Catholice fidei defensionem
From Wikipedia, the free encyclopedia
Catholice fidei defensionem is a papal bull issued by Pope Innocent VIII on 12 July 1486 granting plenary indulgences to those who took part in Casimir IV Jagiellon's war against the Ottoman Empire.[1]

The Church of the Holy Cross, Pătrăuți, opened by Stephen the Great in 1487, contains a painting of a procession of the saints to find and raise the Holy Cross. Recent scholarship has demonstrated a link between this painting and the bull.[2]
