How is the Trinity Explained?
The main theme of this section is that the Trinity is difficult to understand, even contrary to human reason, and a number of quotes, mostly from Catholic sources, are quoted to illustrate that the Trinity is an incomprehensi­ble mystery. To begin with, let us admit that there is a difference between what is illogical or unreasonable and what is beyond our understanding. For example, physicists tell us that certain building blocks of reality (quanta) are both waves and particles. How can they be both? The physicists themselves don't fully understand, but assume that one day we will have sufficient data to explain why a quantum can have the properties of both a wave and a particle. In other words, there is a solution to the problem that further research may supply. What I want to suggest to you is that the doctrine of the Trinity is like this. It is the only explanation that makes sense of what the Bible actually says about God, but God does not give us enough data to fit it all together. This does not mean that it is unreasonable, any more than electrical theory is unreasonable because an Australian aborigine doesn't understand or believe in electric light bulbs.
In fact, the Bible teaches that God himself is beyond our understanding. Both the Jehovah's Witness and the Christian admit that God is infinite. Therefore we can never comprehend him in his totality, because we are finite. God is unlimited and we are limited. Consider Ps 145:3, and Isa 55:8-9:
Great is the Lord, and most worthy of praise; his greatness no one can fathom (NIV). "For as the thoughts of you people are not my thoughts, nor are my ways your ways", is the utterance of Jehovah, "For as the heavens are higher than the earth, so my ways are higher than your ways and my thoughts than your thoughts" (NWT).
