The Sacred Heart of Jesus Christ is a symbol of a Catholic's devotion to reciprocating Christ's love for mankind as God and man. The devotion simultaneously affirms the bodily incarnation of the Lord who has a human heart and human emotion, with His Divine Love and Mercy, in the unity of His Person as truly having both divine and human natures. It is devotion to His resurrected and glorified human heart as being also the human heart of God. It is returning love for love by embracing the gift of His promise of Salvation through devotion, atonement and reparation. The Feast of the Sacred Heart is celebrated on the Friday 19 days after Pentecost. The earliest possible date is May 29, as in 1818 and 2285. The latest possible date is July 2, as in 1943 and 2038.
Along with The Litany of all Saints, the Litany of Loreto, the Litany of the Most Holy Name of Jesus Christ, and the Litany of St. Joseph, the Litany of the Sacred Heart is one of five litanies approved by the Holy See to be recited at public celebration.
