All that we have said has implications for the spiritual life. For example, the theology underlying the Spiritual Exercises of Saint Ignatius Loyola is based on “affection” ( affectus). The structure of the Exercises assumes a firm and heartfelt desire to “rearrange” one’s life, a desire that in turn provides the strength and the wherewithal to achieve that goal. The rules and the compositions of place that Ignatius furnishes are in the service of something much more important, namely, the mystery of the human heart. Michel de Certeau shows how the “movements” of which Ignatius speaks are the “inbreaking” of God’s desire and the desire of our own heart amid the orderly progression of the meditations. Something unexpected and hitherto unknown starts to speak in our heart, breaking through our superficial knowledge and calling it into question. This is the start of a new process of “setting our life in order”, beginning with the heart. It is not about intellectual concepts that need to be put into practice in our daily lives, as if affectivity and practice were merely the effects of – and dependent upon – the data of knowledge. 16Cf. MICHEL DE CERTEAU, L’espace du désir ou le «fondement» des Exercises Spirituels: Christus 77 (1973), pp. 118-128.
Where the thinking of the philosopher halts, there the heart of the believer presses on in love and adoration, in pleading for forgiveness and in willingness to serve in whatever place the Lord allows us to choose, in order to follow in his footsteps. At that point, we realize that in God’s eyes we are a “Thou”, and for that very reason we can be an “I”. Indeed, only the Lord offers to treat each one of us as a “Thou”, always and forever. Accepting his friendship is a matter of the heart; it is what constitutes us as persons in the fullest sense of that word.
Saint Bonaventure tells us that in the end we should not pray for light, but for “raging fire”. 17Itinerarium Mentis in Deum, VII, 6. He teaches that, “faith is in the intellect, in such a way as to provoke affection. In this sense, for example, the knowledge that Christ died for us does not remain knowledge, but necessarily becomes affection, love”. 18ID., Proemium in I Sent., q. 3. Along the same lines, Saint John Henry Newman took as his motto the phrase Cor ad cor loquitur, since, beyond all our thoughts and ideas, the Lord saves us by speaking to our hearts from his Sacred Heart. This realization led him, the distinguished intellectual, to recognize that his deepest encounter with himself and with the Lord came not from his reading or reflection, but from his prayerful dialogue, heart to heart, with Christ, alive and present. It was in the Eucharist that Newman encountered the living heart of Jesus, capable of setting us free, giving meaning to each moment of our lives, and bestowing true peace: “O most Sacred, most loving Heart of Jesus, Thou art concealed in the Holy Eucharist, and Thou beatest for us still… I worship Thee then with all my best love and awe, with my fervent affection, with my most subdued, most resolved will. O my God, when Thou dost condescend to suffer me to receive Thee, to eat and drink Thee, and Thou for a while takest up Thy abode within me, O make my heart beat with Thy Heart. Purify it of all that is earthly, all that is proud and sensual, all that is hard and cruel, of all perversity, of all disorder, of all deadness. So fill it with Thee, that neither the events of the day nor the circumstances of the time may have power to ruffle it, but that in Thy love and Thy fear it may have peace”. 19SAINT JOHN HENRY NEWMAN, Meditations and Devotions, London, 1912, Part III [XVI], par. 3, pp. 573-574.
Before the heart of Jesus, living and present, our mind, enlightened by the Spirit, grows in the understanding of his words and our will is moved to put them into practice. This could easily remain on the level of a kind of self-reliant moralism. Hearing and tasting the Lord, and paying him due honour, however, is a matter of the heart. Only the heart is capable of setting our other powers and passions, and our entire person, in a stance of reverence and loving obedience before the Lord.
