About John Gualbert
Lived 995 – 1073 (aged 77–78). John Gualbert was a religious.
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.
Life Giovanni Gualberto was born circa 985 to nobles who hailed from the Visdomini house; he was born in the castle known as Poggio Petroio. When his brother Ugo was murdered, Gualbert set out to avenge his death.
One Good Friday as he was entering Florence with his armed followers, he happened, in a narrow lane, to come upon the man who had killed his brother. The killer fell upon his knees with arms outstretched in the form of a cross and begged for mercy in the name of Jesus, reminding Gualbert that Christ had died on that day. Gualberto granted him mercy and renounced his revenge.
Gualbert entered the Benedictine church at San Miniato al Monte to pray and the figure on the crucifix is said to have bowed its head to him in recognition of his generous and merciful act. Gualbert begged pardon of his sins and that week cut off his hair and began to wear an old habit that he had borrowed. This tale forms the subject of Burne-Jones's picture "The Merciful Knight" and Shorthouse adapted this in "John Inglesant".
Veneration Gualbert was canonized by Pope Celestine III on 24 October 1193.
His liturgical feast was not included in the Tridentine calendar but was later added to the General Roman Calendar in 1595. Owing to its limited worldwide importance his feast was removed from that calendar in 1969. The date assigned for his feast still remains as indicated in the Roman calendar and according to the new rules given in the Roman Missal in 1969 could still be celebrated across the globe with his own Mass unless in some places an important celebration is assigned and thus coincides.
The Benedictines observe his day as an Optional Memorial.
Gualberto is the patron saint for foresters and also is the patron for park rangers and parks. Pope Pius XII named him – in 1951 – as the patron saint for the Italian Forest Corps while he was named as the patron for Brazilian forests in 1957.
