Why study the nature and implications of the Trinity

It is a key essential doctrine of the historic Christian faith - salvation lies on its assertion. Learning more of the doctrine helps us learn more of the God who is indeed Trinity.

I can teach us about:

The oneness and unity of God (with implications for unity in the Church).
The diversity of God (with implications for diversity in the Church).
The holiness, jealousy, and wrath of God.
The Lordship and Divinity of Jesus Christ.
The deity and work of the the Holy Spirit.
The role of the Father, Son, and Spirit in the life of the believer and the Church.
The Nature the Church (reflects the nature of the Trinity)
The mission of the Church (reflects the mission of the Trinity)
Love (as the essence of who God is).
Community (Trinity as ultimate model of community).
Relationships (God is relational, so are we).
Mutual submission (reflects the inner dynamic of the Trinity).
Interdependence (reflects the inner dynamic of the Trinity).
The Nature of Marriage (reflects the intimacy within the Trinity).
Etc, etc, etc.

Really, the list can go on and on.

Really now, why study and read up on the Trinity!? Indeed!

Update: Professor John Stackhouse of Regent College has some thoughts on the implications of the Trinity for the gender debate....which is, not a lot. (HT to Bryan L).
