The "Sagrado Corazón de Jesús," or Sacred Heart of Jesus, is a Christian symbol representing the love and compassion of Jesus Christ for humanity. It is often depicted as a heart surrounded by thorns, symbolizing the suffering of Christ, and is usually shown with flames, representing divine love. This devotion is particularly significant in the Catholic Church and is celebrated through various feasts and prayers. The devotion to the Sacred Heart has its roots in the Middle Ages but became more formalized in the 17th century through the visions of Saint Margaret Mary Alacoque. The feast of the Sacred Heart is celebrated on the Friday following Corpus Christi, emphasizing the importance of Jesus' love and mercy in the lives of believers.
