…My retort then aims not at the complexity of God, but at his specific qualities. As a Catholic, you do not truly believe in a supremely simple God. You believe in a specifically Triune God, composed of 3 persons… Not (the most simple) 1 person. To follow the logic that tonyrey has been using so far, I can imagine a God composed of any infinite combination of persons, therefore God being Triune is infinitely unlikely. Therefore, God must have an ultimately simple designer.
Actually, Catholics believe that God is a trinity of persons necessarily. To provide a simple example of what I mean, consider my explanation from the previous post. As God is perfect, he cannot have contradictory or incomplete thoughts. Ergo, there cannot be multiple “Words” (or Sons) of God. And, again, as he is perfect, there cannot be any conflicts of relationship between the two. This is, I know, a simple and unsatisfactory answer. So, for your consideration, I present some of St. Thomas Aquinas’ thoughts on the matter (I call specific attention to the last paragraph):
*As God is above all things, we should understand what is said of God, not according to the mode of the lowest creatures, namely bodies, but from the similitude of the highest creatures, the intellectual substances; while even the similitudes derived from these fall short in the representation of divine objects. Procession, therefore, is not to be understood from what it is in bodies, either according to local movement or by way of a cause proceeding forth to its exterior effect, as, for instance, like heat from the agent to the thing made hot. Rather it is to be understood by way of an intelligible emanation, for example, of the intelligible word which proceeds from the speaker, yet remains in him. In that sense the Catholic Faith understands procession as existing in God…
…The procession of the Word in God is called generation. In proof whereof we must observe that generation has a twofold meaning: one common to everything subject to generation and corruption; in which sense generation is nothing but change from non-existence to existence. In another sense it is proper and belongs to living things; in which sense it signifies the origin of a living being from a conjoined living principle; and this is properly called birth. Not everything of that kind, however, is called begotten; but, strictly speaking, only what proceeds by way of similitude. Hence a hair has not the aspect of generation and sonship, but only that has which proceeds by way of a similitude. Nor will any likeness suffice; for a worm which is generated from animals has not the aspect of generation and sonship, although it has a generic similitude; for this kind of generation requires that there should be a procession by way of similitude in the same specific nature; as a man proceeds from a man, and a horse from a horse. So in living things, which proceed from potential to actual life, such as men and animals, generation includes both these kinds of generation. But if there is a being whose life does not proceed from potentiality to act, procession (if found in such a being) excludes entirely the first kind of generation; whereas it may have that kind of generation which belongs to living things. So in this manner the procession of the Word in God is generation; for He proceeds by way of intelligible action, which is a vital operation:–from a conjoined principle (as above described):–by way of similitude, inasmuch as the concept of the intellect is a likeness of the object conceived:–and exists in the same nature, because in God the act of understanding and His existence are the same, as shown above (Question 14, Article 4). Hence the procession of the Word in God is called generation; and the Word Himself proceeding is called the Son…
…There are two processions in God; the procession of the Word, and another. In evidence whereof we must observe that procession exists in God, only according to an action which does not tend to anything external, but remains in the agent itself. Such an action in an intellectual nature is that of the intellect, and of the will. The procession of the Word is by way of an intelligible operation. The operation of the will within ourselves involves also another procession, that of love, whereby the object loved is in the lover; as, by the conception of the word, the object spoken of or understood is in the intelligent agent. Hence, besides the procession of the Word in God, there exists in Him another procession called the procession of love…
…The procession of love in God ought not to be called generation. In evidence whereof we must consider that the intellect and the will differ in this respect, that the intellect is made actual by the object understood residing according to its own likeness in the intellect; whereas the will is made actual, not by any similitude of the object willed within it, but by its having a certain inclination to the thing willed. Thus the procession of the intellect is by way of similitude, and is called generation, because every generator begets its own like; whereas the procession of the will is not by way of similitude, but rather by way of impulse and movement towards an object…
…[There can be only two processions in God because] the divine processions can be derived only from the actions which remain within the agent. In a nature which is intellectual, and in the divine nature these actions are two, the acts of intelligence and of will. The act of sensation, which also appears to be an operation within the agent, takes place outside the intellectual nature, nor can it be reckoned as wholly removed from the sphere of external actions; for the act of sensation is perfected by the action of the sensible object upon sense. It follows that no other procession is possible in God but the procession of the Word, and of Love."*
