Question about act of reparation

A member has asked for clarification about what form the act of reparation for past wrongs should take when visiting former Catholic places of worship. There is nothing to stop members using any suitable and approved form of act of reparation but the following advice is given on the SSIM website:

On visiting a church, monastery, shrine, even if ruined, which had previously been used for Catholic worship recite the following [Pater Noster, Ave Maria and Gloria Patri] for the repose of the souls of all who have worshipped there in the past, especially the priests who faithfully offered the holy sacrifice of the Mass and in reparation for all wrongs committed there. Pray also for the unity of Christ’s church around the See of Peter and for the intentions of our Holy Father
