One in Three; Three in One
Accoording to the information on Wikipedia:

Within Christianity, the doctrine of the Trinity states that God is a single Being who exists, simultaneously and eternally, as a perichoresis of three persons (personae, prosopa): Father (the Source, the Eternal Majesty); the Son (the eternal Logos or Word, incarnate as Jesus of Nazareth); and the Holy Spirit (the Paraclete or advocate). Since the 4th Century AD, in both Eastern and Western Christianity, this doctrine has been stated as "One God in Three Persons," all three of whom, as distinct and co-eternal "persons" or "hypostases," share a single Divine essence, being, or nature.

To which I am tempted to say:

Huh?

Theology is incredible when it is at its height- like in that statement. Unfortunately, theology is two steps removed from experience. In essence, it is trying to put into some logical, rational, philosophical framework the explanation that was given about a powerful spiritual experience. No wonder it can be so dull and lifeless.

But it doesn't have to be. Here's a clip from a little further into the same Wikipedia article:

In the trinitarian view, the common conception which thinks of the Father and Christ as two separate beings, is incorrect. The central, and crucial affirmation of Christian faith is that there is one savior, God, and one salvation, manifest in Jesus Christ, to which there is access only because of the Holy Spirit.

So the experience that started this process is salvation- or better put- the powerful personal awareness that the God of the Universe has done something so awesome and life changing through Jesus that even after there is no material flesh and blood presence to see, a spiritual experience happens that is indescribable.

But at the heart the faith is that there is ONE God and ONLY one God. It was enough to cause the mind to melt. So, then both Jesus who showed the awesome experience in the first place and the Holy Spirit who allows us to continue to experience it must be God. But three gods?

No! Never. Absolutely not.

But I sure can't begin to describe it in any logical, sensible, rational, systematic way. I am NOT a theologian in that sense. All I do with most of my faith is to give an explanation of what it is God has been doing in my life.

And somehow remain faithful to the history that tells me that somehow, in the great mystery of God's will and work and way, Jesus and the Holy Spirit are just as much in the One God as the Creator. I know that at the depths of my heart and soul. I know it beyond knowing. I am not a worshipper of many gods, but One. God.

All else is commentary.
