There is a limit to what the human mind can reason for God in revealing to us the truth about himself. Be content with simply telling us what the truth is. There are three divine Persons - Father, the Son and the Holy Spirit . there is only one divine nature but there are three divine persons
When we try to think of God as three Persons possessing one and the same nature, we find ourselves battling our heads
Is is why we call such truths that the blessed trinity a mystery of faith. We believe it is so because God say it is so
Theologians do of course cast some light upon the mystery for us. They explain that the distinction between the three Persons in God is based upon the relationship that exists between three Persons There is a difference between our knowledge and God’s knowledge of himself. It is of the very nature of God to exist. The only real definition we can give God is to “ he is who is” like to Moses “ I am who am”
God sees of himself. God the Father is God knowing himself
God the Son is the expression of God knowledge of himself. Son is the expression of God knowledge of himself thus the second Person of the blessed trinity, the son of God precisely because from all eternity he is generated he is begotten in the divine mind of the father. Also the silent word he perfectly express himself, whom we call God the Son. He is also called the word of God because he is the mental word in which the divine mind gives utterance to the thought of himself
Nature of God must be a living love and infinitely intense living love which flows externally from father and Son is he whom we call the Holy Spirit.
- God the father God knowing himself
- God the Son is the expression of Gods knowledge of himself
- God the Holy Spirit is the result of Gods love for himself
Example of Trinity in best possible human reasoning:
Lets use a full length mirror. You see there an image of yourself, a living image but it is just an reflection in the glass. There would no be two of you, there would be just one you, one human nature. There would be two persons but only one mind and one will, sharing the same knowledge and same thoughts. The self-love is natural to an intelligent being, there would flow between you and your image an ardeen love. This love would be a third person standing between you and your image.
Even if these remarks or example don't help, we should not get frustrated when dealing this mystery of faith. However one error must guard, must not think God the Father came first, God the Son or Holy Spirit later. All three equally eternal, equally timeless with God's nature and also God the Son and Holy Spirit are not in anyway subordinate to God the Father.
We can attribute individual divine Persons certain works such as God the Father for work of creation or the generator, the Son of God's work to make know the truth on earth for all of us and heal. and finally Holy Spirit works of sanctification of souls
