The exact number of these denominations is disputed, based on differing definitions used. The largest number often quoted is "approximately 45,000" from the Center for the Study of Global Christianity at Gordon-Conwell Theological Seminary. The "World Christian Encyclopedia" lists "approximately 33,000" in 2001. Yet, at the same time, the World Council of Churches counts only 348 member churches, representing more than half a billion members. This, with the Catholic Church's 1.25 billion Christians, indicates that 349 churches/denominations already account for nearly 80% of the world's Christian population.
