Catholics, ortodox, protestants can you explain the trinity in this tread? Explain the trinity in the way you understand it
Catholic.
I understand the Trinity to be the belief that there exists only one eternal and infinite Creator God, the transcendent origin and first principle of all things.
This supreme reality is perfectly unitary and single in essence, being and substance; yet He relates to Himself in three subsisting relations - or instantiations - of the one divine essence to Itself.
As such, the Trinitarian aspect is not about God as he relates or reveals Himself to us but rather as He is in Himself, in his divine life: how He relates to Himself and in what ways, namely through these three eternal relations, which subsist - that is "
really exist" - in the one divine nature.
These eternal relations of origin are known distinctly as the Father, the Son and the Holy Spirit.
The Father is God as the unbegotten or unoriginate (akin to the Mind in St. Augustine's psychological analogy, that which generates thoughts and mental images), the Son is God as the generated self-image of the Father (i.e. the begotten, the knowledge with which God knows Himself, hence we also call Him
the Word) and the Holy Spirit is God as the bond of love proceeding from the two (i.e. the spirated, the love with which God loves Himself).
One God, like a perfect circle whose center is everywhere (omnipresent) and circumference nowhere (utterly transcendent and unknowable except to Himself, in the inner life of the Trinity).
So, we say that He - this singular Divine Being - is one in essence but three in "
hypostases" (subsisting relations of that one being to Himself), otherwise translated into English somewhat inarticulately as "persons".
