Christianity is the largest and fastest growing religion in the world. With over 2 billion members, it is natural that not all Christians follow the same traditions and doctrines, thus the existence of denominations. Christian denominations differ in beliefs such as salvation, the trinity, life after death and even the infallibility of the bible. While some these denominations are smaller and operate in smaller groups, some denominations such as Catholicism and Protestantism are bigger in size and operate in relatively larger groups. Here are the global estimated sizes of Christian denominations as of 2010.

As a devout Christian, I have always been passionate about the Christian faith. This inspired me to pursue a degree in Religious studies and a Masters in Theology in college. I have also been privileged to teach 4 Christian courses in a college and university. Since I am dedicated to spreading the word of God, I am actively involved in the Church.
