In this profound and illuminating work, Joseph Cardinal Ratzinger turns the gaze of an accomplished theologian upon the crucified Savior. This synthetic and meditative work is theological without being abstract or dry, and spiritual without being sentimental. The pierced heart of Christ must be the heart of theology and Christian life as well.

Proceeding from the prayerful dialogue between the Incarnate Son and his Eternal Father, Joseph Ratzinger shows how one can approach the mystery of the Heart of Christ only through the imitation of this prayer. To know and understand Jesus we must participate in his prayer. The prayer of Christ must be the interior life of all who are joined to him in his Body, the Church. Using the Old and New Testaments and the Church Fathers, Ratzinger shows that the ecclesial community (the Church) was born from the pierced Heart of Christ on the Cross.
