Christianity is the world’s most popular religion – with over 2billion followers. Christianity is the main religion in Northern America, South America, Europe, and parts of Australasia and Africa. Christianity has recently been seen as a religion that acts as a bastion of peace – though tragically, Christians are officially the most persecuted people worldwide.

With over 2billion followers, it is understandable that not all Christians follow exactly the same beliefs. Therefore, different denominations exist. While some denominations feature thousands of Churches, others operate on a small scale.

Denominations typically differ from one another due to stances on the likes of the infallability of the Bible, the nature of sin, abortion, homosexuality, the Holy Trinity, the after-life and assisted suicide among other areas. In this article, we take a look at the ten biggest Christian denominations worldwide.

For the basis of clarity, please note that we have not considered Protestantism to be one denomination – rather, we have used the array of denominations that make up Protestantism. There are around 900M Protestants worldwide. The same logic, though in reverse, has been used for Catholicism, Eastern Orthodoxy, and Oriental Orthodoxy, with each of these considered as one large denomination.

Finishing just outside the top 10 is the Latter-Day Saints denomination, better known as Mormons. Arguably the most misunderstood denomination of all, the Latter-Day Saints Movement, spearheaded by Joseph Smith in the 1800s, now has around 16.5million members. The biggest Church in this movement is the LDS Church.

Among the kindest people you’ll ever meet, those in the LDS Church are always happy to share their gospel with others, have general religious discussions, and more. Now though, we advance to the top 10.

10th: Seventh Day Adventists – 21million

A rapidly growing Church is the Seventh Day Adventists. They are known for their belief that Saturday is the day that should be observed as the day of worship. They also believe that the dead will resurrect, and that the Second Coming of Jesus is imminent.

They also place importance on the trinity, importance of faith, God’s creation of the world in seven days, and, as previously mentioned, worship on Saturdays.

As mentioned, Seventh Day Adventists are growing in number, with Adventists now found in multiple countries around the world. In total, there are approximately 21million Adventists, with this number expected to rise in forthcoming years.

9th – Presbyterianism – 40million

With 40million followers, Presbyterianism is a popular denomination. It is one of the older Protestant denominations, and has seen its numbers stay at a rather static level in recent years.

A denomination that has seen its numbers dramatically drop in recent years – Methodism has around 60million members worldwide. Based on the teachings and philosophy of John Wesley, Methodists are generally found in the United States and parts of Europe.

Compared to many denominations, it is one of the newer groups, and a renaissance in member numbers cannot be ruled out. The biggest Church in this denomination is the United Methodist Church – which has 15million members.

7th: Oriental Orthodoxy – 65million

A huge range of Churches make up Oriental Orthodoxy – with approximately 65million followers. Oriental Orthodoxy Churches are common in Northern Africa, the Middle East and some parts of Eastern Europe, especially Armenia.

Unfortunately, followers of this area of Christianity have been facing sickening persecution, with the world seemingly sitting back and doing nothing. It simply doesn’t fit today’s left-wing agenda to suggest that Christians are victims. Hopefully, the numbers will bounce back soon.

6th: Lutheranism – 75million

Lutheranism is one of the most popular denominations in Protestant Christianity, and has followers around the world. Lutheranism is particularly popular in many parts of the United States, as well as some European nations – especially those in Scandinavia.

5th – Baptists – 80million

A very well known denomination is the Baptists. There are around 80million Baptists around the world, with this denomination well-known for its belief that baptism should be only done by professing believers – rather than at childbirth.

Baptisms also involve full immersion – as John the Baptist did to Jesus Christ. The Baptists are one of the oldest Christian denominations. The largest Church within this denomination is the Southern Baptist Convention – where 14.5million members attend various Churches, it is based in the USA.

2nd – Pentecostalism 280million

A denomination that has seen membership numbers enormously rise in recent times is Pentecostalism. Such is its enormous growth, the denomination is now the second biggest denomination of all, and the largest in Protestantism.

This denomination is also one of the youngest in this list, with its phenomenal growth leaving many scholars perplexed. It is very popular in the United States, and is rapidly growing in the deeply-religious continent of South America.

Those who follow Pentecostalism are known for believing salvation can be attained by grace alone, and that experiences with God during religious worship is common, with speaking in tongue a common phenomena at services.

The Assemblies of God – with 67million members – is the biggest branch of Pentecostalism. Having roared up the table in recent times, Pentecostalism is likely to only get more popular as the years go by.

The Rosary is an iconic image of Catholicism

1st – Catholicism 1.3billion

Of course, the biggest denomination of all in Christianity is Catholicism. Enormously popular in the United States, Europe and South America, it is difficult to travel far around the world without seeing a Catholic Church.

Catholicism dates back thousands of years and currently has over 3,500 dioceses around the world. The Church is fronted by The Pope – who lives in Vatican City.

The core beliefs and principles of Catholicism derive from the Nicene Creed – featuring areas such as believing in one God, believing the virgin Mary is holy and other elements such as everlasting life and the resurrection of the dead.

Many Catholics are known for their deeply religious ways. The Church is also associated with abstinence, their stance on homosexuality and its method of communion.

The Catholic Church is simply enormous. With such a huge following – the Catholic Church is likely to thrive for many years to come.
