The Biblical revelation of Trinity is glorious, enriching, and captivating. The nineteenth century Baptist preacher C.H. Spurgeon once noted this about the study of God:
"No subject of contemplation will tend more to humble the mind, than thoughts of God. We shall be obliged to feel—
'Great God, how infinite art thou,
What worthless worms are we!'
But while the subject humbles the mind it also expands it. He who often thinks of God, will have a larger mind than the man who simply plods around this narrow globe."
Spurgeon later then states:
"I dare say it does, but after all, the most excellent study for expanding the soul, is the science of Christ, and him crucified, and the knowledge of the Godhead in the glorious Trinity."
What I want to do is to offer a brief, simple outline for starting to think about the Biblical doctrine of the Trinity. In the next several weeks I'll be leading a Wednesday night study on this subject. I intend to do this study of the Trinity in four sessions. As I have prayed and contemplated this important truth throughout the years on this blogsite, in our recent Nicene Creed blog series, and in sermons, I find I can never exhaust it. With that said, my intent in today's post and the next several is to give four pairs of truths whereby the reader can at least begin to consider this core truth of the Christian faith.
Truth Pair #1 God's oneness of being and plurality of Personhood.
Scripture reveals that God is one God or what is referred to as "monotheism" (for instance, Deuteronomy 6:4-5; Matthew 22:37-39). Yet we also see at the same time reference to a plurality of personhood that gradually is revealed more and more as one goes from Old Testament to New Testament (for example, Proverbs 30:4; 1 Corinthians 8:6; Acts 5:3-4).
Truth Pair #2 God the Father's eternal act of begetting and God the Son being eternally begotten.
Not only do we see that first pair of truths concerning God's oneness of being and plurality of personhood revealed, but we also see the Scriptures saying quite a bit about the eternal relationship of the Father and the Son. Their co-equality and sharing of the Divine nature is stressed again and again (for example, Psalm 2:7; John 1:1-3; John 10:30; 1 Corinthians 8:6).
What the Bible does is help us to know how we can distinguish between the Father and the Son, since they are co-equal, co-eternal, and are truly God in unity and as Divine Persons. The term the Bible uses to describe the relationship of the Father and the Son is that the Son is "begotten" and the Father "begets" (for example Psalm 2:7; John 3:16). Historic Christian creeds such as the Apostle's Creed, Nicene Creed, and Athanasian Creed give summaries of what the Bible means by the Son being the only begotten and the Father's eternal act of begetting Him.
Confession of Christ's deity is an on-ramp to the doctrine of the Trinity, since on the one hand the Bible asserts the deity of the Father as the One God of Israel in the Old Testament (see Deuteronomy 32:6) and reveals the deity of Jesus Christ in the New Testament (for instance, John 1:1-2, 8:58).
Truth Pair #3 God the Father and the Son's eternal out-breathing of the Holy Spirit and the Holy Spirit's procession from the Father and the Son.
In this third pair of truths, we come to another on-ramp into the discussion of the Trinity, namely how the Holy Spirit is a Person (the "He" pronouns used by Jesus to describe Him in John 16:8-12), as much God as the Father and the Son (Genesis 1:2), and how He relates to them and they to Him ("Spirit of Christ", Galatians 4:6; "Spirit of God", Ephesians 4:30).
Scripture tells us that the eternal relationship of the Father and the Son to the Holy Spirit is described in terms of the Spirit "proceeding" from the Father and the Son (see for example John 14:26-27; John 15:26-27). His very name "Spirit" also reveals that He is eternally "breathed out" by the Father and the Son (for example Psalm 104:30; John 20:22).
Truth Pair #4 The Trinity in unity and the unity in Trinity.
This final pair of truths will aim to bring the study back around to what we affirmed in the first point. I borrow this phrasing from the Athanasian Creed, which near its beginning and its middle says the following:
"And the catholic faith is this: That we worship one God in Trinity, and Trinity in Unity,"
That's how the Creed starts, noting that the term "Catholic" is not referring to the Roman Catholic Church but rather as a Greek word ("kathilikos"), Catholic means "universal" or "the church every place, everywhere". Then, the Athanasian Creed has a its central affirmation:
"So that in all things, as aforesaid, the Unity in Trinity and the Trinity in Unity is to be worshipped."
When our Lord Jesus Christ was preparing to ascend into Heaven, He gave His disciples final instructions. In Matthew 28:18-19 we see the famous "Great Commission" passage:
"Go therefore and make disciples of all the nations, baptizing them in the name of the Father and the Son and the Holy Spirit."
The reader will notice Jesus' use of the term "name" signifying the unity of God's essence or nature as "One God" (hence "one God in unity"). Then Jesus mentions of course the Three Persons of the Trinity, of which He as the incarnate Son is a member as it pertains to His deity (hence "unity in Trinity").
Closing thoughts for today
As we work our way through each of the above pairs of truths, I'll utilize the Baptist Faith and Message's second article on the doctrine of God which readers can find here Baptist Faith and Message 2000 - The Baptist Faith and Message. As we work through these next four posts, I'll offer applications for the reader so that they can see how practical, as well as worshipful a study of the doctrine of the Trinity can be.
