This volume explores the neglected third person of the Trinity by examining the language, imagery and metaphors for the Spirit used by our ancestors in the faith. Dreyer sees the Spirit as crucial to the spiritual evolution and power of the laity in the 21st century, and taps male and female medieval religious voices to light the way. In the hands of these medieval authors, the Holy Spirit becomes kiss, waiter at table, reconciler, bond of love, God’s green thumb, fire, music, source of unity, intelligent Christian living and prophetic voice.
