In this insightful work, the author explores the fundamental Christian virtue of 'agape.' Spicq's genius is the way he combines fine linguistic analysis, exegesis, and theological insight. The three volumes cover most of the New Testament books:

Volume 1: 'Agape in the Synoptic Gospels'
Volume 2: 'Agape in the Epistles of St. Paul, the
Acts of the Apostles, the Epistles of
St. James, St. Peter, and St. Jude'
Volume 3: 'Agape in the Gospel, Epistles and
Apocalypse of St. John'

The word 'agape,' in particular, had acquired so specialized and rich a meaning that it seemed almost a neologism. . . . The final word of the mystery of God and the source of the Christian life is always love. Everything is summed up in love.
