I have long thought that arguing over Trinitarian nuances is often a waste of breath. I understand bad things can be said about the Trinity, to the point of blasphemy, but it’s also pretty impossible to explain it correctly, so relax a little bit.
I know an egg with the yoke, white, and shell is not an adequate description of the Trinity, it’s called Modalism and was considered heresy by the Early Church. No problem, I get it, it’s not adequate to the task. At the same time, it’s not a bad way to get the idea across to a kid. But yeah, it lacks strict accuracy.
The problem is that the Bible doesn’t articulate it, so there’s no succinct way to explain it. It’s an extrapolation from many verses.
One of the approved views of the Trinity is in the Athanasian Creed. When someone gives a theological, big worded explanation of the Trinity, it’s usually borrowing from the Athanasian Creed.
For instance, Legonier ministries, RC Sproul’s outfit, has a quote in an article about the Trinity saying this:
“The content of the Athanasian Creed stresses the affirmation of the Trinity in which all members of the Godhead are considered uncreated and co-eternal and of the same substance.”
You will also find this in the Westminster Shorter Catechism:
“There are three persons in the Godhead; the Father, the Son, and the Holy Ghost; and these three are one God, the same in substance, equal in power and glory”
So you’ll hear this word “substance” in official sounding definitions of the Trinity.
You should know that many people have found fault with the word “substance.”
As far as I can tell, “substance” is a word that Augustine used in relation to the persons of Jesus Christ and God the Father. He said that the Son was of the “same substance” as the Father.
Arianism, a classic Early Church heresy, said that Jesus was not divine but was rather a created being. Saying Christ was of “the same substance” as the Father is the way they defended the person of Christ from Arius and his boys.
But guys like Isaac Newton and others found fault with the use of the word “substance.” God is a spirit, how is there a “substance?” Substance is sort of a philosophical word. Newton said it wasn’t a biblical word; therefore, we shouldn’t use it to define the person of God.
I like that! I am a firm believer that as much as possible we should say things the way the Bible does with the Bible’s terms. Unbiblical words to describe biblical things always make me nervous.
Because Newton challenged the idea of “substance” in definitions of the Trinity, you will often see Newton described as an Arian heretic. Don’t be so quick! Just like anyone who questions Calvinism is immediately called a Pelagian, when in reality they are just questioning Calvinism. The opposite of Calvinism is not heresy and the opposite of using “substance” in the Trinity is not heresy.
Be careful of that trap: anyone who doesn’t agree with me is a heretic.
Here’s a quote from an article about Newton’s views of the Trinity on this issue:
He . . . embraced the straightforwardly biblical position that the Father and Son are one. What Newton did not believe, however, was that the Father and Son were one in the sense that they were consubstantial or of the same substance. According to Newton, the Father and Son were one, but this unity was not a metaphysical unity; rather, it was one of dominion and purpose.
I applaud his efforts to want to be biblical! Please, more of this!
“Substance” is a word related to Greek philosophy. Augustine was steeped in Greek philosophy. When he uses words that are not biblical, you must assume he is using a Greek philosophical term. Thus, I have no idea what “substance” means to him, and whoever hears you use the term also has no idea what you mean.
What “substance” does do is make you think of a physical object, a thing with, well, substance. This seems misleading.
I prefer to stick with the Bible, like Newton, and just say that the Lord is one, and Jesus and the Father are one. Simple. Leave it there. When theologians start using many words they complicate the issue and often to the point of not helping.
Keep it simple. Keep it biblical. The end.
