Why It Matters – The Trinity

Why It Matters – The Trinity

Twenty years ago, as a teenage boy, I sat in a school gym and listened to a passionate West Texas preacher expound on various Christian beliefs. I was a Christian, but I was also a teenage boy, so while I was comfortable sitting and listening to his strong raspy voice explain the things of God, my mind also wandered to and fro. Today I can’t recall much of what he said, but I can tell you this: at one point in his sermon, he made an analogy that has stuck with me ever since, and has even been profound in shaping the way I think about the nuanced beliefs of different Christians.  In his deep Texas drawl, he said,

“Boys, Christian beliefs are like two kinds of trees. Oak trees and willow trees. Willow tree beliefs are things like styles of worship, kinds of baptism, or even predestination and free-will. Just like a willow tree, we can flex and bend in the wind, and good, God-fearin’ people can disagree about ‘em. But some beliefs are oak trees. Where they are planted by God, they must stay, never movin’ no matter how hard the wind blows. Oak tree beliefs are ones like the authority of Scripture, the divinity of Christ, salvation by grace alone, and the Holy Trinity.  Them are oak trees – and always will be.”

I’ll never forget that preacher, and I’ll never forget his words.

In this blog series entitled “Why It Matters”, we will be taking a look at some oak trees of Christianity. The goal is not to offer an exhaustive theological explanation of each oak tree tenet. There are many volumes by much more qualified authors that do that already.  Rather, the primary goal is to explore just one reason – among many – why these theological beliefs matter. After all, being able to name our theological beliefs is one thing; being able to think about them and understand why they matter is another.

The Trinity: What it Is

Did you know the word “trinity” is not found in the Bible? How is it then that we believe something that isn’t even mentioned in Scripture?  While the word Trinity is missing in Scripture, the doctrine is not. Contrary to popular belief, the Bible is not solely a book of doctrines about God. The Bible is a story. It’s a narrative that through story-like histories tells us who God is, who we are, and what we are to do about it. In that narrative we find truths, revealed and understood by the power of the Holy Spirit, that become what the Church knows and teaches about God. The Trinity is one of the most important of those beliefs.

To believe in the Trinity is to say that you believe in one God that exists, and has always existed, in three persons: God the Father, God the Son, and God the Holy Spirit. While each is different and has varying roles, they are equal parts of the whole. God the Father does not act independently of the Son. Jesus, the Son, does not act independently of the Spirit, and the Spirit does not act independently of either Father or Son. So, when Adam and Eve encountered God the Father – when the disciples encountered Jesus – and when you have encountered the Holy Spirit – each was an encounter with the Trinity; the Father, the Son, and the Spirit in one.

The Trinitarian nature of God is seen regularly throughout Scripture. Multiple times in the Old Testament, God is plural. He is the epitome of the “royal we.” When creating men and women God says, “Let us make human beings in our image, to be like us.” (Genesis 1:26 NLT, emphasis added) God continues to speak of himself as a plural being in response to the Tower of Babel (“Come, let us go down…” – Gen 11:7) and through the words of his prophet Isaiah (“Then I heard the voice of the Lord saying, ‘Whom shall I send, and who will go for us?’” – Isaiah 6:8).

The three persons of our one God are revealed more clearly in the New Testament. In Mark 1:9-11, Father, Son, and Holy Spirit make an appearance at Jesus’ baptism. In John 1:1-5 we are taught that Jesus is the “word made flesh” and was present with the God the Father and the Spirit as he laid the foundations of the world (Gen 1:1-2). Jesus commands his disciples to make new disciples and baptize them “in the name of the Father, and the Son, and the Holy Spirit.” (Matt 28:19-20) This pattern of unified relationship continues as Jesus promises the Holy Spirit (John 14:15-20) and prays (John 17:20-23), as the apostle Paul gives Trinitarian salutations (2 Corinthians 13:14) and writes of Jesus’ divinity (Colossians 1:15-20), and Jesus’ dear friend John begins the Revelation with a greeting in the name of the Trinity (Revelation 1:4-5).

So the Trinity is God in three persons. But so what? The Trinity may be fundamental to Christian belief, but why does it matter?

The Trinity: Why it Matters

My church is currently on a “Life Group” kick. Your church may call them Cell Groups, or Small Groups, or Home Bible Studies, but whatever the name, the concept is the same. A group of people meeting regularly in someone’s home or at church to study Scripture, talk, and pray together. The goal of these small groups is the same as many of the church’s other programs: to build small communities of people in loving relationships. In fact, that’s one of the goals of local churches: worship, Bible studies, outreach teams, groups for youth, young adults, married people and seniors. Each group is designed to facilitate community and any church should stress the need for community and provide ways to build it.

Being involved in loving and serving relationships isn’t an invention of the Church. It’s at the very core of the identity of the God who created the Church.

That is why believing in the Holy Trinity matters. Our belief that God is one God in three persons is a belief that the God of the Bible exists in perfect, loving relationship. He always has, and he always will. So lovingly investing ourselves in others, and allowing them to invest in us, is not just living as God wants us to live, it’s living as God actually lives! Remember in Genesis 1:26, God tells us that we were made in his image, and in Genesis 2:18, he tells us that it’s not good for us to be alone? Put these two truths together and you get a picture of God reflected in his creation – his people bearing his likeness as they live in loving community. Scripture echoes the design for community throughout (Ecclesiastes 4:12, Proverbs 15:22, 18:22, 27:17, John 17:22-23, Acts 2:42).

You’ve heard the phrase, “do what I say, not what I do”, right? The opposite is true with God. God never asks of us that which he hasn’t already done or is not already doing.  He loved us, and tells us to love others. He forgives us, and asks us to follow suit. He exists in community – the Trinity – so he teaches us to live that way too.

God calls us into community, into relationship, not because he thinks it’s good for us, but because he has personally existed in relationship as the Holy Trinity for all eternity past, so he knows it’s good for us.

Believing in the Trinity is a belief about church, about small groups, about marriage and about family. It’s a belief that to live as God lives is the very best way to live. It’s the belief that our happiness is found by entering into a relationship with God and with others.

Why does the doctrine of the Trinity matter? Because in it we see that living in relationship – even though it is difficult and counter-cultural – is the very best way to live. God does it, so why not you?

Hi y’all! My name is Christopher and I live in Costa Mesa, CA with my amazing wife, Kerry. I’m a writer and a Young Adult Pastor at St. Andrew’s Presbyterian Church in Newport Beach, CA. And this is how good God is: I was born in the greatest state in the Union (Texas!) and I now live, work, and write in one of the most beautiful places on the planet (Southern California!). Life is good. I am excited that you have found Trochia, a place online to be mentored through God’s grace and truth. God has used mentorship relationships to change my life. Keenan, my friend and former boss helped me to see that my work and relationships were about far more than just “getting the job done.” My current mentor, Stan, is a Christian author who has taught me that Christians (no matter what age) can be intellectually engaged with God and culture in a way that is current, fun, and makes disciples. And I’m forever thankful to God for my parents who are my most influential mentors in faith, marriage, family, and life. Without mentorship, I would not be the man I am. That is why mentorship, along with God’s calling for us to “make disciples” and “teach them to obey everything that [He] commanded” (Matthew 28:19-20), is part of everything I do as a writer and as a young adult pastor. I hope that Trochia will be a resource that helps you receive God’s grace and understand His truth, so that you can take one obedient step after another and mentor others along the way. Check out my two latest devotional books: Easter Is Coming and Christmas Is Coming, available through Amazon.com.

    God the Father sent his only Son as “the perfect lamb sacrifice” to die for all of mankind’s sins so that we who have accepted this free gift shall have eternal life. Jesus while here on earth said he and the Father are one. He was trying to get his disciples to realize that he and the Father were one in the same. He said,” if you have seen me, you have seen the Father”. Before Jesus ascended to heaven he said he would send a comforter; the Holy Spirit. Jesus was seen by us.The Holy Spirit is not seen by us, but is a very real presence to those who believe in Jesus Christ, the Son of God.

    well the Trinity has always been, and always will be, and the best ceviche’ used to be at that little cafe, 2nd floor overlooking Newport harbor…..and as well in Native American beliefs, which date back before Christ, they new God, that there would be a son, and tremendously respected the Holy Spirit, as there were 4, one for each direction….Thomas Mails, an Episcopalian Priest, noted author of the Native Nation of America….who actually lived with the Legendary , Chief Fools Crow, to write his autobio, an amazing read, Chief Fools Crow, noted as the most Spiritual Leader of the Native Nation at that time by Mails

    The word “Trinity” – like “incarnation” – is not found in Scripture; however, it aptly codifies what God has condescended to reveal to us about His nature & being. Scripture clearly portrays subject/object relationships between Father, Son, & Holy Spirit.

    Trinity is the belief that Christ did not actually die on the Cross, that He did not actually cease to live for the three days that He was dead in the tomb. Trinity makes the faith of Jesus unto death a mockery and nothing more than an Oscar-worthy performance.

    This always makes my head spin. Jesus has always existed and waited thousands of years before coming to earth to be sacrificed. I can’t even begin to imagine a super-Being like that, but I’m grateful that I know Him.

  • Alvin Peebles

    My understanding is because the first Adam failed in their responsibility given to them by God, all of mankind born after the fall was cursed to die with them ,but God already had plan of redemption settled in heaven ,He had a sacrifice already accomplished , for our sin ,and it had to be sinless for true justice ,and the next Adam ,a new beginning for mankind , All who come after Him ,with Him ,have Endless Life , so the phrase born again…..

    The way God speaks this is the most captivating truth you will ever hear – Isaiah 48: 16-17 says … “Come near to me and listen to this … From the time that it was (the beginning) – there I AM . And now the Lord God (one) – and His Spirit (two) – hath sent Me (three). THUS (thus means in the way just spoken … 3 in one – ) THUS saith the Lord, thy Redeemer, the Holy One of Israel , I AM THE LORD THY GOD . . . which teacheth thee . . . which leadeth thee by the Way that thou shouldest go “. . . AND WHEN PEOPLE WONDER “Why do those Christians think of Jesus as God?” – – – The being that was sent into the world was and is JESUS CHRIST of NAZARETH . The incredible beauty also is . . . keep reading from Isaiah 48: 16-17 thru Isaiah 49 – 50 – 51 – ( Isaiah 52: 14-15 is what the Passion of The Christ Movie was made from) – and ISAIAH 53 all REVEALS the Life Of Jesus who was SENT INTO THE WORLD – . . . ” hath sent me ” …

    Such verses do show that the New Testament Faith is a Trinitarian faith. While God is one being, he exists eternally as three coequal and coeternal Persons, whom we know as the Father, the Son and the Holy Spirit. there are three whos within the one being of God, that is, the three divine Persons—Father, Son and Holy Spirit. Because that specific word isn’t in the Bible does not prove there is no Trinity.. There are many words that’s not in the Bible, such as the word Bible….. NEXT…

    No.  Yahowah is ONE; Yahowsha is a ‘part of Yahowah’ set apart from Him to serve us; the Spirit is also just a part of Yahowah, She is set apart from Yahowah to serve us.  They are all part of One Yahowah.

  • LassieMettler
    July 9, 2013 at 4:51 pm

    I Am Yahowah; there is no saviour besides Me.  Yahowsha is a very small part of Yahowah who is qodesh, qodesh, set-apart twice– a diminished manifestation of Yahowah; He is the part of Yahowah that we can ‘see’.  Yahowsha is not co-equal with Yahowah, He is only a ‘part’.

    I don’t think I really “Think” – about them … for they are as real as breathing out, and breathing in. When I wake up in the morning, the first sound I feel in my mouth is “Thank you Jesus” – and it feels so right to say it . I think of Him off and on all day – and talk to him off and on all day. The last sound I feel in my mouth at night is “Thank You Jesus” – I will never be able to thank Him enough for what he has done for me and my loved ones. And one more thing I am waiting for Him to do – I don’t know how He will do it – – – but I know HE knows how – and that is all that matters to me. And I can’t wait to see His Beautiful face.
