External Solemnity of the Sacred Heart
Father’s Day in the USA
The External Solemnity of the Feast of the Sacred Heart belongs by right to this day (RG 358a). As on the Feast, it is customary to have Benediction with the Act of Reparation to the Sacred Heart recited before the Blessed Sacrament exposed, the Act being that of Pope Pius XI (1928): O sweet Jesus, Whose overflowing charity for men is requited by so much forgetfulness, negligence, and contempt, etc. The Litany of the Sacred Heart is fitting recited or sung also. If the Blessed Sacrament is exposed in conjunction with the Mass, it is exposed after the completion of the Mass, not after Communion.
