Venerable Zosimas of Palestine, also called Zosima, is commemorated as a saint in the Eastern Orthodox and Byzantine Catholic Churches on April 4. Saint Zosimas was born in the second half of the fifth century, during the reign of Emperor Theodosius the Younger. He became a monk in a monastery in Palestine at a very young age, gaining a reputation as a great elder and ascetic. At the age of fifty-three, now a hieromonk, he moved to a very strict monastery located in the wilderness close to the Jordan River, where he spent the remainder of his life.
