In addition to being the father of practically first Orthodox seminary, St. Peter used the latest technologies in the form of the printing press to mass print Orthodox literature both theological, liturgical, and apologetical, and the Orthodox Confession was among his most famous works, and thus he pioneered Orthodox Christian book publication and printing. St. Peter was the son of the prince of Moldova, and came to Rus’ from across the Carpathians, serving as a Polish knight in the Battle of Khotyn, and later became Metropolitan of Kiev and head of the Ruthenian Church at a time when Orthodoxy was in a dire position in the Polish-Lithuanian Commonwealth and was being persecuted and forced into the Union of Brest. Thanks to St. Peter’s apostolic labors, the situation completely reversed, ancient Kievan churches were restored from ruins, and he obtained a legal status for the Orthodox Church in Poland-Lithuania. He would also become the great-uncle of the future King Michael of Poland. St. Peter Mohyla’s system of education and theology influenced all Ruthenia, the Russian Empire, and even reached the new world, and for this reason, his name was called “the greatest adornment” of the Rus’ Church by historian Met. Makarius Bulgakov. His catechism was very influential especially among Ruthenians, and represents a monument of the “Ukrainian Baroque” era of theology and history, and is presented here in the famous English translation attributed to the Virginian Col. Philip Ludwell III, an associate of the American founding fathers and often called the first Orthodox Christian in America.
