Today in Garabandal History: July 31, 1961.

The Girls Recite the Rosary in unison before they knew or learned it (recorded).

For the first time, the Visionaries in ecstasy move about on their knees. They recite the Rosary without having learned it, without prayer beads, without counting on their fingers and without making any mistakes regarding the mysteries, as well as the number of "Ave Marias". (This was proof that Mary was teaching them in their vision)
