Well, we don't have to call it 3, see. Neither do we have to call it trinity. I call father, son, and holy spirit, the MEANS. The means for what? The means to reach, to pursue his children in the dark places he knows they will go. It's the heart for them, the love for them, the means to fill each one of them with himself. How far back does that go? Does it have a beginning?
Yahoo! have you ever come across the phrase "economic Trinity"?
In Patristic teaching, there is a distinction between the 'economic Trinity' and the 'ontological Trinity' — Athanasius speaks of the '
oikonomia' and the '
theologia' (although I've always found the terms are rather confusing!).
Oikonomia derives from
oikos, 'house' +
nemein 'management'. In short, good housekeeping.
In theological terms, 'Economical-Trinity' is God's revelation of His plan for creation and, as it turned out, its salvation. In that sense it's God's activity in the world.
Again, in theological terms, the 'Theological-' or 'Immanent-' or 'Ontological-Trinity' is God in Himself, the Isness of the Divine, the idea that for there to be God and the World, as it were, there must to be the
principle of Unity within the One-ness. If there were not, there would only be God in and to Himself, and nothing else.
"Theology" refers to being within the Trinity and "economy" to the works of the Trinity by which God reveals and communicates Himself.
As the Catechism says, it's through the
oikonomia that the
theologia is revealed to us; but conversely, the
theologia illuminates the whole
oikonomia. God's works reveal who he is; the mystery of His inmost being enlightens our understanding of all His works.
Scripture says God is love, but for 'love to be in its fulness, there has to be subject, object, and that which unties, there has to be the Lover, the Loved, and the Love they have in common. Something can't love nothing, If God was all there is, there would be no Love.
The
Trinity Oikonomia is the exoteric teaching, the
Trinity Theologia is the esoteric teaching. But they are both one and the same Trinity, one in time, one in eternity.
