Trinity: Part Two
Monday, May 13, 2019
The all-powerful truth of the Trinity is the Father, who created us and keeps us within him. The deep wisdom of the Trinity is our Mother, in whom we all are enfolded. The exalted goodness of the Trinity is our beloved Lord: we are held in him and he is held in us. We are enclosed in the Father, we are enclosed in the Son, and we are enclosed in the Holy Spirit. The Father, the Son, and the Holy Spirit are enclosed in us. All Power. All Goodness. All Wisdom. One God. One Love. —Julian of Norwich 
Over the next few days I’ll share other writers’ perspectives on Trinity which have helped form and clarify my own thinking. Catherine Mowry LaCugna’s (1952–1997) book, God for Us: The Trinity and Christian Life, has helped to make the Trinity once again practical and participative more than mere abstract theology. LaCugna wrote:
The doctrine of the Trinity is ultimately a practical doctrine with radical consequences for Christian life. . . . The doctrine of the Trinity, which is the specifically Christian way of speaking about God, summarizes what it means to participate in the life of God through Jesus Christ in the Spirit. The mystery of God is revealed in Christ and the Spirit as the mystery of love, the mystery of persons in communion who embrace death, sin, and all forms of alienation for the sake of life. Jesus Christ, the visible icon of the invisible God, discloses what it means to be fully personal, divine as well as human. The Spirit of God, poured into our hearts as love (Romans 5:5), gathers us together in the body of Christ, transforming us so that “we become by grace what God is by nature,” namely, persons in full communion with God and with every creature. . . .
Christians believe that God bestows the fullness of divine life in the person of Jesus Christ, and that through the person of Christ and the action of the Holy Spirit we are made intimate partakers of the living God (theosis, divinization). . . .
God is not self-contained, egotistical and self-absorbed but overflowing love, outreaching desire for union with all that God has made. The communion of divine life is God’s communion with us in Christ and as Spirit. . . .
God moves toward us so that we may move toward each other and thereby toward God. The way God comes to us is also our way to God and to each other: through Jesus Christ by the power of the Holy Spirit. This is our faith, confessed in creed and celebrated in the sacraments.
Confessing faith is incomplete unless it becomes a form of life. Living faith in the God of Jesus Christ means being formed and transformed by the life of grace of God’s economy: becoming persons fully in communion with all; becoming Christ to one another; becoming by the power of the Holy Spirit what God is: love unbounded, glory uncontained.
