What is the Christian doctrine of the Trinity?

The Christian doctrine of the Trinity

I have a friend who is considering Christianity and he is stuck on the doctrine of the Trinity. Tom, this one’s for you.

Excerpt:

So, what exactly do we mean when we talk about the Trinity? Writing in the early third century, in hisAgainst Praxeas, Tertullian is credited with first employing the words “Trinity”, “person” and “substance” to convey the idea of the Father, Son and Spirit being “one in essence — but not one in person”. Indeed, Tertullian writes,

“Thus the connection of the Father in the Son, and of the Son in the Paraclete, produces three coherent Persons, who are yet distinct One from Another. These Three are, one essence, not one Person, as it is said, “I and my Father are One,” in respect of unity of substance not singularity of number.”

This concept was established as church orthodoxy at the famous Council of Nicaea in A.D. 325. The Nicene Creed speaks of Christ as “God of God, Light of Light, very God of very God, begotten not made, being of one substance with the Father.”

It is this definition that I am going to assume in the discussion that follows. Succinctly, then, the doctrine of the Trinity may be defined thusly: Within the one being or essence that is God, there exists three co-equal and co-divine distinct persons — namely the Father, Son and Holy Spirit — who share that essence fully and completely. This concept is not to be confused with polytheism, which maintains that there are multiple gods. While orthodox Christianity emphatically holds there to be only one God, we nonetheless understand God to be complex in his unity. The concept is also not to be confused with the ancient heresy of modalism, which maintains that God exists in three different modes. The Son has never been the Father and the Holy Spirit has never been the Son or the Father. Modalism is refuted by the picture given to us in all four gospels (Matthew 3:16-17; Mark 1:9-11; Luke 3:21-22; John 1:32-34) in which the Holy Spirit descends on Jesus in the form of a dove and a voice is heard from Heaven “This is my beloved Son. With him I am well pleased.” Similarly, it should be noted that the Father, Son and Spirit do not each make up merely a third of the Godhead. Rather, each of the three persons is God in the full and complete sense of the word.

Having shown that Scripture emphatically rejects the notion that the Father, Son and Spirit are synonymous persons, only five propositions remain to be demonstrated in order to provide Biblical substantiation for the concept of the Trinity. Those propositions are:

  1. There is only one eternal God.
  2. The Father is the eternal God.
  3. The Son is the eternal God.
  4. The Holy Spirit is the eternal God.
  5. Although the Father, Son and Holy Spirit are non-synonymous persons, the concept of the Trinity does not violate the law of non-contradiction.

Let’s take a look at each of these in turn.

He then takes a close look at what the Bible says about God with respect to those assertions. There can be no doubt that the Bible teaches that God is one divine substance, and three persons.

J.W. Wartick: a philosophical challenge to Mormonism

It’s here on his blog “Always Have a Reason”. He critiques two concepts of God in Mormonism: Monarchotheism and Polytheism. I think most of you will already know about the infinite regress critique of Mormon polytheism, so let’s take a look at this Monarchotheism.

Excerpt:

Stephen Parrish and Carl Mosser take Mormon teaching to expound the concept of God known as Monarchotheism, “the theory that there is more than one God, but one God is clearly preeminent among the gods; in effect, he is the monarch or ruler of all the gods” (Parrish and Mosser, 195, cited below). This concept of God is embodied (see Teachings of the Prophet Joseph Smith cited in P+M, 201). Furthermore, this God is contingent, the organizer of a world that was originally chaos, and one of many gods (Ibid, 201). Furthermore, Joseph Smith himself taught that this “God himself was once as we are now, and is an exalted man…” (TPJS 345, cited in P+M, 202).

[…]There are many difficulties with this Mormon concept of God. Perhaps most crucial is the inclusion of contingency in the concept of God. If God is contingent, then it does indeed beg the question “Who Made God?” Consider this against classical theism, which holds that God exists necessarily. Classical theists can respond to this question by simply saying, “No one made God, because God, as necessarily existent, never came into being.” Yet Mormons who hold God is contingent must answer this question.

That’s not the only difficulty with God as contingent either, for holding that God is contingent removes several of the reasons to believe that such a deity exists. Consider one of the classical arguments for the existence of God: that contingent things have all come into being, so there must be something which has always existed in order to terminate the infinite regress. Of course, if this deity which terminates the regress is, itself, contingent, then one must continue the regress to the next step. Thus, this Mormon concept of God provides no grounding for the universe itself.

He has a couple more critiques to this position as well. But relevant to the contingency problem is the evidence from modern physics. If the Mormon God does not exist eternally, then it could not be the cause of the universe. Therefore, the universe could not have come into being on Mormon theology. Mormon theology requires an eternal universe, putting it at odds with Christian theology, as well as the Big Bang cosmology.

You can read my article on Mormonism right here. I attack Mormonism on scientific and historical grounds. First, the conflict with modern cosmology. Second, the Book of Abraham is a fraud – it’s an Egyptian burial narrative.

Does the Bible teach that faith is opposed to logic and evidence?

Probably the biggest misconception that I encounter when defending the faith is the mistaken notion of what faith is. Today we are going to get to the bottom of what the Bible says faith is, once and for all. This post will be useful to Christians and atheists, alike.

What is faith according to the Bible?

I am going to reference this article from apologist Greg Koukl of Stand to Reason in my explanation.

Koukl cites three Biblical examples to support the idea that faith is not blind leap-of-faith wishing, but is based on evidence.

  1. Moses went out into the wilderness and he had that first encounter with the burning bush, and God gave him the directive to go back to Egypt and let his people go. Moses said, Yeah, right. What’s going to happen when they say, why should we believe you, Moses?God said, See that staff? Throw it down.Moses threw it down and it turned into a serpent.God said, See that serpent? Pick it up.And he picked it up and it turned back into a staff.God said, Now you take that and do that before the Jewish people and you do that before Pharaoh. And you do this number with the hail, and the frogs, and turning the Nile River into blood. You put the sun out. You do a bunch of other tricks to get their attention.And then comes this phrase: “So that they might know that there is a God in Israel.”
  2. [I]n Mark 2 you see Jesus preaching in a house, and you know the story where they take the roof off and let the paralytic down through the roof. Jesus said, “Your sins are forgiven.” And people get bugged because how can anyone forgive sins but God alone?Jesus understood what they were thinking and He said this: What’s harder to say, your sins are forgiven, or to rise, take up your pallet and go home?Now, I’ll tell you what would be harder for me to say : Arise, take up your pallet and go home. I can walk into any Bible study and say your sins are forgiven and nobody is going to know if I know what I am talking about or not. But if I lay hands on somebody in a wheelchair and I say, Take up your wheelchair and go home, and they sit there, I look pretty dumb because everyone knows nothing happened.But Jesus adds this. He says, “In order that you may know that the Son of Man has the power and authority to forgive sins, I say to you, arise, take up your pallet and go home.” And he got up and he got out. Notice the phrase “In order that you may know”.  Same message, right?
  3. Move over to the Book of Acts. First sermon after Pentecost. Peter was up in front of this massive crowd. He was talking about the resurrection to which he was an eyewitness. He talked about fulfilled prophecy. He talked about the miraculous tongues and the miraculous manifestation of being able to speak in a language you don’t know. Do you think this is physical evidence to those people? I think so. Pretty powerful.Peter tells them, These men are not drunk as it seems, but rather this is a fulfillment of prophecy. David spoke of this. Jesus got out of the grave, and we saw him, and we proclaim this to you.Do you know how he ends his sermon? It’s really great. Acts 2:36. I’ve been a Christian 20 years and I didn’t see this until about a year ago. This is for all of those who think that if you can know it for sure, you can’t exercise faith in it. Here is what Peter said. Acts 2:36, “Therefore let all the house of Israel know for certain that God has made him both Lord and Christ, Messiah, this Jesus whom you crucified.” There it is again. “Know for certain.”

What is faith according to Bible-based theologians?

I am going to reference this article from theologian C. Michael Patton of Parchment and Pen in my explanation.

Patton explains that according to Reformation (conservative, Bible-based) theologians, faith has 3 parts:

  1. notitia – This is the basic informational foundation of our faith. It is best expressed by the word content. Faith, according to the Reformers must have content. You cannot have faith in nothing. There must be some referential propositional truth to which the faith points. The proposition “Christ rose from the grave,” for example, is a necessary information base that Christians must have.
  2. assensus – This is the assent or confidence that we have that the notitia is correct… This involves evidence which leads to the conviction of the truthfulness of the proposition… This involves intellectual assent and persuasion based upon critical thought… assensus… says, “I am persuaded to believe that Christ rose from the grave.”
  3. fiducia – This is the “resting” in the information based upon a conviction of its truthfulness. Fiducia is best expressed by the English word “trust.”… Fiducia is the personal subjective act of the will to take the final step. It is important to note that while fiducia goes beyond or transcends the intellect, it is built upon its foundation.

So, Biblical faith is really trust. Trust(3) can only occur after intellectual assent(2), based on evidence and thought. Intellectual assent(2) can only occur after the propositional information(1) is known.

The church today accepts 1 and 3, but denies 2. I call this “fideism” or “blind faith”. Ironically, activist atheists, (the New Atheists), also believe that faith is blind. The postmodern “emergent church” denies 1 and 2. A person could accept 1 and 2 but deny 3 by not re-prioritizing their life based on what they know to be true.

How do beliefs form, according to Christian philosophers?

I am going to reference a portion of chapter 3 of J.P. Moreland’s “Love Your God With All Your Mind” (i.e. – LYGWYM).

J.P. Moreland explains how beliefs form and how you can change them.

  1. Today, people are inclined to think that the sincerity and fervency of one’s beliefs are more important than the content… Nothing could be further from the truth… As far as reality is concerned, what matters is not whether I like a belief or how sincere I am in believing it but whether or not the belief is true. I am responsible for what I believe and, I might add, for what I refuse to believe because the content of what I do or do not believe makes a tremendous difference to what I become and how I act.
  2. A belief’s strength is the degree to which you are convinced the belief is true. As you gain ,evidence and support for a belief, its strength grows for you… The more certain you are of a belief… the more you rely on it as a basis for action.

But the most important point of the article is that your beliefs are not under the control of your will.

…Scripture holds us responsible for our beliefs since it commands us to embrace certain beliefs and warns us of the consequences of accepting other beliefs. On the other hand, experience teaches us that we cannot choose or change our beliefs by direct effort.

For example, if someone offered you $10,000 to believe right now that a pink elephant was sitting next to you, you could not really choose to believe this… If I want to change my beliefs about something, I can embark on a course of study in which I choose to think regularly about certain things, read certain pieces of evidence and argument, and try to find problems with evidence raised against the belief in question.

…by choosing to undertake a course of study… I can put myself in a position to undergo a change in… my beliefs… And… my character and behavior… will be transformed by these belief changes.

The article goes on to make some very informative comments on the relationship between apologetics and belief.
