Major Christian Denominations and What they believe

It is said that there are over two billion Christians in the world.  However, according to TheTruthSource article Quantitative Analysis: the World (2016); although about 32% of the 7.3 billion people in the world identify with the Christian religion or 2.4 billion in 2017; only about 23% is more accurate to those that profess Christian beliefs (1.7 billion), and much less if looking at practicing Christians.  According to the Pew Research Center 2014 Religious Landscape Study, between 2007 and 2014, among the 15 largest Protestant Denominations in the USA: 8 loss membership, 5 had no growth or loss and 1 grew only .3% in 7 years.  Thus, the US like European nations is losing membership to the non-religious, while studies show Christianity growing on parts of Asia.

Every major Christian denomination proclaims its beliefs, often in what is call a ‘Statement of Fundamental Truths.’  Through Christ said, ‘whoever is not against us is for us (Mark 9:38-41);’ there can be significant differences in the beliefs and teachings of certain denominations.  These differences cause some to wonder if a few that come under the name of Christian denominations harm the Church or members of body of Christ and those to whom we reach out.  The following are charts of the top ‘Christian Denominations’ and a comparison of their beliefs; as well as a brief background of their origins.  Membership is based on stated numbers and not practicing.  By generous estimates there are about 1.1 billion that follow the Roman Catholic Church and about 700 million that fall under traditional Protestants (primarily: Anglican, Baptist, Lutheran, Methodist, and Reformed churches such as the Presbyterian); about 300 million modern Protestants (Pentecostal, Non-denominational, Seventh-day Adventists, etc.); approximately 210 Eastern Orthodox (Greek, Russia, etc.) and 75 million Oriental Orthodox.

According to Gordon-Conwell Theological Seminary, there are about 43,000 Christian denominations in the world; however the largest fall under about 20 or so major denominations.  And with tens of millions of members, even ‘non-denomination’ churches in America, such as Calvary Chapel and Vineyard, have become a denomination.   According to the World Christian Encyclopedia (2001), “World Christianity …is divided into 300 major ecclesiastical traditions, composed of over 33,000 distinct denominations in 238 countries… and 3.4 million worship centers.”  They defined ‘denomination’ as “an organized aggregate of worship centers or congregations of similar ecclesiastical tradition with a specific country.”  Two thirds are independent; about 9000 are Protestant, with another 168 Anglican; 781 Orthodox and 242 under Roman Catholic.    The largest few hundred are listed at

Brief Background

Catholic Church

(Roman Catholic Church)

Catholic (means:

‘Universal’) ‘Roman’ was not used by Second Vatican Council.





1.1 B

The Catholic Church claims its origins back to 30 AD and the disciples of Christ, and its Popes back to the Apostle Peter (Act 15, Jerusalem Council does not confirm these).  Although there were bishops of Rome at some point after Paul was imprisoned there; the Church in Rome had little strength until Emperor Constantine (about 313 AD) and the First Council of Nicaea (Nicene Creed, 325). Its leading bishops (now called popes) had no more authority than any other bishop of Europe, Asia or Africa.  It was about the 5th Century that the bishop of Rome gain authority under Leo the Great.   The four Doctors of the Western Church or ‘Fathers of the Church’ are Gregory the Great, Ambrose, Augustine and Jerome, who wrote the Latin Vulgate.

Orthodox is from the Greek orthos (right) and doxa (belief; opinion).  The Latin churches use the word Doxology (expressed belief).  The Eastern Orthodox churches were established first in Constantinople, Alexandria, Antioch, and like the Catholic Church claim Jerusalem and an origin from the disciples of Jesus Christ.  Early 4th century, the Eastern Church began to break away from the Western Church.  Papal authority was a significant factor.   The three Doctors or ‘Three Holy Hierarchs’ of the Eastern Church were John Chrysostom, Basil the Great and Gregory Nazianzen.  Although the Eastern Orthodox accepted several Councils, such as at Nicea in 325 (where most of the bishops were of the East) and three held at Constantinople, in 1054 they officially split from the Catholic (Western) Church in what is called the Great Schism.   Though the Greek Orthodox spread first, such as from Athens, Cyprus and Albania; the Russian Orthodox Church (after the baptism of King Vladimir in 988) would become the largest of the Orthodox branches.   Jesus Christ is declared in the Greek Constitution.

The Anglican (England) Church traces its roots back to when Pope Gregory of the Catholic Church sent St. Augustine to Britain and more so even back to when Christians in the army of the Roman Empire landed in Britannia in the 2nd Century AD.  England’s first church historian was the English monk Bede, who about 731 wrote the Ecclesiastical History of the English People from Julius Caesar’s 55 BC invasion to the letters of Pope Gregory about 600.  However, the Anglican Protestant church did not begin as a denomination until after its split with the Catholic Church in Rome, primed from disputes between King Henry VII (1529) and the Pope.  In 1534, Henry issued the ‘Act of Succession’ making him ‘head’ of the English Church.  Book of Common Prayer was published in 1549 and its liturgy completed in the 1662 version.   In the 1560s, Queen Elizabeth formalized the Church.  The Church of England in America was established in 1607.  The Anglican Communion is in at least 160 countries. The Episcopal Church is part of the Anglicans; the first parish in America was at Jamestown in 1607.  In 2003, they ordain the first openly gay bishop; and in 2015, by General Convention, voted to allow same-sex marriages.  In 1776 the Episcopal represented almost 16% of all religious adherents in America; after 2003 and LGBT ministers; they have continued to decline to about 1%.   At least 100,000 left to form the Anglican Church in North America (2009).
