Summary of Biblical Monotheism and the Trinity
Christian monotheistic belief is summarized by the following seven points:
1. The Father is God.
2. The Son is God.
3. The Holy Spirit is God.
4. The Father is not the Son.
5. The Son is not the Holy Spirit.
6. The Holy Spirit is not the Father.
7. There is only one God.
When Christians say: (1) The Father is God; (2) The Son is God; and (3) The Holy Spirit is God we are identifying Who God is.
When we say: (4) The Father is not the Son; (5) The Son is not the Holy Spirit; and (6) The Holy Spirit is not the Father we are distinguishing the Father, Son, and Holy Spirit.
The seventh and the final statement is the most challenging, “There is only one God”. The Greeks would say, “Zeus is god, “Apollos is god, and Dionysius is god” and there are three gods. Christianity says, the Father is God, the Son is God, and the Holy Spirit is God and there is only one God.

The Christian Doctrine of the Trinity, and Belief in One God Involves Mystery
Now, the question boils down to this: Is this what the Bible teaches? Since the Bible teaches this but we can’t fully comprehend it – that is OK. We must leave room for mystery in our theology.
In church history Saint Augustine (354-430) probably thought more about the doctrine of the Trinity than any other uninspired writer, with the possible exception of John Calvin. There is a story about Augustine walking upon the ocean’s shore, greatly perplexed about the doctrine of the Trinity. As he meditated, he observed a little boy with a sea shell, running to the water, filling his shell, and then pouring it into a hole which he had made in the sand.
“What are you doing, my little man?” asked Augustine.
“Oh,” replied the boy, “I am trying to put the ocean in this hole.”
Augustine had learned his lesson, and as he passed on, exclaimed, “That is what I am trying to do; I see it now. Standing on the shores of time I am trying to get into this little finite mind things which are infinite.”
It should come as no surprise that the Christian belief in the Triune God involves mysteries that transcend the human mind.
Read: 1 Corinthians 2:6-16
No one knows the things of God except the Spirit of God. —1 Corinthians 2:11
When we quote The Apostles’ Creed, we say, “I believe in the Holy Spirit.” Author J. B. Phillips said, “Every time we say [this] we mean that we believe that [the Spirit] is a living God able and willing to enter human personality and change it.”
Sometimes we forget that the Holy Spirit is not an impersonal force. The Bible describes Him as God. He possesses the attributes of God: He is present everywhere (Ps. 139:7-8), He knows all things (1 Cor. 2:10-11), and He has infinite power (Luke 1:35). He also does things that only God can do: create (Gen. 1:2) and give life (Rom. 8:2). He is equal in every way with the other Persons of the Trinity—the Father and the Son.
The Holy Spirit is a Person who engages in personal ways with us. He grieves when we sin (Eph. 4:30). He teaches us (1 Cor. 2:13), prays for us (Rom. 8:26), guides us (John 16:13), gives us spiritual gifts (1 Cor. 12:11), and assures us of salvation (Rom. 8:16).
The Holy Spirit indwells us if we have received forgiveness of sin through Jesus. He desires to transform us so that we become more and more like Jesus. Let’s cooperate with the Spirit by reading God’s Word and relying on His power to obey what we learn.
