John Gualbert

Giovanni Gualberto (c. 985 – 12 July 1073) was an Italian Roman Catholic abbot and the founder of the Vallumbrosan Order. Born into a noble family, Gualberto was a predictably vain individual who sought pleasure in vanities and romantic intrigues. When his older brother Ugo was murdered, Gualberto set out for revenge. He found the murderer in Florence, but as it was Good Friday, granted the killer’s plea for mercy. Soon after Gualberto became a member of the Order of Saint Benedict though he left in order to found his own congregation. He condemned nepotism and all simoniacal actions and was known for the pureness and meekness of his faith. Even popes held him in high esteem.
Miracles were reported at his tomb after his death. Pope Celestine III canonized Gualberto on 24 October 1193.
