In the mystery of the Unity and Trinity of God we believe that, from all eternity and before material creation and even outside of time itself, the One God who desired a perfect communion of love expressed Himself in a perfect Word, containing all that He is. The Word God uttered was and is a perfect self-expression, also perfectly possessing what the Speaker possesses: being, omniscience, omnipotence, truth, beauty, and even personhood. So, from all eternity there were always two divine Persons, the God who spoke and the Word who was spoken, the God who Generates and the God who is Generated, true God with and from true God, Begetter and Begotten, Father and Son. There was never a time when this was not so. These two Persons eternally regard and contemplate each other. From all eternity they knew and loved each other, each offering the other a perfect gift of self-giving. Since the self-gift of these perfect and divine Persons, distinct but sharing one divine nature, can be nothing other than a perfect self-gift, perfectly given and perfectly received, the very Gift between them also contains all that each of the Persons have: being, omniscience, omnipotence, truth, beauty, and even personhood. Therefore, from all eternity there exist three distinct divine Persons having one indivisible divine nature, Father, Son and the perfect self-gift of love between them, the Holy Spirit.
I don’t find this helpful at all. “The God who spoke and the Word who was spoken”. Of course it is a symbolic analogy but what does “spoke” mean? How can it be an eternal event? And how can the spoken Word be a distinct and eternal person? And how can the "self-gift of love between them also be a person? How can love be a person.
I don’t know the true nature of the Trinity other than to think of it as a family. Three persons in the diving family.
