The Angel of Portugal appeared to the Children of Fatima three times showing them how to pray this prayer bowing down to the ground using his whole body.
As the three Children of Fatima in the spring or summer of 1916 were playing on a knoll near Loca do Cabeco, the Angel of Portugal first appeared to them. Sister Lucia gave the following account:
"We had been playing for a while when a strong wind shook the trees. Since it was a calm day, we looked up to see what was happening. Then we began to see, well above the trees that covered the stretch of land to the east, a light whiter than snow in the shape of a transparent young man who was more brilliant than a crystal struck by the rays of the sun.
"As he approached, we began to see his features. He was a young man of great beauty about fourteen or fifteen years old. We were surprised and ecstatic. We did not utter a word.
"Once he drew near us, he said: 'Fear not. I am the Angel of Peace. Pray with me.' "Kneeling down, he bowed until his forehead touched the ground.
Led by a supernatural inspiration, we imitated him, and repeated the words we heard him say:
'My God, I believe, I adore, I hope, and I love Thee. I beg Thee forgiveness for those who do not believe, do not adore, do not hope, and do not love Thee.'
"After he had repeated this twice, he rose and said: 'Pray thus. The Hearts of Jesus and Mary are attentive to the voice of your supplications.' Then he disappeared.
