Book excerpt: Tanner offers not a repetition of doctrines but a creative synthesis of key Christian principles - especially the transcendence and gift-giving of God - and contemporary experience. What emerges is a profound yet precise vision of creation, God's life, and our participation in it. While consonant with traditional teachings, Tanner's dynamic speculative theology is universal in its range, mystical in its outlines, and deeply ethical in its relations with all God's gifted creatures. Jesus, Humanity, and the Trinity not only takes stock of Christian belief in a time of tumultuous intellectual and cultural change. It also finds in that ferment a life-giving meaning and mission for Christian life.
