In short: Born in Kiev, Theophan Prokopovich traversed Europe, absorbing Catholic, Protestant, and scientific thought before returning home. As the trusted intellectual engine behind Peter the Great, he dismantled the church patriarchate, replaced it with a state-controlled synod, and fundamentally reshaped Russian theology, preaching, and education with a modern, historical perspective.

Theophan Prokopovich, born Eleazar in 1681, was a polymath whose life spanned the intellectual currents of 17th and 18th-century Europe. After his early education at the Academia Mohileana in Kiev, he traveled to Rome, where he studied at the Catholic Academy of St. Athanasius. This period proved pivotal; he gained access to the Vatican Library and engaged with the works of figures like Galileo Galilei, Giordano Bruno, and Nicolaus Copernicus. His intellectual journey continued through France, Switzerland, and Germany, where he encountered the ideas of the Protestant Reformation, eventually leading him to renounce Catholicism and return to the Orthodox faith in 1704.

Prokopovich’s rise to power was cemented by his oratorical skill. In 1711, his sermon commemorating the Battle of Poltava so impressed Tsar Peter I that he was appointed rector of the Kiev-Mogila Academy. There, he initiated a radical pedagogical shift, replacing the traditional Orthodox scholastic system with the historical methods favored by German theologians. This intellectual rigor made him an essential ally to the Russian state, which sought to modernize its institutions.

As the primary author of the spiritual regulation, Prokopovich orchestrated the most significant restructuring of the Russian Orthodox Church in centuries. By establishing the Holy Governing Synod in 1721—a body he led as vice-president—he effectively abolished the office of the patriarch, bringing the church under civil administrative control. Despite facing intense opposition from clergy who viewed him as an interloper and a semi-heretic, he remained a tireless reformer. Until his death in 1736, he worked to purge the church of what he deemed superstitions, introducing a simpler, more accessible style of preaching that left a lasting mark on the Russian language.
