Step-by-step explanation:
Christianity is a world religion that arose around 33 AD in Palestine, around the life and teachings of Jesus Christ described in the New Testament. Christians believe that Jesus of Nazareth is the Messiah, the Son of God and the Savior of mankind. Christians do not doubt its historicity.
Christianity is the largest Abrahamic and world religion, both in terms of the number of adherents, which are about 2.3 billion, and in terms of geographical distribution - in every country in the world there is at least one Christian community.
