Our righteous father John of Kronstadt was an archpriest of the Russian Orthodox Church.

He was born as Ivan Ilyich Sergiyev in 1829. From 1855, he served as a priest in St. Andrew's cathedral in Kronstadt. Here, he wholly committed himself to charity, especially for those who were remote from the church. He established a factory to provide employment for the poor, and endlessly gave away his money to the needy.
