Sub-Subject Description: Denominations of Christianity.

Like almost all religions, Christianity is not a homogeneous block.

Throughout its 2,000 years of history has experienced three major schisms, forming the three major Christian denominations: Catholics, Protestants, and Orthodox


Roman Catholicism, based in Rome, represents 50% of all Christendom. It is the majority in the Central and Southern Europe, Ireland, and South America.

The Catholic Church has 1,100 million adherents worldwide, representing half of the World's Christian Population. Brazil has the largest number of Catholics in the World (134 million). There are more Catholics in Brazil than in Italy, France, and Spain together.

The ten countries with the largest number of Catholics (Brazil, Mexico, the Philippines, the United States, Italy, Colombia, France, Poland, Spain, and Congo DR) contain more than half (56%, 607 million) of the World's Catholics.

There are sixty-seven countries where Catholics are the majority of the population. Over 70% of Catholics live in the Americas (48%) and Europe (24%). Nearly 40% live in Latin America and the Caribbean. More than a quarter of Catholics lives in the Region of Asia-Pacific (12%) and Sub-Saharan Africa (16%).


The 801 millions of Protestants in the World constitute 37% of the World's Christian Population. The Protestant Reformation, which divided Western Christianity and gave birth to Protestantism, took place in Europe in the sixteenth century. Today, however, only two of the ten countries with the largest Protestant populations are European: the United States, Nigeria, China, Brazil, South Africa, the United Kingdom, the Democratic Republic of the Congo, Germany, Kenya, and India.


There are 260 million Orthodox Christians, who make up 12% of the World's Christian Population. Almost four in ten Orthodox Christians around the world (39%) reside in Russia, the country with the largest number of Orthodox. Ethiopia has the second-largest number of Orthodox.

All other Christian traditions (Mormons, Jehovah's Witnesses) represent 1% of all Christendom.

Number of Christians in the World by continent (Data in million):

  1. America: 804
  2. Europe: 565
  3. Africa: 516
  4. Asia-Pacific: 285

Christianity became the official religion of the Roman Empire in 380. Until 1054, Christianity formed a monolithic block (except small movements as Nestorians). That is, about half of its history, 1000 years, Christianity has been unitary.

As we will see in the units on Orthodoxy, Catholicism, and Protestantism, in the 11th century occurs the division between Catholicism and Orthodoxy. In the 16th century occurs Luther’s reform which will lead to Protestantism.
