This work recounts the life and revelations of Sr. Mary of Saint Peter, through which Our Lord communicated the devotion to His Holy Face and the powerful prayer called the Golden Arrow for reparation of blasphemy and sanctification of souls. Rooted in authentic Catholic devotion that was later approved and promoted by Pope Leo XIII and saints such as St. Thérèse of Lisieux, it invites the reader to embrace reparation and deeper adoration of Christ’s sacred countenance in prayer and daily life.
