Today, we seek to understand what we believe. We believe the Son is co-equal with the Father, because he has the divine nature. We believe the Son is co-eternal with the Father, ever from the Father. But how to understand something so lofty?
We have patristic images or metaphors for this. These are beautiful and more easily accessible. We also have a great achievement of dogmatic or speculative theology. This is so beautiful, though difficult. Let us begin the journey of the mind to God by following Augustine and Aquinas on this great labor. Bonaventure and scores of other great saints also took this journey.
