John the Laz

John the Laz (; fl. 5th century) was a Georgian eunuch official (cubicularius), monk and theologian of early Christianity and one of the key figures of monasticism in the Palestinian region. He was a tutor, life-long fellow and possible godfather of Peter the Iberian.

Life John was born as Mithridates in the region of Lazica, part of the Kingdom of Iberia during the reign of Vakhtang I. Mithridates was most probably a eunuch and chamberlain at the Roman royal court. He changed his name after he became a monk following his ordination. John, moved by the example of Saint Passarion of Palestine, he and his adept, another Georgian by birth, Peter the Iberian, whom he met in the Great Palace of Constantinople, decided to escape to Jerusalem and organize a monastery with a shelter for poor pilgrims, where they would engage in "uninterrupted praise and warship of God". They chose the place near the Tower of David. Per Vita Petri Iberi, "blessed fathers Peter and John went to the deserted place near the Jordan River, and built a monastery there". When a dispute arose with the neighbor concerning the monastery's property line, words came to blows, and neighbor punched John in his face. In c. 444, John, with Peter left Jerusalem for Gaza. Peter soon became a bishop of Gaza. John had a weak physical health and suffered from skin disease. He was affected with kind of herpes that broke out on his whole face. Peter, worried about his friend's health, took John to the Church of the Holy Sepulchre. Peter and John knelt down and prayed all night with "bitter tears and groans", and eventually, at dawn, John's face was completely cured with the "devine power of the holy cross".

John died in either 463 or 465. He was buried in a Georgian monastery, but it is unclear, whether in Jerusalem or in the Judean Desert, nearby Bir el Qutt, where the Georgian inscriptions were unearthed. Per Vita, John was buried in Peter's monastery between Gaza and Maiuma, where his regular commemorations were celebrated as well. Peter died in 491 in Jamnia; his disciples buried him next to John the Laz.
