I am over here at an unusual time for me just to post this which is from The Life of Sister Mary of St. Peter (1884 rev'd.)which you can easily find in pdf but can't buy. You can buy though The Holy Man of Tours (1882 original pub.), on holyface.com.
This came as you will see at the end of a period of time Our Lord used to focus on just this one angle of the Holy Face.
This, summarizes everything!
I have found that the Holy Face medal even w/o the pamphlet but I usually give the pamphlet is the most readily received among a variety of people. Several on the street; a bunch of colleagues in public school via the mail after I quit the job of teaching special education. This reading of this book, and all the prayer thus far developed impossible to have with 15 hour days 6 days a week. ;D Relatives get to see what Catholic devotion is like. Fallen far away Catholics... I don't know what they do but it does come from their heritage and they are old enough to have experienced pre 1958.
Anyway... this is fantastic! I like this site: holyfacedevotion.com basically a little better than holyface.com because it has a lot of detail and you can find a lot there, if you look. From the book with a little preamble:
At the termination of these communications which unveil to Christian piety so vast and so luminous a horizon, Sister St. Peter had an interior vision on the same subject, October 30th, which sublime conceptions she expressed in the following terms:
"Remember, my soul, the instruction which thy celestial Spouse has given thee today on his adorable face: rember that this divine Chief represents the Father who is from all eternity, that the mouth of this Holy Face is a figure of the Divine Word, engendered by the father, and that the eyes of this mysterious Face represent the reciprocal love of the Father and the Son; for these eyes have bu one and the same light, the same knowledge, producing the same love, which is the Holy Ghost in his beautiful silken hair contemplate the infinitude of the adorable perfections of the most holy Trinity; that the eyes of this mysterious Face represent in this majestic head, the most precious portion of the sacred humanity of thy Saviour, contemplate the image of the unity of God."
