The Trinity is a mystery in two senses. It is a mystery in the biblical sense in that it is a truth that was hidden until revealed. But it is also a mystery in that, in its essence, it is suprarational, ultimately beyond human comprehension. It is only partly intelligible to man, because God has revealed it in Scripture and in Jesus Christ. But it has no analogy in human experience, and its core elements (three coequal persons, each possessing the complete, simple divine essence, and each eternally relating to the other two without ontological subordination) transcend man’ s reason.
