88 Each and all of you, then, from the recollection and prayer of a retreat will come out fortified against the snares of the world, quickened by lively zeal for the salvation of souls, and enkindled with the love of God, as befits priests in times like the present. For together with so much corruption and diabolical malice, there is everywhere felt a powerful religious and spiritual awakening, a breath of the Holy Spirit, sent forth over the world to sanctify it, and to renew with its creative force the face of the earth. Filled with the Holy Ghost you will communicate this love of God like a holy fire to all who approach you, becoming in a true sense bearers of Christ in a disordered society, which can hope for salvation from Jesus Christ alone, since He, and He alone, is ever "the true Savior of the world."
