals that is fit for Hallmark. (The classic refutation of this that is so relevant today remains J. Gresham Machen's Christianity and Liberalism). To pit doctrine against duty, theology against community, faith against life is unbiblical. For example, Paul spoke of “the truth, which accords with godliness” (Titus 1:1). This is why our forefathers defined theology as, “Theology is the doctrine of living to God” (Ames, Medulla Theologica, 1.1). This is also unhelpful. How are we to live for God unless we know God? It’s the same in relationships. How can a husband and wife live and love unless they know each other? How can friends have a deep bond unless they know each other?
I say this because when it comes to the truth of the Holy Trinity, we say it is true, but we also say it is not “practical.” After all, how can the Trinity be of any use to me in my daily struggles in the Christian life? I want us to meditate on the question, How is the Trinity Vital for Me?
Adoring God’s Mystery
The Trinity is vital for me first and foremost because it brings me back to the basic Christian posture of adoring God’s mystery. We so often think, speak, and act as if we know God so well that we can then get busy with other things. The Triune nature of God reminds us that just to think of God’s oneness and his threeness is to enter into the deepest of Christian mysteries. When we think of the One, we are led to think of the Three; and when we think of the Three ,we are led to think of the One. This leads to adoration: “Holy, Holy, Holy is the LORD of hosts; the whole earth is full of his glory” (Isa. 6:3); “Holy, Holy, Holy, Lord God Almighty, who was and is and is to come” (Rev. 4:8).
What is this nature of God that causes adoration? In the words of the Larger Catechism, “How many persons are there in the Godhead?
There be three persons in the Godhead, the Father, the Son, and the Holy Ghost; and these three are one true, eternal God, the same in substance, equal in power and glory; although distinguished by their personal properties. (Q&A 9)
The one “Godhead” is Three, and these Three are One. Historically we have called this the “Trinity,” which comes from a Latin word, trinitas, meaning, “threeness.” The Trinity is a mystery in both senses of the word. It is a mystery because it is an incomprehensible, transcendent truth that only God himself knows fully. It is a mystery in the biblical sense of a truth that was hidden in shadows in the Old Testament, but is now exposed to the light of Jesus Christ in the New. This is why Augustine said, “In the Old [Testament] the New [Testament] is concealed, and in the New [Testament] the Old [Testament] is revealed" (Augustine, Quaestiones in Heptateuchum, 2.73).
The adorable mystery of our Triune God led the Puritan preacher, Thomas Watson, to say, “This is a divine riddle, where one makes three, and three makes one. Our narrow thoughts can no more comprehend the Trinity in Unity, than a nut-shell will hold all the water in a sea”(Watson, Body of Divinity, 109).
Knowing God’s Story
The vitality of the Trinity is also seen because it helps us in knowing God’s story. In reading and meditating on the Word of God, we come to know who God is in eternity and how he has acted in human history.
We come to know something of his own personal story in terms of how the Father, Son, and Holy Spirit relate to one another as the one true God. In the Larger Catechism we are asked, “What are the personal properties of the three persons in the Godhead? ” The answer: “It is proper to the Father to beget the Son, and to the Son to be begotten of the Father, and to the Holy Ghost to proceed from the Father and the Son from all eternity” (Q&A 10). God reveals himself to us in human terms—all the while communicating eternal realities and relationships—so that we earthly creatures can know him.
We also come to know in the Word his story in terms of how he relates to us. We confess with our forefathers in the wilderness that God is one: “Hear, O Israel: The LORD our God, the LORD is one” (Deut. 6:4). This one God’s name is placed upon us in Christian baptism, with mention of each of the persons: “Baptizing them in the name [oneness] of the Father, and of the Son, and of the Holy Spirit” (threeness) (Matt. 28:19).
Participating in God’s Community
This leads to another way in which the Trinity is vital for us. When we adore the Triune God and come to know him more in his Word, we are participating in God’s community. What does this mean?
First, because God is a Trinity fellowship with God is possible (John 10:14–15). We place a personal faith in a personal God, who has fellowship within the Godhead, and amazingly, with us.
Second, because God is a Trinity, worship is enjoying fellowship with a Trinitarian God (Matt. 28:19; Rev 4–5). Because there is one God, we the people of that God are to worship him alone. And when we worship the one God, we worship each Person of the Godhead equally.
Third, because God is a Trinity we share in fellowship with him as a community. The “let us make man” language of Genesis 1:26–27 resulted in those whom God created as being social beings. Besides fellowship with God, what higher fellowship can we have in this life than with our brothers and sisters in Christ?
So, this leads us back to where we started? Do we need a new Reformation? Yes. What kind of reformation do we need? Is it to be one not of doctrine but of behavior? Is it to be one not of creeds but deeds? What the church in our time needs most of all is an ever-deepening knowledge in head and heart of our classic doctrines so that we might live for the glory of God with more passion. What meditating on the doctrine of the Holy Trinity does is to lead us to a vital relationship with each Person, this proving the ancient Christian dictum, “theology is taught by God, teaches of God, and leads to God.”
