Christianity is the most popular religion in the world with over 2 billion adherents. 
About 70% of the 328 million inhabitants of the United States are Christians.
Early Christianity had its roots in Hellenistic Judaism and the Jewish messianism of the first century and Jewish Christians were the first Christians. 
Christianity started with Jewish eschatological expectations, and it developed into the veneration of a deified Jesus after his earthly ministry, his crucifixion, and the post–crucifixion experiences of his followers

  • Christians believe that Jesus was the Messiah promised in the Old Testament.
  • Christians believe that Jesus Christ is the Son of God.
  • Christians believe that God sent his Son to earth to save humanity from the consequences of its sins.
  • One of the most important concepts in Christianity is that of Jesus giving his life on the Cross (the Crucifixion) and rising from the dead on the third day (the Resurrection).

    • God the Father
