This question has two answers, depending on what is intended.
The Church was operationally divided into two parts, the regular and the secular. The regular clergy were monastics, who were operating under monastic regulation. The secular clergy were the parish priests, bishops, and so on, who were out working with secular people.
The main body of the Church divided into two parts at the Great Schism in 1054. The western Church was Latin and centered on Rome, and this is the Roman Catholic Church. The eastern Church was Greek and centered on Constantinople, and this was the Eastern Orthodox Church. (Truth be told, however, there were always smaller independent churches, such as the Coptic Orthodox Church.)
The liturgical language used by the medieval Christian church was Latin.

The main body of the Church was split into a eastern and western parts in the Great Schism in 1054. There were other, lesser, schisms, and there were always independent branches of the Church that did not look to Rome, or Constantinople, for leadership, but the large majority of Christians were part of the Church that divided.

Pope
Most medieval Christians were Catholic and the head of the Catholic Church was the Pope. Popes were usually located in Rome, but there were times when they were in residence elsewhere. The head of the Eastern Orthodox Church, which was divided from the Roman Catholic Church in 1054, was in Constantinople. There were other church sects but they were much smaller.
