In 1632 Mogila became the bishop of Kyiv and abbot of Pecherska Lavra. Because of his ties to several European royal homes, the leadership of the Orthodox clergy entrusted him to negotiate with the Polish Sejm (parliament) and the king to lift the repressive laws against the Orthodox Church and to ease the restrictions on the use of the Church Slavonic language in schools and public offices. Mogila’s diplomatic talent paid off. King Władysław IV reinstated the status of the Eastern Orthodox Church in Polish–Lithuanian Commonwealth. The first years as abbot Mogila showed that he had far-reaching goals to reform not only the monastic life at the Lavra and the Church. He wanted to strengthen the Orthodox spirituality and enhance the sense of national identity as well as raise the educational level in the country and in all Russian and Romanian lands to equal that in Western Europe.
