From the Bible to Pope Benedict XVI, and drawing from literatures in half a dozen languages, Werner Jeanrond tracks the development of Christian thinking about love, its varieties and its controversies. This is far more than mere history, however, since through it runs a salutary, ecumenical argument for transcending the Lutheran dichotomy between divine agape and human eros, so as to recover the creative calling and potential of human love. Nor is it just about ideas, but also about the institutions--family, marriage, friendship, church--which can cultivate the praxis of love in a culture whose individualism has kicked away so many social supports. "A Theology of Love" is a broad education, characteristically generous in spirit, rich in substance, and refreshingly uncluttered in style.
