This is especially important concerning the recent death of Fr. Gruner, the Apostle of Fatima. If you never read his book "Crucial Truths to Save Your Soul" then you must. It is a short, inexpensive book that I am highly recommending.
On this Vigil of the Ascension, this Rogation Day, and this anniversary of this apparition, let us pray for Fr. Gruner's soul and for all peoples to convert, do penance, and appease the wrath of God. Let us say with true and heartfelt devotion:
O my Jesus, forgive us our sins, save us from the fires of hell, and lead all souls to Heaven, especially those in most need of Thy mercy.
