The word “trinity” is a term used to denote the Christian doctrine that God exists as a unity of three distinct persons: Father, Son, and Holy Spirit. Each of the persons is distinct from the other, yet identical in essence. In other words, each is fully divine in nature, but each is not the totality of the Trinity. Each has a will, loves, and says “I”, and “You” when speaking. The Father is not the same person as the Son who is not the same person as the Holy Spirit who is not the same person as the Father. Each is divine, yet there are not three gods, but one God. There are three individual subsistences, or persons. The word “subsistence” means something that has a real existence. The word “person” denotes individuality and self awareness. The Trinity is three of these, though the latter term has become the dominant one used to describe the individual aspects of God known as the Father, the Son, and the Holy Spirit.
Included in the doctrine of the Trinity is a strict monotheism which is the teaching that there exists in all the universe a single being known as God who is self-existent and unchangeable (Isaiah 43:10; 44:6,8). Therefore, it is important to note that the doctrine of the trinity is not polytheistic as some of its critics proclaim. Trinitarianism is monotheistic by definition and those who claim it is polytheistic demonstrate a lack of understanding of what it really is.
Is this confusing?
Another important point about the Trinity is that it can be a difficult concept to grasp. But this does not necessitate an argument against its validity. On the contrary, the fact that it is difficult is an argument for its truth. The Bible is the self revelation of an infinite God. Therefore, we are bound to encounter concepts which are difficult to understand — especially when dealing with an incomprehensible God who exists in all places at all times. So, when we view descriptions and attributes of God manifested in the Father, the Son, and the Holy Spirit, we discover that a completely comprehensible and understandable explanation of God’s essence and nature is not possible. What we have done is derive from the Scripture the truths that we can grasp and combine them into the doctrine we call The Trinity. The Trinity is, to a large extent, a mystery. After all, we are dealing with God Himself.
