Archpriest John (Ivan Nikolaevich Bukharev; 1836–1912) was a spiritual writer, teacher in Moscow schools and popularizer of the Orthodox faith. His works were intended for a wide audience, even children. The “Catechismal Teaching” contains answers to the most important questions about God and everything that surrounds him: about the holy books, about the symbols of faith, about the Lord’s prayers, about the commandments and faith in general.
