Marian Apparitions to Popes According to the Dictionary of Apparitions of the Virgin Mary, throughout history only 6 popes have witinessed apparitions of the Virgin Mary. The weakness and insufficiency of the sources do not permit appropriate discernment. Here is the chronological list: • Pope Liberius (356) • John I (Saint, †526) • Honorius III (1227) • Honorius IV (1210 - 1287) • Celestine V (Saint, 1215-1296) • John XXII (†1245-1334) • Callisto III (1378-1458) Noteworthy: According to his entourage, Pius XII (1958) witnessed in 1950 a miracle of the sun, but never saw an apparition. Apart from this, there is no modern Pope or contemporary figure in this list. Pius V (1504 - 1572) and Pius X (Saint) or John XXIII are absent. Marian apparitions to Popes are officially approved by definition as there is no higher authority to rule on their authenticity. Source: Laurentin, Rene and Sbalchiero, Patrick.
