When one starts to write about such a devotion, the first word that jumps out of the page is “heart”. The heart is, above all, the emblem of love. However, being directed to the loving Heart of Jesus, it naturally encounters whatever in Jesus is connected with this love. Now, was not his love the motive of all that Christ did and suffered? Was not all His inner, evermore than his outward, life dominated by this love? On the other hand, the devotion to the Sacred Heart, being directed to the living Heart of Jesus, thus becomes familiar with the whole inner life of the Master, with all His virtues and sentiments, finally with Jesus infinitely loving and lovable. Hence, first extension of the devotion is from the loving Heart to the intimate knowledge of Jesus, to His sentiments and virtues, to His whole emotional and moral life; from the loving Heart to all the manifestations of Its love. There is still another extension which, although having the same meaning, is made in another way, that is by passing from the Heart to the Person, a transition which, as we have seen, is very naturally made. When speaking of a large heart our allusion is to the person, just as when we mention the Sacred Heart we mean Jesus. This is not, however, because the two are synonymous but when the word heart is used to designate the person, it is because such a person is considered in whatsoever related to his emotional and moral life. Thus, when we designate Jesus as the Sacred Heart, we mean Jesus manifesting His Heart, Jesus all loving and amiable. Jesus entire is thus recapitulated in the Sacred Heart as all is recapitulated in Jesus.
