Why can't it be that simple? Are you saying that where scripture makes clear Father-Son-Holy Spirit that...it doesn't really mean that, or it's really more or less? Ok. This should be interesting, have at it, I'll listen.
I read earlier where another poster took a jab at Greek philosophy. I would argue Greek philosophy is integral to understanding Christianity. It is not a mere coincidence that the Hebrew world converged with the Hellenistic world at the Incarnation. The New Testament Scriptures themselves were written in Greek. Philosophy is ultimately the understanding of distinctions and is therefore necessary to study theology. The New Testament is full of Greek philosophy, used to convey the truths of the Christian faith. This is most beautifully captured by St. John and his description of the Son of God as
Logos. Furthermore, St. Paul can rightfully be called the first Christian philosopher as he repeatedly uses Greek philosophy to make theological distinctions about the Person of Christ. He uses the thoughts and words of Aristotle, Seneca, Aratus, Plato, Menander and Socrates to describe and explain the mysteries of the Christian faith. When recounting his own conversion experience, he even has Jesus quoting the Greek poet Euripides' play,
Bacchae!
(cf. Acts 26:14)
That said, I will attempt to use distinctions to help understand why when describing the Trinity, it is not as simple as saying, "Father, Son and Holy Spirit."
God is a Trinity, but what does that mean? Here is where distinctions come in: It means that God is
three Persons in
one Nature. It can be summarized in four statements:
1. In the One Divine Nature, there are Three Persons – the Father, the Son (also called the Word, or Logos) and the Holy Spirit.
2. The Father is not the Son, the Son is not the Holy Spirit, the Holy Spirit is not the Father. In other words, no one of the Persons is either of the others.
3. The Father is God, the Son is God and the Holy Spirit is God.
4. There are not three Gods, but one God.
Three Persons, but one Nature. What does that mean? Nature answers the question of what we are and person answers the question of who we are. Every being therefore has a nature. Nature explains what we do, as every being acts according to what it is. If you look at us, for example, there are numerous things our nature allows us to do: we can move, walk, run, think and most importantly, love. We can do these things because we have a human nature which makes them possible. A rock, however, could not do those things, as its nature does not allow it. While nature decides what actions or operations are possible for us to do, it is not our nature that actually does them, but rather our person who does. The person is the one who does the action and the nature is that by virtue of which the actions are done.
When we are describing God, we say He is Three Persons but One Nature. God is three distinct Persons and no one of them is either of the others and each is what He is by the total possession of the one same nature. They do not share the Divine nature, but rather possess it entirely. The Father possesses the whole nature of God as His own, the Son possesses the whole nature of God as His own, the Holy Spirit possesses the whole nature of God as His own. Each person is God, wholly and therefore equally with the others. And since nature decides what the person can do, each of the three persons who possess the Divine Nature can do all the things that go with being God. The Three Persons are God, not by the possession of equal and similar natures, but by the possession of one single nature.
Hence, to say that God is "Father, Son and Holy Spirit" requires
qualification and distinction. For even those who oppose the Trinity can say "Father, Son and Holy Spirit" because they believe God is not Three
Persons. For example, Modalism, Docetism and Arianism (even in its modern day version called the Jehovah's Witnesses) all say "Father, Son and Holy Spirit" but reject the Trinity.
I hope this helps.
God bless.
