Devotion to the Sacred Heart, thus understood, is a manifestation in the Church of the Holy Spirit, "helping us in our weakness; for we do not know how to pray as we ought" (Rom 8:26).5 The Sacred Heart is, in the life of the Church, the organ by which "the Spirit intercedes for the saints according to the will of God" (Rom 8:27).
Cardinal Ratzinger wrote: "We see who Jesus is if we see him at prayer. The Christian confession of faith comes from participating in the prayer of Jesus, from being drawn into his prayer and being privileged to behold it; it interprets the experience of Jesus' prayer, and its interpretation of Jesus is correct because it springs from a sharing in what is most personal and intimate to him".6
This is the prayer of the Sacred Heart, the prayer that filled the days and nights of Jesus' earthly life, the prayer that suffused his sufferings and ascended from the Cross at the hour of his death, the prayer that with him descended into the depths of the earth, the prayer that continues uninterrupted in the glory of his risen and ascended life, the prayer that is ceaseless in the Sacrament of the Altar....
The prayer of the Heart of Christ at the hour of his sacrifice passes entirely into the heart of the Church, where it is prolonged and actualized "from the rising of the sun to its setting" (Mal 1:11) in the Liturgy of the Hours and in the mystery of the Eucharist.
Cardinal Ratzinger asks if, after the once-for-all Pasch of Jesus, anything more is needed. "After the tearing of the Temple curtain and the opening up of the heart of God in the pierced heart of the Crucified, do we still need sacred space, sacred time, mediating symbols? Yes, we do need them, precisely so that, through the 'image', through the sign, we learn to see the openness of heaven. We need them to give us the capacity to know the mystery of God in the pierced heart of the Crucified".14
It is through the liturgy, first and above all, that we pass over into the prayer of the Sacred Heart, the word to the Father forever inscribed in his pierced side. (Read entire post.)
