To present this in a form which the intellect may apprehend, we borrow an illustration from the Memory, the Understanding, and the Will. For although we can speak of each of these faculties severally in its own order, and at a separate time, we neither exercise nor even mention any one of them without the other two. It must not, however, be supposed, from our using this comparison between these three faculties and the Trinity, that the things compared agree in every particular, for where, in any process of reasoning, can we find an illustration in which the correspondence between the things compared is so exact that it admits of application in every point to that which it is intended to illustrate? In the first place, therefore, the similarity is found to be imperfect in this respect, that whereas memory, understanding, and will are not the soul, but only exist in the soul, the Trinity does not exist in God, but is God. In the Trinity, therefore, there is manifested a singleness [simplicitas] commanding our astonishment, because in this Trinity it is not one thing to exist, and another thing to understand, or do anything else which is attributed to the nature of God; but in the soul it is one thing that it exists, and another thing that it understands, for even when it is not using the understanding it still exists. In the second place, who would dare to say that the Father does not understand by Himself but by the Son, as memory does not understand by itself but by the understanding, or, to speak more correctly, the soul in which these faculties are understands by no other faculty than by the understanding, as it remembers only by memory, and exercises volition only by the will? The point, therefore, to which the illustration is intended to apply is this,--that, whatever be the manner in which we understand, in regard to these three faculties in the soul, that when the several names by which they are severally represented are uttered, the utterance of each separate name is nevertheless accomplished only in the combined operation of all the three, since it is by an act of memory and of understanding and of will that it is spoken,--it is in the same manner that we understand, in regard to the Father, the Son, and the Holy Spirit, that no created thing which may at any time be employed to present only one of the Three to our minds is produced otherwise than by the simultaneous, because essentially inseparable, operation of the Trinity; and that, consequently, neither the voice of the Father, nor the body and soul of the Son, nor the dove of the Holy Spirit, was produced in any other way than by the combined operation of the Trinity.
