“I have much more to say to you, more than you can now bear. But when he, the Spirit of truth, comes, he will guide you into all the truth. He will not speak on his own; he will speak only what he hears, and he will tell you what is yet to come. He will glorify me because it is from me that he will receive what he will make known to you. All that belongs to the Father is mine. That is why I said the Spirit will receive from me what he will make known to you.” – John 16:12-15 NIV
Frankly, I’m not sure I have ever preached a sermon on the Trinity as a theological concept. And, there are several reasons for that.
First, the word “Trinity” is not found in the Bible. That is actually not that unusual because there are a number of theological concepts not found explicitly in the Bible that scholars and Church history and tradition have validated over the past 2,000 years. But the absence of direct teaching from the Bible on the Trinity makes it hard to find a passage of Scripture from which to launch out for a sermon. The passage we read today has hints of a trinitarian relationship between God the Father, God the Son, and God the Spirit, but you have to look carefully for it.
The second reason I haven’t preached directly on the Trinity is because it is a topic, a concept, from the academic discipline called “systematic theology.” Systematic theology, briefly, is the attempt by Christian theologians to craft a coherent understanding of the work of God. Typically systematic theologies are crafted from Scripture, Church tradition, and the overarching philosophy of the particular theologian who is writing. So, the topics of systematic theology tend to be conceptual, and often difficult to explain in a way that doesn’t put a congregation to sleep quickly.
But, the primary reason I think I haven’t preached specifically on the Trinity is because it is one of those doctrines that Christians worldwide affirm, but have great difficulty explaining. The idea of One God in Three Persons — three-in-One — is a concept we have difficulty getting our heads around.
While in seminary in Fort Worth, Texas, I served as associate pastor at a church in Irving. Next door to the church was a large apartment complex that for some reason tended to attract large numbers of international residents. The Dallas-Fort Worth area is home to several major universities such as SMU, TCU, and others, and perhaps that was the draw.
A couple of times young men from the Middle East, mostly Iranians, would come to the church office and ask to speak with a “holy man.” Apparently I was the closest thing we had to one, so I often got to talk with these young Muslim men. The primary thing they wanted to debate with me was the fact that Christianity had three gods. I would then try to explain the Trinity to them, but they, like me, had great difficulty in comprehending how One God could be constructed of Three Persons. I never convinced any of those young men that Christians worshipped One God, but that experience did remind me of how difficult the concept of the Trinity is to explain.
The Trinity in The Shack
Several years ago, an interesting book titled The Shack became a bestseller. The story was compelling, but one aspect of that book sparked discussion and disagreement among Christians. William Paul Young represented the Trinity in a very unique way.
For God the Father, Young portrayed God as a large black woman, who was outgoing, warm-hearted, and kind. For God the Holy Spirit, Young’s persona was that of an Asian woman dressed in bright colors who seemed to dart in and out of sight in a Tinkerbell-like fashion. For Jesus, the author pretty much stayed with the stereotype of Jesus as a workman, complete with jeans, flannel shirt, and toolbelt. Each of these personas of God exhibited unique characteristics, and each had a specific role to play in the fictional story.
But, as creative as that portrayal was, Young’s attempt to give the Trinity personality fell short of capturing the theology fully.
