Sorry for the long post. Lately I’ve been trying to wrap my mind around the Holy Trinity (at least as well as a human on this side of Heaven can). I found this talk by Venerable Fulton Sheen on youtube:
youtube.com/watch?v=gSNNmIRbRtM This lecture has helped me a great deal but a few things confused me. He suggests that one thinks of the Father as the Thinker, the Son as the Thought, and the Holy Spirit as the Love between the Two. This brought up a few questions in my mind. First of all, wouldn’t this imply a sort of hierarchy among the Members? I had always thought that each Person was equal in terms of how much each One is God. With humans at least, one doesn’t say that a thought is equally as human as the thinker. We certainly don’t call each thought a person. Also, I could understand a person loving a thought, but I never imagine a thought being able to love the thinker. Do these sources of confusion simply arise from the fact that God is infinitely more powerful than humans, and the fact that one can never explain in words exactly how the Holy Trinity functions? Or am I missing something?

Any help would be appreciated!
Well, actually, Ven bishop Fulton Sheen’s isn’t that original in this matter. St Augustine thought it first. In his book
De Trinitatae he explains this very principle. The image of the Trinity in the intellect of the human mind. He named them like this:
Mens, notitia sui, amor sui.
It works something like this. I think, aka mens (mind), of myself, aka notitia sui (the fact that I counter-pose myself), therefore, i know more about myself, and I love myself more, aka amor sui (love of self). So, I, the object, inquire about myself, the subject, therefore knowing more about the object, which is I. Knowledge=love. The more I know about something the more I can love the object. Apply this to the infinite God. The Father, from all eternity, thinks the Son, or in a more dogmatic way of saying, gives birth (generatio) to him. The Father , being God, all his thoughts are perfect in every way, so be thinking of himself, the subject of his thought is a person, the Son. Now, seeing himself in the Son, the love of the Father, which by the way is perfect, is reflected in the knowledge of himself in the Son, and this reflection of love, which by the way is perfect

, is the Holy Spirit, which is a person. This is called the act of breathing (spiratio). You will see this in Jn 20,22, when Jesus breaths the Holy Spirit upon the apostles, or when God breaths life in the nostrils of the first human. It is the same breath (spiratio), and the same Holy Spirit.
It’s very hard to explain the Trinity in human terms, without philosophy. Actually it’s impossible to fully explain or understand it, for it is the greatest mystery of our faith. Have fun wrapping your head around this.

God bless!
