Origins of the doctrine of the Trinity

Although the doctrine itself wasn’t fully defined until the fourth century A.D., the common, popular belief of the early Church was in the divine nature and essential unity of the Father, Son, and Holy Spirit. But, just like the finalizing of the biblical canon happened out of a response to false teaching (see Chapter 6), so too the doctrine of the Trinity was not fully developed until the spread of false teaching forced the Church to deal with the matter once and for all. 

Sebellius was a Roman teacher who lived in the third century. He said that one God exists, but that he revealed himself in history in three different, temporary ways. His position later came to be known as modalism. Next, in the early fourth century, a teacher named Arius again focused on the unity of God, arguing that Jesus was not God, but instead was the first and greatest of created beings, something like a super-angel. (This Arianism position is very similar to what Jehovah’s Witnesses believe today, which explains why the Christian Church doesn’t consider Jehovah’s Witnesses as part of it.) The beliefs of Arianism spread rapidly, and soon the Church began to divide over this issue. Although Arianism was popular in some Church circles, the local churches rejected it.  

Around this time, Emperor Constantine, who saw Christianity as a way to bring his people together and stop regional in-fighting, took control of the vast Roman empire. But in order to use the religion as a tool, he needed to deal with this split in the Church. As a result, in A.D. 325, Constantine called together a council of Church leaders in the town of Nicaea in order to settle this issue. The council met and reached a consensus that Christ was indeed God, which they wrote down and called the “Nicean Creed,” but Arianism still had a foothold for some time. Another council that helped further define the doctrine was held in A.D. 381 at Constantinople. Since that second council, the Nicean Creed has stood for nearly 17 centuries (see the sidebar, “The Nicean Creed,” later in this chapter) as a basic, non-negotiable belief of the Christian faith. 

A key early defender of the Trinity was Athanasius, who was one of the Church leaders on the Council of Nicaea and devoted his life to upholding the position. Athanasius believed that the Trinity is essential to Christianity and that the Christian understanding of salvation falls apart if Jesus is not God. I explain this idea further in the section “Understanding the Significance of the Trinity.” 

The Trinity made Jesus’ sacrifice worthwhile

The primary reason that the Trinity is essential to Christianity is because of the sacrificial death of Jesus Christ. Christianity says that salvation is possible because Jesus Christ, being fully God and fully man (see Chapter 5 to wrestle with that doozy), was in the unique position of being able to offer the perfect sacrifice on behalf of all people – because he was perfect. 

If Jesus wasn’t God, then his sacrifice would’ve been illegitimate – meaningless. The Old Testament clearly says that humans can’t achieve salvation on their own, picking themselves up to God by their own bootstraps. The Israelites tried that route by following the Law that God, through Moses, gave them. But they failed to keep up their end of the bargain with God, falling into disobedience time and time again. Therefore, if salvation is possible, it must fall on God and God alone to provide it on his own initiative and his own doing, not on anyone else. 

Further, Jesus Christ can’t simply have been some super-angelic lackey that God sent to the earth to do his dirty work for him. Because God is the one grieved by people’s sin, he’s the only one in a position to restore the severed relationship between humans and himself. Or, to put it in a catch phrase: He alone can atone. 

The Trinity justifies worshiping Jesus

A second reason supporting the practical significance of the Trinity deals with worshiping Jesus. Quite simply, if Jesus isn’t God, then it makes no sense to worship him. You wouldn’t worship any other good person, would you? You may respect him, but that’s a whole different ballgame. 

Christians believe that the Ten Commandments make it clear that humans are to worship one and only God, and no one – or nothing – else. Whenever the Bible says angels appeared, it also says that they told people not to worship them, which reinforces this point. 

Yet, Jesus encouraged worship of himself, and the apostles emphasize that throughout the remainder of the New Testament. Because Christians believe that Jesus spoke the ultimate truth (see Chapter 5), they trust his encouragement to worship him and regard him as Lord. And because Jesus is the only human the Bible tells us to worship, that instruction helps back up the claim that Jesus is indeed God, in light of the Bible’s earlier instruction to worship only the one true God. 

Digging Up the Biblical Foundation of the Trinity

It would surely make for a great quiz show question: What is a key component of historical, biblical Christianity, but isn’t once mentioned by name in the Bible? The answer: the Trinity. Although the Bible doesn’t call it out by name, scripture reveals the Trinity doctrine as an underlying theme in several different ways. 

Over the years, some people have objected to the idea of the Trinity because it’s not explicitly found in the Bible. But it’s important to keep in mind that the Trinity creed is intended only to explain what Christians believe the scriptures imply, not expand on them. 

Consider the following parallel which explains how Christians got the idea of the Trinity doctrine. Suppose I come up to you and share with you the following story: 

I drove to the store today. But before leaving my garage, I put the top down, because it was sunny outside. At the store, I had a flat tire and called AAA to come fix it for me.

Although I never once mention a convertible car by name, it’s obvious that it’s the underlying subject of the story. In fact, no other vehicle – a bicycle, semi, or a horse carriage – would provide a logical explanation that takes into account all of the stated details. In much the same way, the Trinity is like the convertible – the lone explanation that is consistent with the characteristics of God that scripture portrays.
