Alternate title: “Trinitarian Heresy 101”
“The doctrine of the Trinity is like an egg: three parts, one thing.” Ever heard that? How about this, “The doctrine of the Trinity is like a three leaf clover: three leaves, one clover.” Or how about THIS, “The doctrine of the Trinity is like water: three forms (ice, steam, liquid) one substance.” But the greatest I ever heard was by a guy in one of my classes. He said that he thought that the Trinity was like 3-in-1 shampoo: three activities, one substance.”
Stupid statements. Creative, but stupid. Don’t use them. Any of them. Ever.
Explanation coming… Hang with me.
Last week I taught a group of kids about the doctrine of the Trinity here at the Credo House as part of our Theology for Kids series. The ages were anywhere from 7 to 13. Though I regularly teach this subject to adults, this was the first time that I taught the doctrine of the Trinity to kids. I was surprised that it went well. It is confusing enough for adults, how much more for kids?
Teaching the Trinity, I have found, is more about giving basic principles of what it is and then shooting down illustrations about what it is not. Proper Trinitarianism is about a delicate balance between the unity and diversity in the Godhead. Christians believe in one God, i.e., one essence, who eternally exists in three separate persons, all of whom are equal.
We often employ illustrations that help us to make the ineffable, effable, the abstract, concrete. But when it comes to the nature of God, especially with regard to the Doctrine of the Trinity, illustrations should only be used to show what the Trinity is not.
Let me list the three major heresies or departures from orthodoxy with regard to the Trinity:
1. Modalism: The belief that God is one God who shows himself in three different ways, sometimes as the Father, sometimes the Son, and sometimes the Holy Spirit. It describes God in purely functional terms. When he is saving the world on the cross, he is called Jesus. When he is convicting the world of sin, he is called Holy Spirit, and when he is creating the world, he is called Father. The error here is that this is contrary to what we believe: one God who eternally exists in three persons, not modes of functionality. It is not one God with three names, but one God in three persons.
2. Tritheism: The belief that we have three Gods, all who share a similar nature, but not the exact same nature. In this, the nature of God is either distinguished or divided, which destroys the unity of God. We don’t believe in three persons who share in a species called “God,” but three persons who share in an identical, united nature. Continue Reading →
