John Bufalari (1318?-1336?) was born in Castel Porchiano, Amelia, Italy. He is believed to be the brother of Blessed Lucy Bufalari of Amelia.
John entered the Augustinian Order while still in his teens. He was noted for his innocence, simplicity and love for his Augustinian community. He considered himself to be the servant of all, and showed great fraternal love in caring for the sick and welcoming guests to the monastery. He spent much time in prayer.
There is a story told about John crying after having spent some time in the monastery garden. Asked what was wrong, he answered that while the plants, trees and birds were obedient to God, men and women, to whom eternal life is promised, are disobedient to their creator.
John died in Rieti around the year 1336. He was only 17 years old.
His remains are preserved at Saint Augustine Church in Rieti. Pope Gregory XVI proclaimed him Blessed in 1832.
