In general, reparation means repairing or making up for
damages done. In a spiritual sense, we sinners make reparation for our
sins and the sins of others through voluntary acts of penance or works of piety and devotion
done in the spirit of reparation.
To make reparation for acts of blasphemy and profanity,
Catholics recite the divine praises ("Blessed be God, Blessed be his holy name," etc.),
especially after Benediction of the Blessed Sacrament.
Devotion to the Sacred Heart of Jesus, as promoted by St.
Margaret Mary Alacoque, calls for prayers and acts of reparation as well as Communions
(especially on First Fridays) received in the spirit of reparation and atonement.
