The Trinity is not an introductory doctrine, meant to be set aside after our intellectual assent, to move on to more “practical” subjects. The Trinity is a mystery that defines our relationship with God. We are not talking about the kind of mystery found in a Sherlock Holmes novel, in which we search for clues and deduce a conclusion that is perfectly reasoned and accounts for all the evidence. The mysteries of God are secrets which, in part, have been or are being, disclosed to His people.
Deuteronomy 29:29 “The secret things belong to the LORD our God, but the things that are revealed belong to us and to our children forever, that we may do all the words of this law.
Matthew 11:25-27 At that time Jesus declared, “I thank you, Father, Lord of heaven and earth, that you have hidden these things from the wise and understanding and revealed them to little children; yes, Father, for such was your gracious will. All things have been handed over to me by my Father, and no one knows the Son except the Father, and no one knows the Father except the Son and anyone to whom the Son chooses to reveal him.
This passage is at the heart of the Christian Faith. It is God who reveals himself, in nature to everyman, and in special revelation to those who believe through His Spirit. Indeed, what is revealed belongs to us and to our children forever. Yet, we have to understand that even what is revealed about the Trinity is itself a mystery. There is a progressive revelation in regards to the doctrine of the Trinity. Some aspects of it remain beyond our comprehension. The Trinity, in many ways, will always be a mystery because the finite cannot comprehend the depth and breadth of the infinite. But what is revealed about the Trinity teaches us about our world. A tension between the one and the many permeates our existence; individuals and the collective. This tension is at the heart of our marriages, churches, communities and politics. Self or selflessness? It’s fundamental to being human. And the answer to this tension is Jesus Christ, who reveals the Trinity to us. Who in himself has two natures, divine and human, and what we learn is that harmony between the individual and the collective is found in divine Love.
