Saint John was born in 1829 in northwestern Russia. He became a priest at 36 years of age, serving in the Church of Saint Andrew in Kronstadt, Russia. He was known for his commitment to the poor and those in need and was heavily involved in charity work. He travelled throughout Russia, helping many in need, and eventually became well known around the country. Enlightened by the Holy Spirit, he prophesied the Russian Revolution in 1917. He fell asleep in peace in 1908.

Saint John’s feast day is celebrated on December 20.
