Publisher's Synopsis
The Holy Father (Pope Leo XIII) exhorts priests to say this prayer as often as possible, as a simple exorcism to curb the power of the devil and prevent him from doing harm. The faithful also may say it in their own name, for the same purpose, as any approved prayer. Its use is recommended whenever action of the devil is suspected, causing malice in men, violent temptations and even storms and various calamities. It could be used as a solemn exorcism (an official and public ceremony, in Latin), to expel the devil. It would then be said by a priest, in the name of the Church and only with a Bishop's permission.
