Christianity is the most popular religion in the world. Countries like the United States, Brazil, and Nigeria have millions of Christians. However, having many Christians isn’t enough to earn a spot among the most Christian countries. The population would have to be high compared to other religions. This list will show you some of the most Christian countries on Earth.
Vatican City
Vatican City might be independent from Italy, but it’s still entirely surrounded by it. Interestingly, while it has fewer Christians than most nations, it holds a unique distinction—its entire population is 100% Christian! What makes it even more fascinating is that everyone there follows the same denomination: Catholicism, with the Pope at its helm.
Romania
With a population of over 20 million, Romania boasts the largest Christian population on this list, with more than 88% identifying as Christian. The majority are Romanian Orthodox, followed by smaller groups of Protestants and Catholics. Although religious freedom is embraced, no other religion makes up even 1% of the population.
Papua New Guinea
Christianity in Papua New Guinea is unique due to the wide variety of sub-denominations that form a large part of the Christian population. Catholicism, Lutheranism, Seventh-day Adventism, Pentecostalism, and the United Church of Papua New Guinea each represent over 10% of the Christian community. In total, about 95% of the country’s population identifies as Christian.
Tonga
The church-loving kingdom of Tonga is made up of hundreds of islands, though fewer than 50 are inhabited. Christianity is deeply rooted here, with Methodism leading the way, representing about half of the population. Other significant denominations include Mormonism and Catholicism. After Christianity, the second-largest religion in Tonga is the Baháʼí Faith.
East Timor
Roughly one million and four hundred thousand people live in The Democratic Republic of Timor-Leste, an Asian country. Other religions share less than 1% of their population, while Christianity claims a whopping 99% of the population. Most of the country’s residents are Catholics, with a small fraction being Protestants.
Armenia
It’s been over a thousand years since Armenia became the first country to have Christianity as its official religion, and today, its high Christian population makes it relevant in Christian conversations. About 96% of Armenia’s population are Christians, and most are Orthodox, with the Armenian Apostolic Church having roughly 95% of the population.
Namibia
Namibia stands as one of Africa’s most Christian nations, with about 89% of its population identifying as Christian. The Lutheran faith holds the largest following, followed by Catholicism and Anglicanism. The remaining 10% of the population practice Buddhism, Islam, or African traditional religions.
Marshall Islands
Christianity has been the dominant religion in the Marshall Islands for over a century, with more than 96% of the population adhering to the faith today. Around 80% are Protestant, while about 10% are Catholic. Among the largest Protestant denominations are Assemblies of God and the United Church of Christ.
Moldova
Eastern Orthodoxy has been the leading denomination in Moldova for a long time. Over 90% of the population follow this denomination. Include other denominations, and you’ll find that about 93% of its population are Christians. Besides Christianity, no other religion takes a significant chunk of Moldova’s population.
Solomon Islands
Roman Catholic, Evangelical, and Anglican faiths are strongly represented in the Solomon Islands. Seventh-day Adventists and United Methodists also hold a good share of the population. All these sub-denominations come together as Christians to make up 93% of the country’s population. The remaining 7% is primarily made up of animists, with small groups of Baha’is and Muslims.
