Christendom is the collective population of Christians in the world. Christianity has linked many diverse peoples in one belief. These believers share something special regardless of their race or nationality. Catholicism, the very first form of Christianity, literally means “universal”. Christianity is the great equalizer, because whatever one’s nationality or social position, all are equal in the eyes of God. This is because all human beings have free will, and thus an equal opportunity to enter the kingdom of heaven. Christendom also linked scholars and artists throughout the world. Christendom has made it possible for very different civilizations to come together on the common ground of Christianity.
