Christianity is the world’s largest religion

There are more than 2.4 billion Christians worldwide, which makes Christianity the largest religion in the world. However, in the near future, it is very likely that Islam will surpass and become the most followed religion since it’s the fastest-growing religion at the moment.

There are three main branches of Christianity

Christianity actually has lots of denominations but is often divided into three main branches, which are Catholicism, Orthodox, and Protestantism.

Sometimes the religion is divided even further into 5 main branches which are the Church of the East, Oriental Orthodoxy, Eastern Orthodoxy, Catholicism, and Protestantism. 

And within these branches, there are even more denominations. About 50% of all Christians are Catholics and hold the Pope as their highest spiritual leader. This is definitely one of the many interesting facts about Christianity! 

Christianity has 10 commandments

Just like other religions, there are usually some set rules that every devoted follower should obey. The 10 commandments were given to Moses by God and are basically the laws of God that each faithful Christian needs to follow. 

If you break any of these commandments you have sinned.

Sunday is the holy day

In Judaism, the holiest day is Saturday, and for Muslims, it’s Friday. But in Christianity, Sunday is regarded as the holy day of the week and this is also when people should rest. 

In Western countries, Sunday has historically been a day off work where almost all stores and businesses will be closed. The most important mass is also held on Sundays in the churches. Sundays are dedicated to the lord and worship. 

Easter is one of the main holidays

While Easter starts off with a gruesome reminder of the crucifixion of Jesus Christ on the Good Friday, it ends more happily with the celebration of his resurrection.

Easter is the biggest holiday within Christianity and in addition to family dinners, large masses are held in churches around the world.

There is no original Bible dating back to Jesus

Many people imagine the origin of the Bible as a single book, but it’s, in fact, an anthology of 66 books with various authors. The first printed bible dates back to 1455, and it’s known as the Gutenberg Bible, which is also the first book ever printed. 

It has been written and rewritten many times and even translated into more than 3000 languages during a period of approximately 1400 years. Furthermore, the oldest version existing of the Old testament dates back to the 2nd century BC.

As for the New Testament, there are also no original manuscripts of the scripture, but thanks to fragments and early copies, scholars are fairly certain that the Bible of today is more or less the same as it was originally written.

Approximately 100 million bibles are sold every year

Since the first printed Bible, the Holy book of Christianity has spread worldwide, and it consistently ranks as the most popular book in many countries around the world. An estimated 100 million Bibles are sold each year.

Christianity is one of three Abrahamic religions

Another interesting fact about Christianity is that it has the same god as Judaism and Islam. They all stem from the same origins of Abraham, and it’s known as one of the Abrahamic religions. 

Despite many differences between the three religions, there are also many similarities, and many of the characters mentioned in each holy book are the same person. For example, Jesus is mentioned many times in the Quran and is seen as one of the prophets. 

Jerusalem is the holiest city within Christian faith

Jerusalem is perhaps the holiest city in the world since it’s an important site for Jews, Christians as well as Muslims. In Christianity, there are many important places around Jerusalem, and the Church of the Holy Sepulcher is located here. 

Every year, many Christians travel to Jerusalem on a pilgrimage route to visit the ancient places of Jesus and other important Biblical characters.

Christianity teaches about heaven and hell

All branches of Christianity teach about heaven and hell. Heaven is the place where all faithful Christians will live for eternity in happiness and peace with God, and hell is where Satan (the Devil) resides. 

Hell is where you will end up if have sinned. What actually happens before going to hell differs somewhat between the Christian branches, but in each denomination, it’s an important part of the teachings. 

Most Christians are praying daily but it’s not mandatory

Prayer is an important part of Christianity, and most Christians will pray on a daily basis and say their grace to appreciate God’s blessings. Whenever you attend a mass in church, there will be praying during the service as well. 

But unlike Islam where a good Muslim should pray 5 times a day, there is no obligation to pray every day in order to be a good Christian.

You get baptized to get rid of your original sin

Every Christian should be baptized in order to cleanse your soul and become free of your original sin. Since the sin of Adam and Eve, the first people who ate from the tree of knowledge in the Garden of Eden, every human has inherited their sin. 

In Christianity, most babies get baptized after a short while, but it’s also possible to get baptized later on in life. The Priest will dip your head into holy water and follow the 4 steps of baptism, which are: Repent to God; Believe in the Lord Jesus Christ; Be baptized; Receive the Holy Spirit.

There are more than 316 000 missionaries worldwide

If you wonder how Christianity has spread to all continents around the world, the answer is a mix of missionaries and colonialism. Today, there are more than 316 000 missionaries traveling the world to spread the words of the Bible. 

One notable missionary who gained media attention worldwide recently tried to reach the Sentinelese to convert the native tribes to Christianity.

Some Christian denominations have more missionaries than others, and some also go from door to door to teach about their faith and God, such as the Jehovah’s Witnesses.

The Father, The Son, and the Holy Spirit

Also known as the Holy Trinity, which basically means that God is one God, but appears in three Divine persons. These are The Father, the Son (Jesus Christ), and the Holy Spirit.

This can be quite confusing for non-Christians as it could easily be interpreted that they are different beings, but they are all the same Divine being. 

God created the world in seven days

While Scientists claim that Big Bang is the event that created the world, Christians believe that it was created by God in a period of the following seven days. 

  • Day 1: Light
  • Day 2: Atmosphere / Firmament
  • Day 3: Dry ground & plants

More thoughts about Christianity

There is no doubt that Christianity has had a huge part in shaping the world into what we know it as today. For centuries, the Church has held huge power in many countries around the world, and still do today in some aspects. 

Many of the laws in Western society has origins in the Bible, and much of the moral beliefs of right or wrong also has origins from the teachings of Jesus. This also holds true for many Atheists growing up in Christian countries. 

There are many interesting facts about Christianity and its history that is worth learning more about, even if you’re not a Christian. In modern society, much of the Christian traditions and rules have slowly changed to fit a changing world. 

The church has also endured many controversies in recent years with priests taking advantage of faithful Christians as well as monks/nuns who have performed various sins. In many Western countries, Christianity is in decline as more and more people turn to Atheism. 

However, in Africa for example, there is an increase in Christian devotees, and by 2050 it’s expected that the continent will be home to most Christians in the world with more than 1.25 billion followers. 

Latin America also has a large share of Christian followers as well as the Philippines, so while Christianity decreases in Europe, it increases around the world, especially in poorer countries. This is definitely one of the many interesting facts about Christianity.

Respect, knowledge, and acceptance

I’m a firm believer in every human’s right to exist and the same value. No matter if you’re Christian, Non-religious, or follow any other religion in the world, we need respect and knowledge. 

I’m not a Christian, but I grew up in Sweden, which was very much a Protestant country during my childhood. So, in school, we learned moral beliefs out of this point of view.

Since then I have studied many religions around the world, including Hinduism, Taoism, Islam, Judaism, and Buddhism. I think that the essence of each religion is more or less the same. Every major religion in its true form speaks about respect, acceptance, honesty, and kindness.

No matter what you believe yourself, we should agree that faith is between each person and God, and we can all live in harmony if we promise to never hurt others intentionally.
