The Nativity of St. John the Baptist is transferred to tomorrow
On the Feast, it is obligatory to have 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. This may be done instead on the following Sunday if needed, or repeated then. The Litany of the Sacred Heart is recited or sung also on that occasion. If the Blessed Sacrament is exposed in conjunction with the Mass, it is exposed after the completion of the Mass, not after Communion
