Before we can understand the Incarnation and how God did not change in the Incarnation, we must first understand the Trinity. This is certainly no easy task for quite a few reasons. First, I am writing in a limited space, so even if we could comprehend God, I would not accomplish this in so few pages.
Secondly, we cannot comprehend God, so I cannot really explain the Trinity. What I can explain is what has been revealed, but I cannot explain the Trinity and how the three persons function. Rationalists need not apply in attempting to understand the Trinity or looking at the Trinity; the Trinity is a mystery and therefore cannot be comprehended.
The third reason this is not an easy task is that while what we can know of the Trinity is substantial, space and time are limited. St. Hilary of Poitiers spent the modern equivalent of 300 pages writing about the Trinity. St. Augustine spent the equivalent of nearly 500 pages writing about the Trinity. Yet both men felt that their works were inadequate. I am using only a fraction of space to write about the Trinity as these two great thinkers did, so I am positive that my explanation will be inadequate.
Regardless of the inadequacies, I will attempt to explain the Trinity to the best of my knowledge. It is my hope that in understanding the Trinity we can gain a better understanding of the Incarnation and in so doing we can understand how Christian theology does not contradict the Damascene Cosmological argument.
