The following quote comes from “The Fatima Rosary Prayer – How was the Fatima Rosary Prayer so mistranslated?”, from the sisterlucytruth.com website (in which the link to said webpage is also found below):
“Portuguese Language Friends of Sister Lucy Truth have uncovered the research that discovered the correct and original text of the “Oh my Jesus” prayer, that was meant to be placed at the end of each decade of the rosary. This prayer was revealed by Our Lady after the Vision of Hell was given to the three children on July 13, 1917.” – From sisterlucytruth.com
