John Calybite was a 5th-century Greek monk and hermit who lived in Jerusalem and Constantinople. After leaving his family in Rome at a young age, he spent several years living as a monk. He later returned to his birthplace disguised as a beggar, which prevented his parents from recognizing him. During this time, they provided him with a small hut to inhabit. He only disclosed his true identity to his mother while he was dying.

Born in Rome, John spent much of his life practicing monasticism. Following his time in Jerusalem, he returned to his family in secret. He lived in a simple hut provided by his parents, who remained unaware of his identity. He eventually died in Constantinople around the year 450.
Veneration
He is recognized as a saint within the Roman Catholic, Eastern Orthodox, Anglican, and Oriental traditions. His memory is honored annually on January 15. He is also referred to as the Venerable due to his monastic life.
