In 1917 Our Lady appeared to three children — Lucia, Francisco, and Jacinta — and during six apparitions brought a message focusing on prayer, repentance, reparation, and sacrifice. In one of the apparitions, our Holy Mother gave the three children a vision of hell. She asked that this prayer be added to the Rosary: “Oh my Jesus, forgive us our sins, save us from the fires of hell, lead all souls to heaven, especially those most in need of thy mercy.”
An estimated 50,000 to 70,000 people witnessed the miracle of “the Dancing Sun” at the last apparition in October 1917. Modern-day cosmologists are skeptical that this miracle happened. However, these skeptics have not been able to convince the many thousands who saw this miracle firsthand and the faithful who weren’t there but still believe.
