For ages the doctrine of the Trinity has been upheld even though it’s been twisted around a thousand ways to Tuesday. Some people find the doctrine of the Trinity a hard pill to swallow, others think Christians believe in three gods, and still others believe we’re contradicting ourselves all over the place when we discuss these things. Yet, the doctrine of the Trinity is of such importance that if you deny it, you cannot in any real way call yourself a Christian.
Here’s what I want to do this week: Monday I gave you some definitions, and showed you where we get these definitions in Scripture. Wednesday, I showed you common ways people distort this doctrine, and today I’ll show you why this matters.
4) Why Trinity Matters
a) No illustrations: because people throughout history have sought to explain the mysteries of the Trinity with images (like water, man with different roles, three-leaf clover) and failed to do justice to the Biblical doctrine – it is better for us to simply stick with the classic definition: God eternally exists as one in essence and three in Person: the Father, the Son, and the Holy Spirit. They are the same in substance, equal in power and glory.
Anything beyond this, is heresy.
b) God as a relatable being: because God has eternally existed in Trinity, He has always been a being in relationship to others, and within the Trinity there has always been a perfect relational harmony, thus, God stands out as a perfect society within Himself. Acts 17:25 uses this fact to state that God needs nothing, He is independent, because in Himself He is full. Therefore, when God made the world He didn’t do it out of some sense of lack or need. He needed nothing, yet made everything. Why? Jonathan Edwards once said, ‘God as a Fountain, cannot help but overflow.’
c) Trinity as ultimate relational model: the Bible mentions there is a unity within the Trinity, the word Trinity even means this (defined as Tri-unity). Because of this Scripture teaches us how to relate to one another as the Trinity relates to one another. Where do we see how to have unity in diversity? The opportunity to witness the clarity, complexity, duality, creativity, intensity, joviality, and veracity of unity existing alongside diversity is not found in a university nor found in human depravity; it is only found in the community of divinity we call the Holy Trinity.
d) Redemption is possible because of the Trinity: we see this in two ways: First, Exodus 33:20 and 1 Tim. 6:16 teach us that no man can see God and live but God the Son made the invisible God visible. Second, redemption itself is accomplished by the unified activity of the Holy Trinity. We saw this in Ephesians 1, see it again in Hebrews 9:14, ‘…how much more will the blood of Christ, who through the eternal Spirit offered Himself without blemish to God, purify our conscience from dead works to serve the living God?’ All three accomplish salvation.
e) Sing! Because the Church throughout the ages has held the doctrine of the Trinity so close to the heart, many hymns and songs have been written about the Trinity. 3 of them hold a special place in my heart: two traditional songs are the Doxology and the Gloria Patri, and a new one called the Messenger Doxology by Matt Boswell.
