Here, in fact, lies the heart and the secret energy of the Church, the source of our apostolate's effectiveness. Especially in the mystery of the Eucharist, we ourselves, our priests and all our faithful can live to the full this relationship with Christ: here he becomes tangible among us, he gives himself ever anew, he becomes ours, so that we may become his and learn his love. The Year of the Eucharist and the Congress just celebrated in Bari are incentives that help us to penetrate deeper into this Mystery.
