Christianity refers to the belief in Jesus Christ as the son of God and the savior of the entire planet, as capture in the New Testament of the Bible. With about 2.2 billion believers, Christians represent about a third of the entire population of the world. Indeed, Christianity is the largest religion in the world in terms of adherents, and through the several different Christian churches, there can be a bit of diversity in the belief systems.
Contemporary Christian worship takes place in a number of denominations, especially in the main three of Catholicism, Eastern Orthodoxy and Protestantism. The history of Christian churches is ripe with war, divisions and general disagreements, which is part of the reason there have been so many splits from its original inception. However, all denominations are united under the belief in Jesus Christ, hence the name Christianity.
The term “Immaculate Conception” works its way into popular culture in various corners, especially when talking about the divinity of Jesus. But contrary to how it is widely presented, the Immaculate Conception actually refers to Mary, the mother of Jesus, and states how God granted her immunity from sin from the very moment of her conception. However, different Christian churches have different doctrines for different teachings.
Another one of the most widely held beliefs even among the secular is the perceived evil of the number 666. This comes from the Book of Revelation, a highly symbolic work of apocalypse likely written sometime between AD 70 and AD 95. But new translations of the early copies of Revelation state that the “number of the best” is actually 616, though, again, different Christian churches have different perceptions.
When it comes to source material for information on Christianity, the Bible is the authority. In fact, the Bible was originally written in Hebrew, Aramaic and Greek and has had to be translated into contemporary languages fairly recently. In the Bible, the word “God” appears in every single book except for the Book of Esther and the Song of Solomon.
