208 Saint Paul VI , addressing religious Congregations dedicated to the spread of devotion to the Sacred Heart, made the following observation. “There can be no doubt that pastoral commitment and missionary zeal will fan into flame, if priests and laity alike, in their desire to spread the glory of God, contemplate the example of eternal love that Christ has shown us, and direct their efforts to make all men and women sharers in the unfathomable riches of Christ”. As we contemplate the Sacred Heart, mission becomes a matter of love. For the greatest danger in mission is that, amid all the things we say and do, we fail to bring about a joyful encounter with the love of Christ who embraces us and saves us.
