Can someone just write a few paragraphs in their own words of what Christianity is?

Christianity is a religion whose followers claim to follow Prophet Jesus and call him the son of God. A core belief of the Christians is the Trinity which states that God is three separate entities - a father, son, and a holy spirit. They also believe that Jesus was crucified as a sacrifice so that Christians can be saved regardless of their deeds. However, Christian beliefs are subjected to wide scrutiny. The Bible has been through a great deal of tampering and modifications, and there are many contradictions between different editions.
