The Holy Face devotion was first heard of through a Carmelite Nun named Sister Mary of St. Peter in France, 1844, who stated Our Lord revealed this devotion to her at Mount Carmel. Sister Mary of St. Peter stated that Our Lord wanted this devotion to be spread throughout the world with the goal of making reparation for the sins which offend God.

When a man named Leo Dupont took this devotion and started practicing it privately in his home nearby, repeated first class miracles started occurring, which lasted for a period of over 30 years! This immediately became the talk of France, and attracted the attention of the Catholic Church, who investigated and publicly recognized the miracles as authentic. These miracles attest to the authenticity of the revelations from Our Lord to Sister Mary of St. Peter.

In 1885, to bring attention to the importance of this devotion, Pope Leo XIII established this special devotion as an Archconfraternity; and contrary to custom, He immediately established it for the ENTIRE WORLD. Note that numerous indulgences have been granted from several Popes, including Pope Pius IX and Pope Leo XIII, to those devoted to Devotion to the Holy Face of Jesus. Here are copies of the actual papal briefs by Pope Leo XIII in 1885:

First Papal Brief (December 16, 1884)
Second Papal Brief (April 22nd, 1885)
Third Papal Brief (October 1, 1885)
Indulgences Granted by Pope Leo XIII

Note that Saint Therese of Lisieux was also very dedicated to this devotion, which prompted to take the name, “Therese of the Child Jesus and of the Holy Face”. This devotion was universally practiced before World War I but unfortunately, has since become scarcely known. This website has been created in an attempt to revive this important devotion.
